In the increasingly popular scheme, as increasing sales targets will be accomplished so will the rewards for pre-order.
Fans have already unlocked reward 1, which wins them “exclusive Team Fortress 2 items,” German and Soviet caps and badges. Steam offers an attractive offer for Company of Heroes pre-orders.
Reward two will win you a free giftable copy of Warhammer 40,000 Dawn of War II: Retribution. Finally reward 3 will get you in-game currency, which can be redeemed for future content, XP boost, unit boost and the commander archetype.
Of course as the next reward is unlocked you also get to keep all the previous ones. The game will be released sometime in March next year.
