Gravity wrench

The Gravity Wrench is a deleted Covenant weapon intended for an early version of Halo: Combat Evolved. It was possibly the inspiration for the Plasma Pistol, and may have provided titular basis for the Gravity Hammer. In addition, it appears to be wielded like a flamethrower, or in Halo 3, other Support Weapons.

Trivia

 * The Gravity Wrench could have inspired the Gravity Hammer or being the concept weapons during the pre-production.
