The Ray Gun Mark II is a wonder weapon that was released alongside the Zombies map, Buried, and is featured in all Zombies maps in Call of Duty: Black Ops II. It is the successor and the evolution of the Ray Gun, although, unlike its predecessor, the Ray Gun Mark II fires in three-round bursts with no splash damage and has a 21 round magazine with 162 rounds in reserve. In Patch 1.12, the Ray Gun Mark II was unintentionally added to all maps (several days prior to Vengeance's release for Xbox 360), but was later removed swiftly via a hotfix.
