 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 , <unk> , 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 those regions .
