The game is a sequel to Defense of the Ancients (DotA), which was a community-created mod for Blizzard Entertainment's Warcraft III: Reign of Chaos and its expansion pack, The Frozen Throne. Dota 2 is played in matches between two teams of five players, with each team occupying and defending their own separate base on the map. Each of the ten players independently controls a powerful character, known as a 'hero', who all have unique abilities and differing styles of play. During a match, players collect experience points and items for their heroes to successfully defeat the opposing team's heroes in player versus player combat. A team wins by being the first to destroy the other team's 'Ancient', a large structure located within their base.
Jan 21, 2017 Dota 2 Overview. Dota 2 Free Download for PC is a free-to-play multiplayer online battle arena (MOBA) video game developed and published by Valve Corporation for Microsoft Windows, OS X.
Development of Dota 2 began in 2009 when IceFrog, lead designer of the original Defense of the Ancients mod, was hired by Valve to create a modernized remake for them in the Source game engine. It was officially released for Microsoft Windows, OS X, and Linux-based personal computers via the digital distribution platform Steam in July 2013, following a Windows-only open beta phase that began two years prior. As the game is fully free-to-play with no heroes or other gameplay elements needing to be bought or otherwise unlocked, revenue is made instead from microtransactions such as loot boxes, and a battle pass subscription system called Dota Plus, which all only offer non-gameplay altering virtual goods in return, such as hero cosmetics and audio replacement packs. The game has also been updated with various other features since release, such as a port to the Source 2 engine and virtual reality support.
Dota 2 has a large esports scene, with teams from across the world playing in various professional leagues and tournaments. Valve manages an event format known as the Dota Pro Circuit, which are a series of tournaments held every year that award qualification points for getting a direct invitation to The International, the premier tournament of the game with a prize pool usually totaling over US$20 million. Media coverage of most Dota 2 tournaments is done by a selection of on-site staff who provide commentary and analysis for the ongoing matches, similar to traditional sporting events. In addition to playing matches to a live audience in arenas and stadiums, broadcasts of them are also streamed live over the internet, and sometimes simulcast on television networks, with peak viewership numbers in the millions.

Despite some criticism going towards its steep learning curve and overall complexity, Dota 2 was praised for its rewarding gameplay, production quality, and faithfulness to its predecessor, with many considering it to be one of the greatest video games of all time. Since its release, it has been one of the most played games on Steam, with over a million concurrent players at its peak. The popularity of the game has led to official merchandise for it being produced, including apparel, accessories, and toys, as well as promotional tie-ins to other games and media. The game also allows for the community to create their own gamemodes, maps, and cosmetics, which are uploaded to the Steam Workshop. In the late 2010s, Valve released two spinoff games featuring the setting of Dota 2. The first, Artifact, is a digital collectible card game, while the second, Dota Underlords, is a chess-like game derived from Dota Auto Chess, a popular community-created mod from within the game. Dota 2 has also been used in machine learning experiments, with a team of bots known as the OpenAI Five showing the capability to defeat professional players.
Dota 2 is a multiplayer online battle arena (MOBA) video game in which two teams of five players compete to collectively destroy a large structure defended by the opposing team known as the 'Ancient', whilst defending their own.[1][2] As in Defense of the Ancients, the game is controlled using standard real-time strategy controls, and is presented on a single map in a three-dimensionalisometric perspective.[1][3] Ten players each control one of the game's 117 playable characters, known as 'heroes', with each having their own design, strengths, and weaknesses.[1][2][4] Heroes are divided into two primary roles, known as the core and support.[5][6] Cores, which are also called 'carries', begin each match as weak and vulnerable, but are able to become more powerful later in the game, thus becoming able to 'carry' their team to victory.[7][5] Supports generally lack abilities that deal heavy damage, instead having ones with more functionality and utility that provide assistance for their carries, such as providing healing and other buffs.[8][5][6] Players select their hero during a pre-game drafting phase, where they can also discuss potential strategies and hero matchups with their teammates.[2][5][6] Heroes are removed from the drafting pool and become unavailable for all other players once one is selected, and can not be changed once the drafting phase is over.
