The weapon of choice for the Galactic Ranger's riot squad, the Concussion Gun fired a shotgun-like blast of devastating titanium pellets that dealed more damage the closer the enemy is. Also good against swarms of enemies, or the occasional galactic riot. The gun did barely anything to tougher enemies, like technomite shock troopers and Ratchet clones.The Concussion Cannon was the upgraded version of the Concussion Gun.
There is a glitch that if you do not have the Concussion Gun when you are in the Medical Outpost Omega and you get it when you do not have all your weapons you will automatically have it.
This glitch doesn't work in the PS2 version.
