Wave Gun

The Wave Gun is a new Wonder Weapon that is set to appear in the upcoming zombie level Moon. It causes zombies to cough up blood,slowly expand while floating away, and then explode.

When Pack-a-Punched, the Dual Wielded version becomes "Porter's X2 Zap Gun".

Overview
While on Dual Wield the left gun fires similar to a Ray Gun, while the right gun fires like the Wunderwaffe DG-2. The Pack-a-Punched version, seen in this video, seems to cause the zombies perform some sort of extra animation before expanding. The gun can either be two guns or one, having the ability to be split apart.
