Gauss Cannon

The Gauss Cannon is a powerful weapon that fires a burst of energy. Most enemies can be killed with one shot, though larger enemies, such as the Cacodemon and Baron of Hell, require more shots to kill. It shares its ammo pool with the Plasma Gun.

In the Beta, it was a "super weapon" that fired with enough power to cause a one shot kill, it holds 4 shots in multiplayer.
