Dota 2: Release
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, with the first few being sent out shortly after Gamescom. During the event, Newell speculated that Dota 2 would likely ship in 2012, despite original plans for a full release in late 2011.In September 2011, Valve scrapped its previous development and release plans, which would have kept the game in its closed beta phase for over a year. The new plans, which IceFrog revealed via an online announcement, were to begin beta testing as soon as possible and to implement the remaining heroes afterward. Simultaneously, Valve announced that the non-disclosure agreement for the beta was being lifted, allowing testers to discuss the game and their experiences publicly. After nearly two years of beta testing, Dota 2 was officially released on Steam for Microsoft Windows on July 9, 2013, and later for OS X and Linux on July 18, 2013.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 from the mod, as well as the first original hero, being added in 2016. Two months following the game’s release, Newell claimed that updates to Dota 2 generated up to three percent of global internet trafficIn December 2013, the final restrictions against unlimited global access to Dota 2 were lifted after the game’s infrastructure and servers were substantially bolstered.
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, the leading Beijing-based video game publisher, Perfect World, announced the acquisition of the exclusive rights of Dota 2 in China. The Chinese version 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. In November 2012, a similar publishing deal was made with the Tokyo-based company Nexon to distribute and market the game in South Korea and Japan. In November 2015, Nexon announced they would no longer be operating servers for Dota 2, allowing Valve to take over direct distribution and marketing of the game in those regions.
