The third
DLC Map Pack for Call of Duty: Black Ops 2 is called Vengeance.
It includes four new multiplayer maps: Cove,
Detour, Rush and Uplink, a reimagining of the classic map Summit (from Black Ops 1) and the brand new Zombies adventure Buried with the
new bonus Zombies weapon, the Ray Gun Mark II. The DLC is available first on Xbox 360 on July 2, coming to PS3 and PC at a later date.
