Rick awakens in the dungeon of the mansion to discover that he is still alive thanks to the influence of the "Terror Mask," a Mayan sacrificial artifact from West's house which is capable of sentient thought. The mask attaches itself to Rick, fusing with his body and transforming him into a monster with superhuman strength. With the mask's encouragement, Rick goes on a rampage through the dungeon and the mansion grounds, killing hordes of monsters.
