Duke's in a Bar surrounded by Babes, DoomGuy busts in scoping the place. He was tracking some Ghoul but scared off the Chicks, Duke strutted over said "Get out 'o here Dick" DoomGuy stoic stepped past with a shoulder-butt, Duke cracked his knuckles "Hey enough is enough!"
DoomGuy hopped the Bar so now Nukem was pissed, He kicked out his mighty boot but it was met with a fist. The two just glared for what felt like a minute, 'till the slayer pulled a shotgun blam blam blam it exploded. Sheer destruction but the Duke didn't care, With his two golden eagles shooting shells out the air.
Duke threw a Pipebomb over the Bar, But the Beserker DoomGuy ran straight ahead with a saw. So the King flew high with a Jetpack whoosh, He smirked "What now budget Halo, You can't jump douche." But the Green death machine wasn't even phased, and open fired a Bazooka causing hellfire rain. But somethings wrong here cause Duke wasn't gibbed, Instead there was a Zap and then he started to glitch. It was a Hologram dammit where's this Arnie wannabe freak, Just then the Marine looks down and sees a Tripbomb on his cheek.
The armor is cracked yet DoomGuy just tanked it, They stagger buff to their feet down in the fiery rubble pit. Doom pulls a Chaingun and unleashes like a craze, But Duke has a Devastator rockets spread like a haze. One green flash and the missles are ka-put, Thats a BFG counter-strike and the f means get FUCKED!
But click out of ammo, That gun eats ammo. Duke says "Heh, Guess we'll settle this Mano-e-Mano" But then interrupts two shadows approaching, The Cycloid Emperor and CyberDemon standing there chuckling. They each have an army Aliens and Demons and they look pissed, Without a word Duke and DoomGuy do a bro-fist. With newfound respect they leap into the fray, When there's monsters to kill it's such a good day.
