Orcs Must Die! Unchained

Wisecracking multiplayer action that uniquely blends the strategic depth of a MOBA with intense third-person combat as you fight in a wild battle for fortress supremacy. Orcs Must Die! Unchained is a high-octane PvP action game in which you storm the opposing fortress together with your friends and defend your own base. Your enemies are also sending their minions to your rift – construct a maze of traps and beat back everything they send at you. Grinding, roasting, slashing or good old-fashioned thumping – every dirty trick is at your disposal when both attacking and defending.

Orcs Must Die! Unchained is a strategy/tactical game available on PC. It's free to play.
