Valve sent over a press release announcing that Alliance are the winners of The International 2013 Dota 2 Championship, earning a prize of over $1.4 million. The five-day event culminated in a five-game match featuring Alliance vs. Na'Vi (Natus Vincere) competing in front of a capacity crowd at Benaroya Hall in Seattle, WA. For the first time, the prize pool was bolstered beyond Valve's contribution by Dota 2 player participation in the Interactive Compendium. With the community's involvement in the Compendium, the total prize pool was pushed from $1.6 million to over $2.8 million.
The International was launched two years ago in Cologne, Germany during Gamescom with 16 of the most elite Dota 2 teams competing in a group stage, double elimination playoff format for a grand prize of $1 million.
