Shotgun Guy

The Shotgun Guy, sometimes referred to by different names by different sources, is a recurring enemy in the Doom franchise.

Doom 3
See Z-Sec

Doom 64
The Shotgun Guy makes an appearance in Doom 64, but interestingly enough, it uses the sprite of the Zombieman, but with a different palette applied to change his suit to more like the original Zombieman, making both monsters extremely difficult to differentiate in the game's darkness. In this game, Zombiemen have green pants, while Shotgun Guys have grey ones. They first appear in MAP01: Staging Area. As with Zombiemen, they are left-handed.
