Cannongun is a weapon available in Painkiller: Overdose. By the usage, this weapon resembles Rocket Launcher/Chaingun from original version. However, instead of shooting one rocket it shoots three smaller explosives. The chaingun which is mounted in the cannon deals greater damage. It can be found in Desert.
