Is this the greatest zombified video game trailer after Dead Island? I think so. To promote the latest DLC for Call of Duty: Black Ops, Activision put together this insanely awesome trailer that stars Sarah Michelle Gellar (Buffy), Robert Englund (A Nightmare on Elm Street), Danny Trejo (Machete) Michael Rooker (The Walking Dead), and the father of zombie films George A. Romero (Night of the Living Dead). The DLC content pack is called “Escalation” and it’s described like this: “Set in a mysterious, ice-covered, remote Siberian island and inspired by legendary writer and director George A. Romero, a group of four fearless explorers fight for their lives amidst an army of bloodthirsty Soviet zombies.” Watch the Robert Rodriguez-inspired (Planet Terror) trailer above and anticipate Escalation’s May 3 release.
