Treyarch and Activision have officially released the trailer for ‘The Giant’ Zombies bonus map, which is included with a purchase of the Hardened, Digital Deluxe, or Juggernog Editions of the game.

Zombies returns in all of its undead glory with “The Giant,” a Nazi research facility featuring the weapon upgrading Pack-A-Punch Machine. Re-live the chaos of Treyarch’s classic “Der Riese” Zombies map, picking up the Zombies story with Dempsey, Nikolai, Richtofen, and Takeo where Origins left off.
