Duke Nukem is awesome. If you don't think so, then here's proof:
This is what happens when alien scum mess with the Duke (Screenshots from Duke Nukem 3D Polymer Hi-res pack):
Number 1: Trooper Heads
So, this is why Duke Nukem is awesome. Because he kicks butt without even breaking a sweat.
I used an Rocket Launcher to gib the Assault Troopers. Then, I picked up their heads, carried them to the lobby, and placed them in a line. I feel sorry for those troopers, though. I know that it probably doesn't feel very good to have a rocket slamming into you and then gibbing you.
