Sales of Valve’s Dota 2 Compendium have already pushed the total prize pool for the third annual world championships event past $2 million.
At time of writing, The International’s prize pool is sitting at $2,022,717 – $2.50 is added every time someone purchases a copy of the Compendium.
It’s not yet clear how this prize will be split among competitors, but in previous years the top ranked team took home $1 million.
Although that money will mostly benefit the teams chosen to compete in the event, Valve has provided a number of stretch goals available to all participants.
The Compendium costs $10 and is a sort of all-purpose guide to and community hub for The International, which takes place in August.
