CapCom Unity announces that Steam is now accepting preorders for Resident Evil Revelations, noting that this is another of those escalating incentive deals where more preorders will recursively trigger greater incentives to preorder. The game is due on May 21st, and the first reward of an art book and soundtrack is already unlocked. The next tier would add a free copy of Lost Planet: Extreme Conditions, and the third tier is for a season pass with four additional DLC packs, though what these will contain is not revealed at this time.
