To promote the upcoming release of their all-Zombies content pack for Call of Duty: Black Ops, Treyarch has posted a new live-action zombie labs video and we've embedded it for you to watch. The Call of Duty: Black Ops Rezurrection downloadable content pack will be available exclusively for the Xbox 360 on August 23rd for 1200 Microsoft Points.

"The Call of Duty Zombie Labs has identified you as a genuine authority on the art and science of killing zombies, and we feel our recent research will prove invaluable to you and your audience. We have recently identified a rogue zombie population on the Moon - a horrific population of the angriest undead we've seen yet. We have therefore begun battle preparation for Lunar Deployment.

The following video presentation will bring you up to speed on some unconventional tests conducted here recently. The Call of Duty Zombie Labs strives to understand every facet of zombie physiology and psychology in order to help experts like you keep the Zombie onslaught at bay. We believe there are few who are as qualified as you to disseminate this critical information, and help us recruit every die-hard zombie killer out there capable of rising to our biggest challenge yet."

“Lift off into the ultimate Zombies epic and be the first to launch into space for a new dimension of undead action!

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.

In addition to the final chapter, Rezurrection also includes:

- Four re-mastered levels from Call of Duty: World at War: “Nacht der Untöten,” “Verrückt,” “Shi No Numa,” and “Der Riese,” where it all began.

- An enhanced Zombies soundtrack INCLUDING, three tracks never before available for purchase.

- A new Zombies “Moon” theme.

Those of you that purchased the Black Ops Hardened or Prestige Editions and already own the four re-mastered maps, the other contents in the Rezurrection content pack will be free, including Moon, the soundtrack and the theme.

For players that haven’t purchased the Hardened or Prestige Editions, Rezurrection will be available for 1200 Microsoft Points. To commemorate release, we’ll be hosting Double XP over Labor Day weekend. The Call of Duty: Black Ops Rezurrection downloadable content pack will launch worldwide, first on Xbox LIVE on August 23rd, 2011.”
