Under Siege is set for a North American PS3 debut May 3. Played within the confines of a medieval setting, the leader of the fortified collection of cities known as The Citadel unleashes a monstrous army on the world. A group of heroes from independent villages then band together to thwart his plans. The game is compatible with Move, but it is also playable with a standard PS3 controller. It also features two-player online or split-screen gameplay, and a mode and mission editor.
