Sanctum 2 is a sequel 2009's Sanctum, a hybrid FPS/Tower Defense game. To succeed you have to construct and upgrade defensive structures. What makes Sanctum unique from other tower defenses is that when the havoc starts, you jump right into the action with your own weapons and play a key role in the defense.
