The Psycannon is the instrument of vengeance with which you shall smite your foes. It is a singular weapon, rare and terrible to behold, made from psychoactive materials, the bolts fired by it channel your faith and righteous anger to hurt the daemon in ways nothing else can. Thus it is that Hate becomes our keenest weapon and Contempt, our surest armor.
As for the guns, I could mention the hugely satisfying penis extension gun that pins baddies to walls with entire trees, but all you really need to know is that is that there's a gun that shoots shurikens and lightning. I wish I could make something like that up, it shoots shurikens and lightning. The only way it could be more awesome is if it had tits and was on fire.

RY: Blackbeard has the weapon traditionally considered by children to be the ultimate destructive instrument, the bazooka.

AB: Only to be trumped by the bazooka that fires dinosaurs.

Adam: Ordinary household items can in fact be deadly, if Jamie builds a gun to shoot it.

"Doc" Schweitzer: Flintlocke, if we have a big giant cannon, why don't we just shoot... A cannonball?

Fargo Flintlocke: Bah, predictable! They'll see it comin'!

Schlock: The box said "Blattco Clawhammer", but I think it just shoots regular bullets.
Ebbirnoth: (without turning) If you ever do find a gun that fires hammers, you are under explicit orders to put it back where you found it.
