The rumors (and signs) are true. Call of Duty: Black Ops isn't done yet. Treyarch will release a third map pack, on the Xbox 360 first, on June 28. It's called Annihilation and will feature four maps: Hangar 18, Drive-In, Silo and Hazard.
"Players will also enjoy an all-new Zombies experience, Shangri-La," Black Ops' studio chief Mark Lamia said in a press release. He described the presumably four-player co-op level as "an exotic and mysterious map filled with deadly traps, dark secrets and innovative gameplay that will challenge even the most daring Zombie hunters."
No price was given, but it is likely to cost $15, as previous map packs have. And, if the pattern continues to hold, it'll hit the PC and PlayStation 3 about a month later.