All heroes have a basic damage-dealing attack, in addition to powerful abilities. Each hero has at least four abilities, all of which are unique, which are the primary method of fighting.[3][8] Heroes begin each game with an experience level of one, only having access to one of their abilities, but are able to level up and become more powerful during the course of the game, up to a maximum level of 25.[2][5] Whenever a hero gains an experience level, the player is able to unlock another of their abilities or improve one already learned.[2][5] The most powerful ability for each hero is known as their 'ultimate', which requires them to have an experience level of six in order to use.[6] In order to prevent abilities from being used without consequence, a magic system in the game exists. Activating an ability costs a hero some of their 'mana points', which slowly regenerates over time.[3][9] Using an ability will also cause it to enter a cooldown phase, in which the ability can not be used again until a timer counts down to zero. All heroes have three attributes: strength, intelligence, and agility, which affect health points, mana points, and attack speed, respectively.[5] Each hero has one primary attribute out of the three, which adds to their non-ability basic damage output when increased.[10][5] Heroes also have an ability augmentation system known as 'Talent Trees', which allow players further choices on how to develop their hero.[5][6] If a hero runs out of health points and dies, they are removed from active play until a respawn timer counts down to zero, where they are then respawned in their base.[11]
The two teams—known as the Radiant and Dire—occupy fortified bases in opposite corners of the map, which is divided in half by a crossable river and connected by three paths, which are referred to as 'lanes'.[1][2] The lanes are guarded by defensive towers that attack any opposing unit who gets within its line of sight.[2] A small group of weak computer-controlled creatures called 'creeps' travel predefined paths along the lanes and attempt to attack any opposing heroes, creeps, and buildings in their way.[2][11][6] Creeps periodically spawn throughout the game in groups from two buildings, called the 'barracks', that exist in each lane and are located within the team's bases.[2][12][6] The map is also permanently covered for both teams in fog of war, which prevents a team from seeing the opposing team's heroes and creeps if they are not directly in sight of themselves or an allied unit. The map also features a day-night cycle, with some hero abilities and other game mechanics being altered depending on the time of the cycle.[5] Also present on the map are 'neutral creeps' that are hostile to both teams, and reside in marked locations on the map known as 'camps'. Camps are located in the area between the lanes known as the 'jungle', which both sides of the map have.[13][6] Neutral creeps do not attack unless provoked, and will respawn over time if killed. The most powerful neutral creep is named 'Roshan', who is a unique boss that may be defeated by either team to obtain special items, such as one that allows a one-time resurrection if the hero that holds it is killed.[2][14][6] Roshan will respawn around ten minutes after being killed, and becomes progressively harder to kill as the match progresses over time.[14] 'Runes', which are special items that spawn in set positions on the map every two minutes, offer heroes various temporary, but powerful power-ups when collected.[5][6]
In addition to having abilities becoming stronger during the game, players are able to buy items from set locations on the map called shops that provide their own special abilities.[2][14][15][6] Items are not limited to specific heroes, and can be bought by anyone. In order to obtain an item, players must be able to afford it with gold at shops located on the map, which is primarily obtained by killing enemy heroes, destroying enemy structures, and killing creeps, with the latter being an act called 'farming'.[2][11][5] Only the hero that lands the killing blow on a creep obtains gold from it, an act called 'last hitting', but all allies receive a share of gold when an enemy hero dies close to them.[3][11] Players are also able to 'deny' allied units and structures by last hitting them, which then prevents their opponents from getting full experience from them.[11][14] Gold can not be shared between teammates, with each player having their own independent stash. Players also receive a continuous, but small stream of gold over the course of a match.[16][5] Multiple game types in the game exist, which mainly alter the way hero selection is handled; examples include 'All Pick', which offer no restrictions on hero selection, 'All Random', which randomly assigns a hero for each player, 'Captain's Mode', where a single player on each team selects heroes for their entire team and is primarily used for professional play, and 'Turbo', an expedited version of All Pick featuring increased gold and experience gain, weaker towers, and faster respawn times.[17][18][19] Matches usually last around 30 minutes or more, although they can theoretically last forever as long as both Ancients remain standing.[6][20] In Captain's Mode games, an additional 'GG' forfeit feature is available to end games early.[21]
