In the newest expansion pack for Call of Duty: Black Ops, the user may play as a slew of characters such as Freddy Kreuger, Danny Trejo (from "Machete"), and Michael Rooker (from "Henry: Portrait of a Serial Killer" and "The Walking Dead"). The expansion, Escalation, taps into our favorite pastime by allowing players to kill zombies! The map called "Call of the Dead," which was inspired by George A. Romero (pretty much the inventor of the modern zombie), is the only map on which the enemies appear as zombies. But wait, there's more... Players on this map can use the aforementioned characters of various horror movies in addition to a character called Buffy Summers (Sarah Michelle Gellar). You may or may not remember her from the last few weeks of class. She is sort of a big deal, and a highly-anticipated addition to the game-playing experience. Furthermore, it appears that you wont be limited to a wooden stick as means of killing as Buffy is seen wielding a pistol in the promo video. Also, the vampires are much more realistic and actually provide a formidable enemy to exterminate over and over again.
