George Romero, Sarah Michelle Gellar, Danny Trejo, Robert Englund… it sounds like the cast of one seriously awesome horror flick… Even better, it’s the new Call of Duty Game: “Call Of the Dead.”

It isn’t really a full game, it’s more of an expansion pack and if you have an X-Box 360 than you’ll be one of the first people to get a crack at it. Also, if you have an Xbox 360, there’s a good chance that you didn’t just get your identity stolen like 77 million Playstation users.

Here’s the official statement:

On May 3rd, download “Escalation”, the second Call of Duty: Black Ops map pack, to play as the zombie-killing dream-team of Sarah Michelle Gellar, Robert Englund, Michael Rooker, and Danny Trejo against a new and unnerving zombie menace. 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.
