This all-Zombies content pack hurls players into orbit with "Moon," the climax to the Zombies saga, as well as the most challenging and thrilling adventure yet. The undead shift in and out of sight, waiting for the perfect opportunity to strike. Undead astronauts easily shamble toward their next meal, unaffected by the base's fluctuating gravity.

Arm yourself with a space-age arsenal of epic proportions, including the Wave Gun, capable of cooking zombies from the inside out, as well as the Quantum Entanglement Device, which taps into the theories of quantum mechanics to bless (or curse!) your battle against the undead. Along with new equipment and an all-new Perk for thrice the zombie-slaying fun, you'll have the tools you need to turn back the undead tide once and for all. said by treyarc