Dota 2 also occasionally features limited-time events that present players with alternative game modes that do not follow the game's standard rules.[22] Some of these included the Halloween-themed Diretide event,[23] the Christmas-themed Frostivus event,[24] and the New Bloom Festival, which celebrated the coming of spring.[25] Other special game modes have also been created by Valve, including a ten-versus-ten mode,[26] a Halloween-themed capture point mode 'Colosseum',[27] a combat arena mode 'Overthrow',[28] 'Siltbreaker', a story-driven cooperative campaign mode,[29] and 'The Underhollow', a battle royale mode.[30] The move to the Source 2 engine in 2015 also added the 'Arcade' feature, which allows for community-created game modes, with the more popular ones having dedicated server hosting by Valve.[31][32] One popular example, known as Dota Auto Chess, had over seven million in-game subscribers by April 2019.[33][34][35] Due to its popularity, Valve met with the mod's developers, the Chinese-based Drodo Studio, to discuss directly collaborating on a standalone version. However, the two companies were unable to come to an agreement, with them both stating that it was in their best interest to develop their own separate games.[36] While Valve's version, Dota Underlords, continued to use the Dota setting, Drodo's game, Auto Chess, was developed without using any Dota 2 assets.[37][38]
The Dota series began in 2003 with Defense of the Ancients (DotA)—a mod for Blizzard Entertainment's Warcraft III: Reign of Chaos—created by the pseudonymous designer 'Eul'.[39] An expansion pack for Warcraft III, titled The Frozen Throne, was released later that year; a series of Defense of the Ancientsclone mods for the new game competed for popularity. DotA: Allstars by Steve Feak was the most successful,[40] and Feak, with his friend Steve Mescon, created the official Defense of the Ancients community website and the holding company DotA-Allstars, LLC.[41] When Feak retired from DotA: Allstars in 2005, a friend, under the pseudonym 'IceFrog', became its lead designer.[42] By the late 2000s, Defense of the Ancients became one of the most popular mods in the world, as well as a prominent esports title.[43] IceFrog and Mescon later had a falling out in May 2009, which prompted the former to establish a new community website at playdota.com.[44] Valve's interest in the Defense of the Ancients property began when several veteran employees, including Team Fortress 2 designer Robin Walker and executive Erik Johnson, became fans of the mod and wanted to build a modern sequel.[45] The company corresponded with IceFrog by email about his long-term plans for the project,[46] and he was subsequently hired to direct a sequel.[47] IceFrog first announced his new position through his blog in October 2009,[48] with Dota 2 being officially announced a year later.[49]
Valve adopted the word 'Dota', derived from the original mod's acronym, as the name for its newly acquired franchise. Johnson argued that the word referred to a concept, and was not an acronym.[47] Shortly after the announcement of Dota 2, Valve filed a trademark claim to the Dota name.[50] At Gamescom 2011, company president Gabe Newell explained that the trademark was needed to develop a sequel with the already-identifiable brand.[51] Holding the Dota name to be a community asset, Feak and Mescon filed an opposing trademark for 'DOTA' on behalf of DotA-Allstars, LLC (then a subsidiary of Riot Games) in August 2010.[41]Rob Pardo, the executive vice president of Blizzard Entertainment at the time, similarly stated that the DotA name belonged to the mod's community. Blizzard acquired DotA-Allstars, LLC from Riot Games and filed an opposition against Valve in November 2011, citing Blizzard's ownership of both the Warcraft III World Editor and DotA-Allstars, LLC as proper claims to the franchise.[52] The dispute was settled in May 2012, with Valve retaining commercial franchising rights to the 'Dota' intellectual property, while allowing non-commercial use of the name by third-parties.[53] In 2017, Valve's ownership of it was again challenged, after a 2004 internet forum post from Eul was brought to light by a Chinese company known as uCool, who had released a mobile game in 2014 that used characters from the Dota universe.[54] uCool, who was previously involved in a lawsuit with Blizzard in 2015 for similar reasons,[55] along with another Chinese company, Lilith Games, argued that the forum post invalidated any ownership claims of the intellectual property, stating that the Dota property was an open-source, collective work that could not be copyrighted by anyone in particular.[54][56] Judge Charles R. Breyer denied uCool's motion for summary dismissal.[54][57] In March 2018, Blizzard filed motions to dismiss all claims against uCool and Lilith with prejudice.[58]
An early goal of the Dota 2 team was the adaptation of Defense of the Ancients's aesthetic style for the Source engine.[49] The Radiant and Dire factions replaced the Sentinel and Scourge from the mod, respectively. Character names, abilities, items and map design from the mod were largely retained, with some changes due to trademarks owned by Blizzard. In the first Q&A session regarding Dota 2, IceFrog explained that the game would build upon the mod without making significant changes to its core.[47] Valve contracted major contributors from the Defense of the Ancients community, including Eul and artist Kendrick Lim, to assist with the sequel.[59] Additional contributions from sources outside of Valve were also sought regularly for Dota 2, as to continue Defense of the Ancients's tradition of community-sourced development.[60] One of the composers of Warcraft III: Reign of Chaos, Jason Hayes, was hired to collaborate with Tim Larkin to write the original score for the game, which was conducted by Timothy Williams and performed and recorded by the Northwest Sinfonia at Bastyr University.[61][62] Valve had Half-Life series writer Marc Laidlaw, science fiction author Ted Kosmatka, and Steam support employee Kris Katz write new dialog and background lore for the heroes.[63][64] Notable voice actors for heroes include Nolan North, Dave Fennoy, Jon St. John, Ellen McLain, Fred Tatasciore, Merle Dandridge, Jen Taylor, and John Patrick Lowrie.[65]
