Call of Duty: Black Ops upcoming Escalation DLC will have a zombie level called Call of the Dead. Inspired by director George A. Romero (who will also star in the content) it will also feature the appearance and voices of Sarah Michelle Gellar (Buffy the Vampire Slayer), Robert Englund (Nightmare on Elm Street), Michael Rooker (The Walking Dead) and Danny Trejo (Machete).

“Our latest zombie creation, Call of the Dead, is unreal”, says Treyarch studio head Mark Lamia. “We set out to create an exciting new zombie experience for fans of the genre that takes Zombies to an insane new level.”

“This is Treyarch’s tribute to the legendary George Romero, who truly defined the zombie genre and whose incredible work has been such an inspiration to our team,” added Black Ops director Dave Anthony. “It was an absolute honor to work with such an amazing and talented cast whose passion and energy brought their characters instantly to life. Fans are going to love this.”

Escalation will release on May 3 for Xbox Live.
