"The PUMPER is like a shotgun. Having flashes at the end of the trail, it lets you hurt people near the trail. This weapon has a limited firing range." — World of Padman Manual

The Pumper is a shotgun-like weapon in World of Padman. It emits a powerful explosion at the end of the trail that damages enemies within its radius. It should be used in mid-range combat because the player may hurt him/herself when engaging in close quarter combats. Self damage can take up to 25 points of health. There's a significant delay between shots, almost as long as Splasher's, so try not to miss.

•The Pumper is most effective at medium range, as it can deal heavy damage to enemies within its radius. It is possible to frag two enemies in a single shot, provided if both enemies are in low health.

•When paired with PadPower, the player can perform Pumper jumps without dealing self damage. This is especially useful when trying to get to hard-to-reach areas.

•The Pumper is based off of the Shotgun from Quake 3 Arena.