The Source engine itself was updated with new features to accommodate Dota 2, such as high-end cloth modeling and improved global lighting.[49] The game features Steam integration, which provides its social component and cloud storage for personal settings. In November 2013, Valve introduced a coaching system that allows experienced players to tutor newer players with in-game tools.[66] As with previous Valve multiplayer games, players are able to spectate live matches of Dota 2 played by others,[66] and local area network (LAN) multiplayer support allows for local competitions.[67][68] Some of these events may be spectated via the purchase of tickets from the 'Dota Store', which give players in-game access to matches. Ticket fees are apportioned in part to tournament organizers.[69] The game also features an in-game fantasy sports system, which is modeled after traditional fantasy sports and feature professional Dota 2 players and teams.[70] Players are also able to spectate games in virtual reality (VR) with up to 15 others, which was added in an update in July 2016.[71] The update also added a hero showcase mode, which allows players to see all of the heroes and their cosmetics full-size in virtual reality.[72]
As part of a plan to develop Dota 2 into a social network, Newell announced in April 2012 that the game would be free-to-play, and that community contributions would be a cornerstone feature.[73] Instead, revenue is generated through the 'Dota Store', which offers for-purchase cosmetic virtual goods, such as custom armor and weapons for their heroes.[74] It was also announced that the full roster of heroes would be available at launch for free.[75] Until the game's official release in 2013, players were able to purchase an early access bundle, which included a digital copy of Dota 2 and several cosmetic items.[76] Included as optional downloadable content (DLC), the Dota 2 Workshop Tools are a set of Source 2 software development kit (SDK) tools that allow content creators to create new cosmetics for the heroes themselves, as well as custom game modes, maps, and bot scripts.[77][78][79] Highly rated cosmetics, through the Steam Workshop, are available in the in-game store if they are accepted by Valve. This model was fashioned after Valve's Team Fortress 2, which had earned Workshop designers of cosmetic items of that game over $3.5 million by June 2011.[75] Newell revealed that the average Steam Workshop contributor for Dota 2 and Team Fortess 2 made approximately $15,000 from their creations in 2013.[80] By 2015, sales of Dota 2 virtual goods had earned Valve over $238 million in revenue, according to the digital game market research group SuperData.[81] In 2016, Valve introduced the 'Custom Game Pass' option for creators of custom game modes, which allows them to be funded by way of microtransactions by adding exclusive features, content, and other changes to their game mode for players who buy it.[82]
Dota 2 includes a seasonal Elo rating-based matchmaking system, which is measured by a numerical value known as 'matchmaking rating' (MMR) that is tracked separately for core and support roles, and ranked into different tiers. MMR is updated based on if a player won or lost, which will then increase or decrease respectively.[83] The game's servers, known as the 'Game Coordinator',[84][85] attempts to balance both teams based on each player's MMR, with each team having roughly a 50% chance to win in any given game.[83] Ranked game modes with a separately tracked MMR are also available, which primarily differ from unranked games by making MMR publicly visible, as well as requiring the registration of a phone number to their accounts, which help foster a more competitive environment.[83][86] To ensure that each player's ranking is up to date and accurate, MMR is recalibrated around every six months.[87][88] Players with the highest possible medal rank are listed by Valve on an online leaderboard, separated into North American, European, Southeast Asian, and Chinese regions.[89] The game also includes a report system, which allows players to punish player behavior that intentionally provides a negative experience.[90] Players who get reported enough or leave a number of games before they have finished, a practice known in-game as 'abandoning', are then placed into 'low priority' matchmaking, which remains on a player's account until they win a specific number of games, and only groups them with other players who also have the same punishment.[91][92] Other features include an improved replay system from Defense of the Ancients, in which a completed game can be downloaded in-client and viewed by anyone at a later time, and the 'hero builds' feature, which provide integrated guides created by the community that highlight to the player on how to play their hero.[93]
In June 2015, Valve announced that the entirety of Dota 2 would be ported over to their Source 2 game engine in an update called Dota 2 Reborn.[94]Reborn was first released as an opt-in beta update that same month,[95] and officially replaced the original client in September 2015, making it the first game to use the engine.[96]Reborn included a new user interface framework design, ability for custom game modes created by the community, and the full replacement of the original Source engine with Source 2.[97] Largely attributed to technical difficulties players experienced with the update, the global player base experienced a sharp drop of approximately sixteen percent the month following the release of it.[98] However, after various updates and patches, over a million concurrent players were playing again by the beginning of 2016, with that number being the largest in nearly a year.[99] The move to Source 2 also allowed the use of the Vulkan graphics API, which was released as an optional feature in May 2016, making Dota 2 one of the first games to offer it.[100]
