Call of the Dead is a Zombie map included in the Escalation map pack for Call of Duty: Black Ops. Treyarch called it "a unique Zombies experience" and is "a very special creation for all Zombie fans." The level is the first to feature actual celebrities fighting the zombies and features a celebrity as one of the zombies. The map takes place on a ship and the land next to it.
V-R11 & the V-R11 Lazarus The V-R11 Is a Wonder Weapon gained through the mystery box. Shooting a zombie with this weapon while it is un-upgraded turns the zombie into a human. While screaming this human will attract any zombies nearest to him and run into the frigid water around the map, freezing himself to death. On a side note, the VR-11 has a better use of temporarily calming George Romero and giving the wielder and his allies time to retreat towards water.
Wunderwaffe DG-2 Invented by Edward Rictofen during WWII to help win the war against the Allied forces. From several quotes from Rictofen himself we learn that the weapon is primed with 200,000 amperes of chained electrical current. The bolt shot from the weapon instantly kills the intended target and chains to ten other targets, potentially arcing back to the wielder of the weapon and electrocuting him or her, oddly enough the shock is not lethal enough to kill. Despite being a electrical weapon it has surprisingly high recoil, making it critical to aim one's shots carefully
