Amazon also gives a short description of the 5 maps that’ll be included with the Call of Duty: Black Ops 2 Revolution DLC.

• Downhill - A medium-sized map based in the French Alps complete with snow, chair lifts, and a strategically placed lodge.
• Grind - Set within the locale of the Venice, California
  boardwalk, this small skate park map is sure to deliver fast and
  frenetic Call of Duty action.
• Mirage - This Gobi Desert multiplayer map utilizes sand dunes
  to provide different levels of elevation and a sanctuary in
  the center as a natural chokepoint.
• Zombies – Die Rise - The Zombie apocalypse has invaded China, turning down town into a dilapidated and dangerous MC Escher painting.
• Peacekeeper SMG - This impressive sub-machine gun fills the open weapon slot in your load-out with power and accuracy.