Dota 2 was first made available to the public at Gamescom in 2011, coinciding with the inaugural International championship, the game's premier esport tournament event. At the event, Valve began sending out closed beta invitations to DotA players and attendees for the Microsoft Windows version of the game.[101] Although the game was originally meant to publicly release in 2012, Valve later scrapped that plan as it would have kept the game in its closed beta state for over a year. Due to that, Valve lifted the non-disclosure agreement and transitioned the game into open beta in September 2011, allowing players to discuss the game and their experiences publicly.[102][103]
Following nearly two years of beta testing, Dota 2 was officially released on Steam for Windows on July 9, 2013, and for OS X and Linux on July 18, 2013.[104][105][106] The game did not launch with every hero from Defense of the Ancients. Instead, the missing ones were added in various post-release updates, with the final one, as well as the first Dota 2 original hero, being added in 2016.[107][108] Two months following the game's release, Newell claimed that updates to Dota 2 generated up to three percent of global internet traffic.[109] In December 2013, the final restrictions against unlimited global access to Dota 2 were lifted after the game's infrastructure and servers were substantially bolstered.[110] In order to abide by the standards set by the economic legislation of specific countries, Valve opted to contract with nationally based developers for publishing. In October 2012, Chinese game publisher Perfect World announced they had received distribution rights for the game in the country.[111] The Chinese client also has a region-specific 'Low Violence' mode, which censors and changes most depictions of blood, gore, and skulls in order for the game to follow censorship policies of the country.[112][113] In November 2012, a similar publishing deal was made with the South Korea-based game company Nexon to distribute and market the game in the country, as well as in Japan.[114] Three years later, Nexon announced they would no longer be operating servers for Dota 2, with Valve taking over direct distribution and marketing of the game in those regions.[115]
In December 2016, Dota 2 was updated to gameplay version 7.00, also known as 'The New Journey' update.[116][117][118] Prior to the update, the Dota series had been in version 6.xx for over a decade, marking the first major revision since IceFrog originally took over development of the original mod in the mid 2000s.[118] The New Journey update added and changed numerous features and mechanics of the game, including adding the first original hero not ported over from Defense of the Ancients, a reworked map, a redesigned HUD, a pre-game phase that allows for players to discuss their team strategy, and a 'Talent Tree' hero augmentation system.[117][118] In April 2017, Valve announced changes to the game's ranked matchmaking system, with the main one requiring the registration of a unique phone number to a player's account in order to play them, an anti-griefing and smurfing practice they had previously implemented in their first-person shooter game, Counter-Strike: Global Offensive.[86][119] Further changes to the game's matchmaking were brought in an update in November 2017, where the old numerical MMR system was replaced by a seasonal one based on eight ranked 'medals' that are recalibrated around every six months, a move that brought the game's ranked system closer to ones used in other competitive games such as Global Offensive, StarCraft, and League of Legends.[120][121][122]
In early 2018, IceFrog announced that he and Valve would begin on a different way to handle gameplay balance updates for the game. Instead of releasing larger updates irregularly throughout the year, smaller ones would be released on a set schedule of every two weeks.[123][124]Around the same time, the game also introduced the 'Dota Plus' monthly subscription system that replaced the seasonal battle passes that were released to coincide with a Major tournament. In addition to offering everything battle passes previously did, Dota Plus added new features such as a hero-specific achievement system that reward players who complete them with exclusive cosmetics, as well as providing hero and game analytics and statistics gathered from thousands of recent games.[125]
To ensure that enough Defense of the Ancients players would take up Dota 2 and to promote the game to a new audience, Valve invited sixteen accomplished Defense of the Ancientsesports teams to compete at a Dota 2-specific tournament at Gamescom in August 2011, which later became an annually held event known as The International.[126] From The International 2013 onward, its prize pool began to be crowdfunded through a type of in-game battle pass called the 'Compendium', which raises money from players buying them and connected lootboxes to get exclusive in-game cosmetics and other bonuses offered through them.[127][128] 25% of all the revenue made from Compendiums go directly to the prize pool, with sales from the 2013 battle pass raising over US$2.8 million, which made it the largest prize pool in esports history at the time.[129][130] Each iteration of The International since then has surpassed the previous one's prize pool, with the most recent one, The International 2019, having one at over $34 million.[131][132]
