The longer it's used on the enemies, the longer they're frozen. Fire Extinguisher: Freezes enemies that it hits.Flame Thrower: This is a hidden item on level 22 that does massive damage to bosses(and anything else for that matter).Whenever I fire this weapon I try to keep the character's back to the wall, preventing them from getting blasted back and allowing them to move right after firing. The only downsides of it is that its ammo can be hard to find and, when fired, blasts the character backwards a considerable distance. Rocket Launcher: This does massive damage to everything that the rocket hits, able to destroy walls, and open regular doors.These things shoot things to hurt things.
