Wave Gun

The Wave Gun is one of the two Wonder Weapons that is set to appear in the upcoming zombie level, Moon.

Overview
According to Treyarch, the weapon will be able to cook zombies from the inside out, causing the zombie to slowly expand, then explode. The normal version makes the zombie start to cough up blood then slowly expand and float in to the air and explode, but the Dual Wielded just electrocutes them, in a similar fasion to the Wunderwaffe DG-2. Not much else is known at this time.