During its beta phase in the early 2010s, several other esport events would begin hosting Dota 2 events, including the Electronic Sports World Cup,[133]DreamHack,[134]World Cyber Games,[135] and ESL.[136] By the end of 2011, Dota 2 was already one of the highest-paying esport games, second only to StarCraft II.[137] At E3 2013, South Korean company Nexon announced the investment of ₩2 billion (approximately US$1.7 million) into local leagues in the country, which coincided with their distribution partnership with Valve for the game.[138] In February 2015, Valve sponsored Dota 2 Asia Championships was held in Shanghai with a prize pool of over $3 million, raised through compendium sales.[139][140] Since then, other Dota 2 Asia Championships have taken place, with it being sometimes being referred to as the 'Chinese International'.[141][142] In total, professional Dota 2 tournaments had earned teams and players over $100 million by June 2017, with over half of that being awarded at the International tournaments, making it the highest earning esport game by a margin of nearly $60 million.[143]
From late 2015 until early 2017, Valve sponsored a series of smaller-scale, seasonally held tournaments known as the Dota Major Championships, which all had fixed prize pools of US$3 million.[144][145] Their format was based on the tournament series of the same name that Valve also sponsored for their first-person shooter game, Counter-Strike: Global Offensive. Including The International 2016 and 2017, which were considered to be the cumulative Major of their respective seasons,[144][146] the series had five other events, which were the Frankfurt Major,[147]Shanghai Major,[148]Manila Major,[149]Boston Major,[150] and Kiev Major.[151] Following the International 2017, the Majors were replaced with the Dota Pro Circuit (DPC) format due to criticism by teams and fans for Valve's non-transparent and unpredictable nature for handing out International invitations.[152][153][154] In the DPC, teams are awarded qualification points for their performance in sponsored tournaments, with the top twelve earning direct invites to that season's International.[155] To avoid conflicting dates with other tournaments, Valve directly manages the scheduling of them.[154]
The primary medium for professional Dota 2 coverage is through the video game live streaming platform, Twitch.tv. For most major events, tournament coverage is done by a selection of dedicated esports organizations and personnel who provide on-site commentary, analysis, match predictions, and player interviews surrounding the event in progress, similar to traditional sporting events.[156][157] Live Dota 2 games and coverage have also been simulcast on television networks around the world, such as ESPN in the United States,[158][159]BBC Three in the United Kingdom,[160]Sport1 in Germany,[161]TV 2 Zulu in Denmark,[162]Xinwen Lianbo in China,[163]Astro in Malaysia,[164] and TV5 in the Philippines.[165]

Dota 2 received 'universal acclaim' according to review aggregatorMetacritic,[166] and has been listed by multiple publications as one of the greatest video games of all time.[176][177][178][179] In a preview of the game in 2012, Rich McCormick of PC Gamer thought that Dota 2 was 'an unbelievably deep and complex game that offers the purest sequel to the original Defense of the Ancients. Rewarding like few others, but tough'.[180] Adam Biessener, the editor who authored the announcement article for Dota 2 for Game Informer in 2010, praised Valve for maintaining the same mechanics and game balance that made Defense of the Ancients successful nearly a decade prior[16] and Quintin Smith of Eurogamer described Dota 2 as the 'supreme form of the MOBA which everyone else working in the genre is trying to capture like lightning in a bottle'.[169] The most frequently praised aspects of the game were its depth, delivery, and overall balance. Chris Thursten of PC Gamer described the gameplay as being 'deep and rewarding'.[173]
Martin Gaston of GameSpot complimented Valve for the artistic design and delivery of Dota 2, citing the execution of the user interface design, voice acting, and characterization as exceeding those of the game's competitors.[170] Phill Cameron of IGN and James Kozanitis of Hardcore Gamer both praised Dota 2 for its free-to-play business model that was not affected by cosmetic items, with Kozanitis stating that Dota 2 was 'the only game to do free-to-play right'.[171][181] Nick Kolan of IGN also agreed, comparing the game's business model to Valve's Team Fortress 2, which uses a nearly identical system.[182] Post-release additions to the game were also praised, such as the addition of virtual reality (VR) support in 2016. Ben Kuchera of Polygon thought that spectating games in VR was 'amazing', comparing it to being able to watch an American football game on television with the ability to jump onto the field at any time to see the quarterback's point of view.[183] Chris Thursten of PC Gamer agreed, calling the experience 'incredible' and unlike any other esports spectating system that existed prior to it.[184] Sam Machkovech of Ars Technica also praised the addition, believing that the functionality could 'attract serious attention from gamers and non-gamers alike'.[185]
While the majority of reviewers gave Dota 2 highly positive reviews, a common criticism was that the game maintains a steep learning curve that requires exceptional commitment to overcome. While providing a moderately positive review that praised Valve's product stability, Fredrik Åslund from the Swedish division of Gamereactor described his first match of Dota 2 as one of the most humiliating and inhospitable experiences of his gaming career, citing the learning curve and players' attitudes as unwelcoming.[186] Benjamin Danneberg of GameStar alluded to the learning curve as a 'learning cliff', calling the newcomer's experience to be painful, with the tutorial feature new to the Dota franchise only being partially successful.[187] In a review for the Metro newspaper, Dota 2 was criticized for not compensating for the flaws with the learning curve from Defense of the Ancients, as well as the sometimes hostile community, which is commonly criticized in multiplayer online battle arena games.[188] Peter Bright of Ars Technica also directed criticism at the ability for third-party websites to allow skin gambling and betting on match results, similar to controversies that also existed with Valve's Counter-Strike: Global Offensive.[189] Using Dota 2 as an example, Bright thought that Valve had built gambling elements directly into their games, and had issues with the unregulated practice, which he said was often used by underage players and regions where gambling is illegal.[189] Australian senator Nick Xenophon had similar sentiment, stating that he wanted to introduce legislation in his country to minimize underage access to gambling within video games, including Dota 2.[190] In response to the controversy, Valve and Dota 2 project manager, Erik Johnson, stated that they would be taking action against the third-party sites as the practice was not allowed by their user agreements or API.[191]
