Valve has released this year's Digital Compendium ahead of the Dota 2 International eSports tournament.
25 per cent of the Compendium's $9.99 cost is added to the tournament's overall prize pool. Furthermore, the more people who buy the Compendium the more content is unlocked for all owners.
The kitty currently stands at $1,917,155, meaning it has hit the first $1.6m stretch goal. There are plenty more stretch goals, however, going all the way up to a massive $15m.
Compendium owners will also unlock more content as they play the game by completing certain activities or purchasing Compendium Points.
Note that there is also a $26.99 ‘Level 50' version of the compendium, which from the off unlocks all rewards up to that level. Players will still be able to carry on levelling all the way up to level 250.
New for this year are Compendium Challenges, where you complete objectives in Dota matches. Complete a Challenge then win the match to earn Compendium Coins for both you and your teammates,” Valve said.
You can redeem coins in your Compendium for item or set drops. There are several ways besides Challenges to earn coins including random coin drops or by using Coin Charms. You can accelerate your coin earning rate with Coin Boosters that you can get by increasing your Compendium Level.”
