In Call of Duty 2, the PPS42 is infrequently found in the Soviet campaign. It is a submachine gun that accepts 35-round magazines. While it doesn't have the magazine capacity that the PPSh-41 has, it makes up for it with very controllable recoil. In fact, its recoil is almost exactly the same as the PPSh-41 in Call of Duty. This means that the PPS42 is very controllable and can be used at short or medium range with ease. Its lower rate of fire makes it easier to control as well, but this might be a disadvantage in close quarters.
The PPS-42 was originally slated to be in Call of Duty: World at War, but was dropped before the game was shipped. It's likely that it was replaced by the PPSh-41. Unlike the other cut weapons, it lacks a HUD icon, which suggests that it was dropped in an early stage of development. The only things remained are Create-a-Class image and animations. Posters of it can be seen in the multiplayer map Revolution. If Added, It has a 35 round magazine and has a controllable 700 RPM Rate of Fire. It will also have the same reload as in Call of duty 2. it also has a different muzzle flash from the PPSh-41.
It can be added to Zombies where it can be obtained from the Mystery Box. and When Pack a Punched in Der Riese, It becomes the Meat Grinder.