Comparisons of Dota 2 to other MOBA games are commonplace, with the game's mechanics and business model often being directly compared with League of Legends and Heroes of the Storm.[182][192][193][194] Contrasting it with League of Legends, T.J. Hafer of PC Gamer called Dota 2 the 'superior experience', stating that he thought the game was 'all about counterplay', with most of the heroes being designed to directly counter another.[195] Hafer also preferred the way the game handled its hero selection pool, with all of them being unlocked right from the start, unlike in League of Legends.[195] Comparing Dota 2 to Heroes of the Storm, Jason Parker of CNET said that while Heroes of the Storm was easier to get into, the complexities and depth of Dota 2 would be appreciated more by those who put in the time to master it.[196] Further comparing it to Heroes of Newerth, players from the professional Dota 2 team OG said that most Heroes of Newerth players were able to transition over easily to the game, due to the strong similarities that both games share.[197] Similar to other highly competitive online games, Dota 2 is often considered to have a hostile and 'toxic' community.[198][199][200] In 2019, a report by the Anti-Defamation League found that up to 79% of the game's playerbase had reported being harassed in some way while playing it, which topped their list.[201]
Following its reveal in 2011, Dota 2 won IGN's People's Choice Award.[202] In December 2012, PC Gamer listed Dota 2 as a nominee for their Game of the Year award, as well as the best esports game of the year.[203] In 2013, Dota 2 won the esport game of the year award from PC Gamer[204] and onGamers.[205]GameTrailers also awarded the game the award for Best PC Game of 2013,[206] with IGN also awarding it the Best PC Strategy & Tactics Game, Best PC Multiplayer Game, and People's Choice Award.[207][208] Similarly, Game Informer recognized Dota 2 for the categories of Best PC Exclusive, Best Competitive Multiplayer and Best Strategy of 2013.[209] The same year, Dota 2 was nominated for a number of Game of the Year awards by Destructoid, including the award for the best competitive game. While the staff selected StarCraft II: Heart of the Swarm, Dota 2 received the majority of the votes distributed between the nine nominees.[210]Dota 2 was later nominated for the best multiplayer game at the 10th British Academy Games Awards in 2014, but lost to Grand Theft Auto V,[211] and was nominated for Esports Game of the Year at The Game Awards at its 2015, 2016, and 2017 events,[212][213][214] while winning the award for best MOBA at the 2015 Global Game Awards.[215] The game was also nominated for the community created 'Love/Hate Relationship' award at the inaugural Steam Awards in 2016.[216] In the late 2010s, the game was nominated for Choice Video Game at the 2017 Teen Choice Awards,[217] for Esports Game of the Year at the Golden Joystick Awards and National Academy of Video Game Trade Reviewers Awards,[218][219][220][221][222] and as IGN's best spectator game.[223]
A month prior to its official launch, Dota 2 was already the most played game on Steam with a concurrent player count of nearly 330,000, which outweighed the number of players for the rest of platform's top ten most-played games combined.[224][225][226] It remained as the most played game by concurrent players on the platform for four years,[227][228] having a peak of over one million and never dropping below first place for any extended period of time until being surpassed by PlayerUnknown's Battlegrounds in 2017.[229][230][231] Viewership and followings of professional Dota 2 leagues and tournaments are also popular, with peak viewership numbers of some events reaching upwards in the millions.[232][233][234] Some Asian schools and universities, such as the Asia Pacific University of Technology & Innovation in Malaysia, have held courses on Dota 2, teaching students the fundamentals and core skills to use during the game.[235][236]Dota 2 has also been a part of traditional multi-sport events, such as under the esports category of the 2017 Asian Indoor and Martial Arts Games.[237]
