Porter's X2 Ray Gun

Porter's X2 Ray Gun first appeared in Call of Duty: World at War and it continued to appear in Call of Duty: Black Ops and Call of Duty: Black Ops II. It appears in every map after Der Riese with the exception of Dead Ops Arcade.

Call of Duty: World at War
Porter's X2 Ray Gun is the Pack-a-Punched version of the Ray Gun. Improvements after Pack-a-Punching are damage from the splash of a Ray Gun shot improved from 1500-300 to 2000-300, the magazine size increases from 20 to 40 and the amount of ammo the weapon can hold changes from 160+20 to 200+40.

Call of Duty: Black Ops
The Ray Gun in Call of Duty: Black Ops is fairly similar to the Ray Gun in Call of Duty: World at War in terms of damage. The Ray Gun is better textured in Call of Duty: Black Ops than in Call of Duty: World at War and the Pack-a-Punch camouflage also differs.

Call of Duty: Zombies
In the iOS application, the Porter's X2 Ray Gun functions similarly to its consoles counterpart with the only difference being semi-automatic.

Call of Duty: Black Ops II
The Porter's X2 Ray Gun is similar to those in previous installments with the only difference being a different camouflage.
