Zapper

The Zapper (AKA Plasma Cannon) comes in three forms:

Grav Zapper
The Grav Zapper Shoots balls of plasma (deadly, but movable with The Hand.) These balls have gravity, and fall to the ground

ZeroG Zapper
The Zero G Zapper shoots balls with no gravity, but has all other qualities the same as the Grav Zapper

Pivot Zapper
The Pivot Zapper's balls have no gravity, and moves on a pivot when in play.
