Origins characters Richtofen, Nikolai, Takeo and Dempsey embark on a suicide mission to an enemy research facility built upon an archaic site of unspeakable horror. Massive deposits of Element 115 have recently been discovered, delivering inspired new gameplay and - in Zombies tradition - a variety of plot twists and surprises to discover at every turn.—Activision
