the aliens invaded earth, and are trying to kill all the babes.
imagine if you would, some dude comes into your house, and wants to start killing everyone in order to make it his house.. and you worked hard for your house, you have dreams for you and your family..
what wouldn't make you want to rip off his head and shit down his neck?

I wonder what Duke did for a day job before he started saving the world?
He would have been a real prick in highschool

Duke is just p***ed at the alien b*****ds because, like he said in Episode 1 at the end ad Ep 2 in the beginning, "Nobody steals our chicks, and lives!"

Maybe he worked for the Umbrella Biohazard Containment Service ;)

I would say construction worker as well. I also thik that Douglas Quaid (from Total Recall) is "very Duke".

Whenever I think of the Duke, I can't help but think of his line. "It's time to kick ass and chew bubble gum... and I'm all out of gum."
Lo Wang from Shadow Warrior comes with: "Sticky bomb likes you!"
They both got their charm, can't decide on who comes first. Insanity wise, I reckon they're both the kind you'd not want roaming the street unless there be aliens on the loose. X-D
