What is a b.f.g in dead rising 2

The BFG is the weapon created by a amplifier and a blast frequency gun. The BFG earns a lot of PP and kills many zombies as it fires a energy ball that wipes out the zombies. I think you have 15 shots when created and i think 300 PP per zombie when you have the combo card. It kills gas and normal zombies instantly, i dont know if it affects humans.
