This prize pool has been raised thanks to the community who have contributed by purchasing Compendiums. $2.50 of every Compendium sale went into the prize pool, while those who purchased it were able to get their hands on rewards such as new game modes, extra emoticons, special HUDs and so on.
More details about The Compendium and the various unlocks are available from The International’s website. The community managed to unlock every original stretch goal plus the extra ones that were added after the prize pool surpassed $6 million.
The finals will take place in July and while all tickets are sold out, the event can be watched in full on Twitch.tv or in-game.
