and that gun that shoots mini-rockets at rapid fire rate from Duke Nukem 3D....
Ah, the good ol' Devastator. That gun was ridiculous. I loved it!
Of course, Mr. Nukem had access to several other great guns in that game:
The classic RPG - KABOOM!!!
The Shrinker (make your enemy small, then STEP ON THEM!)
The Freeze Ray (freeze them solid, then launch a kick to shatter them into tiny bits)
