Call of Duty: Black Ops' latest map pack, Escalation, comes out first for Xbox 360 owners on May 3, and Activision and Treyarch have dropped a video and a bunch of new screens for the DLC. No release date for the other systems nor pricing has been released yet.

The DLC includes five new maps:

  • Hotel takes place in a Cuban luxury resort
  • Convoy features an ambush on a U.S. military convoy
  • Zoo is in a zoo...a Soviet zoo
  • Stockpile continues the hunt for WMDs
  • Zombies
