Orcs Must Die! is a quirky blend of tower defense and third person shooter. You play as an apprentice warmage defending portals (rifts) from the orc world to our world. Each stage takes place in a different castle protecting a different rift. The warmage must place traps, cast spells, and use all the weapons at his disposal to prevent the horde from reaching the rifts, while trying not to be overwhelmed by his overconfidence.
