In the realm of fantasy is there a more mysterious creature than the orc? What are the orc’s hopes and fears? What does it dream about when it sleeps at night? Can an orc feel love? “Orc’s Must Die!” the new Xbox arcade game from Robot Entertainment doesn’t answer any of these questions, but for 1200 Microsoft points you can slice, burn, stab, smash, freeze, skewer, launch, and otherwise maim these disgusting creatures to your heart’s content.
