Dota 2 players will compete for a share of more than $10 million at The International in July, Valve has revealed.
Valve contributed an initial $1.6 million to the prize pool. It also adds 25 percent of the purchase price of Compendiums and related in-game goods to the pool, letting players contribute to the share.
The in-game items combine tournament bracket predictions with slots for users to select their favorite teams and players.
Players can level up their compendiums by watching matches or buying points with real cash, unlocking rewards like an exclusive in-game courier model, battle point booster, and a suite of "stretch-goal style" rewards.
The tournament will be held in Seattle's KeyArena from July 18 to 21 and will host 11 of the best competitive DotA teams, as well as four regional qualifiers.
Valve previously released a feature-length documentary on professional gaming on Steam. Titled 'Free to Play', the internally-produced documentary follows three professional Dota 2 players from different continents (Asia, North America, and Europe) as they compete to win $1 million in the first Dota 2 International Tournament.
Last year's prize pool totaled just under $2.9 million.
