Robot Entertainment announced an extra incentive for owners of Orcs Must Die! to pick up the upcoming sequel. Ten stages from the original Orcs Must Die! will be available for free in Orcs Must Die! 2 for those who own the first game on Steam. The new maps will be playable in the co-op Classic Mode, which will feature the new traps and enemies from the sequel. If you don’t own the original game, you can pick it up for half price on Steam now.