The popularity of Dota 2 led Valve to produce apparel, accessories, figurines, and a number of other products featuring the heroes and other elements from the game. In addition, Valve secured licensing contracts with third-party producers; the first of these deals concerned a Dota 2 themed SteelSeriesmousepad, which was announced alongside the game at Gamescom 2011.[238] In September 2012, Weta Workshop, the prop studio that creates the 'Aegis of Champions' trophy for winners of The International,[239] announced a product line that would include statues, weapons, and armor based on Dota 2 characters and items.[240] In February 2013, the National Entertainment Collectibles Association announced a new toy line featuring hero-themed action figures at the American International Toy Fair.[241] At Gamescom 2015, an HTC Vivevirtual reality (VR) tech demo based around the shopkeeper of the game's item shop was showcased, allowing participants to interact with various items and objects from the game in VR.[242] The demo, known as Secret Shop, was later included the following year on The Lab, Valve's virtual reality compilation game.[243] After the conclusion of The International 2015, Valve awarded the Collector's Aegis of Champions, a brass replica of the Aegis of Champions award trophy, to those with compendiums of 1,000 levels or more.[244] Valve awarded the Collector's Aegis again the following year for The International 2016, as well as selling a limited edition Dota 2 themed HTC Vive virtual reality headset during the event.[245][246] In July 2017, an 18-track official soundtrack was released by Ipecac Recordings, including a version on vinyl.[247] A digital collectible card game designed by Magic: The Gathering creator Richard Garfield and Valve, titled Artifact, was released for PC-platforms in November 2018, and is planned for iOS and Android devices sometime in 2019.[248][249][250][251]
Promotional tie-ins to other video games and media have been added to Dota 2 since release, including custom Half-Life 2,[252]Bastion,[252]Portal,[253]The Stanley Parable,[254]Rick and Morty,[255]Fallout 4,[256]Deus Ex: Mankind Divided,[257] and Darkest Dungeon[258] announcer packs, which replace the game's default announcer with ones based on those franchises. In addition to announcer packs, well-known musical artists have written music packs that can replace the game's default soundtrack, such as electronic music artist deadmau5 and Singaporean songwriter JJ Lin.[259][260][261] To coincide with the Windows release of Square Enix's Final Fantasy Type-0 HD in August 2015, a bundle containing a custom loading screen, a Moogle ward, and a Chocobo courier were added the same month.[262] In April 2016, Valve announced a cross-promotional workshop contest for Sega's Total War: Warhammer, with the winning entries being included in the game later that year.[263] In 2017, a cosmetic set based on the Companion Cube from the Portal series was released as part of that year's International battle pass for the hero known as 'Io'.[264] In December of the same year, the character Amaterasu from Capcom's Ōkami was included as a courier for those who had pre-ordered the PC release of the game.[265]
A documentary on the game and its professional scene was produced by Valve and released in March 2014. Known as Free to Play, the film follows three players during their time at the first International in 2011.[266] American basketball player Jeremy Lin, who was a media sensation at the time, had a guest appearance in the film, where he called the game 'a way of life'.[267] Lin later compared the game and the professional gaming scene in general to basketball and other traditional sporting events, saying that there was not much of a difference between the two,[268] while also comparing various NBAall-stars, such as Stephen Curry, Kobe Bryant, and LeBron James, to different heroes in the game.[269]Starting in 2016, Valve began producing an episodic documentary series titled True Sight, a spiritual successor to Free to Play.[270] The first three episodes followed the professional teams Evil Geniuses and Fnatic during the Boston Major tournament in late 2016.[270] Three more episodes were released over the next two years, focusing on the grand finals of the Kiev Major, The International 2017, and The International 2018.[271][272][273] Valve have also endorsed cosplay competitions featuring the game's heroes, which take place during downtime at some Dota 2 tournaments and feature prize pools of their own.[274][275][276] Creation of Dota 2-themed animations and CGI videos, mostly created by the community with Source Filmmaker, also take place.[277] Similar to the cosplay competitions, Valve holds short film contests every year at The International, with winners of the competition also being awarded prize money.[278][279] In addition, Valve have created free webcomics featuring some of the heroes, further detailing their background lore.[280][281][282] A physical collection of the comics was released as Dota 2: The Comic Collection by Dark Horse Comics in August 2017.[283]
Dota 2 has also been used in machine learning experiments, with the American artificial intelligence research company OpenAI curating a system, known as the OpenAI Five, that allows bots to learn how to play the game at a high skill level entirely through trial-and-error algorithms. The bots learn over time by playing against itself hundreds a times a day for months in a system that OpenAI calls 'reinforcement learning', in which they are rewarded for actions such as killing an enemy and destroying towers.[284][285][286][287] Demonstrations of the bots playing against professional players have occurred at a number of events, such as Dendi, a professional Ukrainian player of the game, losing to one of them in a live 1v1 matchup at The International 2017.[288][289] A year later, the ability of the bots had increased to work together as a full team of five, known as the OpenAI Five, who then played and won against a team of semi-professional players in a demonstration game in August 2018.[290] Shortly after, OpenAI Five then played two live games against more skilled players at The International 2018.[291][292] Although the bots lost both games, OpenAI considered it a successful venture by stating that playing against some of the best players in Dota 2 allowed them to analyze and adjust their algorithms for future games.[293]

(help)Nowadays games like Dota and League Of Legends are described as MOBAs, which stands for multiplayer online battle arena – a laughably unhelpful term which is strangely fitting given how infamously difficult the games are to get into. And how notoriously unpleasant and elitist their online community tends to be.
