The Afterburner

The Afterburner is the Pack-a-Punched version of the MP40, which appears in Call of Duty: World at War, Call of Duty: Black Ops, and Call of Duty: Black Ops II in the maps Der Riese, Kino der Toten, Call of the Dead, and Origins.

Call of Duty: World at War
In Call of Duty: World at War, the Afterburner is only usable by Pack-a-Punching it on Der Riese. The result of damage is doubled, as the MP40's damage is 100-60 and the Afterburner's damage is 200-120. The result of the fire rate increased from 535 to 600. The magazine size is doubled, from 32 bullets to 64 bullets. The appearance gains a shinier body with several areas with decorated engravings on them.

Call of Duty: Black Ops
Pack-a-Punching the MP40 is only available on the maps Kino der Toten and Call of the Dead. The result after Pack-a-Punching is the same as it is in Call of Duty: World at War (details seen above). Otherwise, the appearance gains a golden-like body with red, tech engravings.

Call of Duty: Black Ops II
On the map Origins, the MP40 can be Pack-a-Punched and be given a blue camo, unlike the previous versions of The Afterburner.
