Dota 2 introduces 'Interactive Compendium' tournament companion
Valve has supplemented its upcoming "The International" Dota 2 tournament with a new virtual book, the "International 2013 Interactive Compendium." Available for $10 on the official Dota 2 shop, the Interactive Compendium will deliver news on the tournament and allow players to vote on tournament-related matters, such as post-tournament competitor awards.

The Interactive Compendium also unlocks "special virtual item drops throughout the tournament," according to Valve, in addition to matchmaking tournament-minded players and letting folks make predictions on tournament match outcomes. Once the August 7 event has come to a close, players will be able to read each other's Compendiums to see how accurate those predictions ended up being.
