Det blir proppat med kändisröster i Escalation, nästa expansion till Call of Duty: Black Ops. Treyarch meddelar att Robert Englund, Sarah Michelle Gellar, Michael Rooker och Danny Trejo ska kunna höras i nya zombiebanan Call of the Dead. En hyllning till George Romero, som även han dyker upp:
"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," säger Treyarchs Dave Anthony.
"It was an absolute honour 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."
Den 3 maj kommer expansionen till Xbox 360, en tid därefter till andra format.
