There truly are few things more satisfying in a video game than watching a plan of your own invention be executed with immaculate success. For all its bells, whistles and promised hordes of greenskinned invaders, the real meat of Orcs Must Die happens in the moments before your fortresses doors are kicked down. You're given as much time as you need to survey the area, choose your traps and weapons, and begin crafting piecemeal your survival strategy for the waves ahead.

There are far more layers than the game's straightforward, titular directive would suggest. Over the next few minutes, you don't just have to make all of the Orcs dead. You have to tend to that very first seed of strategy, growing it into an engine of impenetrable destruction.
