Wave Gun

The Wave Gun is a new Wonder Weapon that is featured in the zombie level Moon. It causes zombies to cough up blood, slowly expand while floating away, and then explode. It can also be taken apart and Dual Wielded, where it becomes the Zap Gun Dual Wield.

When Pack-a-Punched, the Dual Wielded version becomes Porter's X2 Zap Gun, and the combined version become the Max Wave Gun.

Overview
The gun can be obtained in the Mystery Box. When first equipped, the gun is found in a Dual Wield mode. The left gun fires a projectile similar to that of the Ray Gun while the right shoots lighting bolts. However, the lightning does not continue on from the initial zombie hit. After hitting Left on the D-pad, the gun combines to become one weapon, firing a purple beam that causes the zombies to expand and explode. The Pack-a-Punched version, seen in this video, seems to cause the zombies perform some sort of extra animation before expanding. The gun has the option to split apart or be put together at any moment.
