Activision and Treyarch have added a couple of interesting additions in their new Zombies level included in their upcoming Call of Duty: Black Ops map pack, Escalation. An all-star cast of horror stars: George A. Romero, Robert Englunc, Sara Michelle Gellar, Michael Rooker, and Danny Trejo. In a press release announcing Call of the Dead, Treyarch said it "set out to create a zombie experience gamers have never played before". Personally I would just like them to fix the damn spawning issues in the game, host drop outs and the numerous glitches in the unfinished product. Hit the jump to check it out.
