"Damn! It's Late...": Microwaved rat
There is a room with a microwave. Directly under the microwave is a cupboard which can be opened to find a rat. You can pick up the rat and put it in the microwave. Note: This room is also shared with the Duke Nukem Fanboy.
Defeating the Alien Queen
When you first get in, and before you start the fight, fill your guns and explosives. Go to the right of the room where there are two trampolines. Crouch against the wall and the queen cannot hit you. Throw a pipe bomb at the first one. If it lands there, it will bounce to the second one, and to the Alien Queen. You should be able to tell when the bomb is near the queen -- detonate it when it is close. It will damage her. Continue this, but remember that she will send out bugs to kill you. The shotgun is the best weapon, as it kills them quickly. If you use the rocket launcher, be careful not to kill yourself. After the queen has lost two thirds of her health, the trampolines will close, and you will not be able to use them anymore. The queen will now send out Octobrains, which are much more dangerous than the bugs. For the Octobrains, use a machine gun. Make sure your rocket launcher is loaded, then return to the right side of the room. Find a spot on the wall where you can see the queen's head and launch rockets at it. Remember to sprint when going to the left of the room to get rockets, and to kill the Octobrains with your machine gun. Keep this up and you will defeat her, then make your way over there to finish her.
Duke will say "Tonight, you dine in Hell" after a kill in "Vegas In Ruins". This is a reference to 300, when Leonidas says "Tonight, we dine in Hell!"
Christian Bale reference
In the "Damn It’s Late" mission, after walking off the set you will see an actor yelling at someone. He says things like "Do you want me to trash you're mics? DO YOU?" and "You're a nice guy, you really are but you're a fucking amateur". This is a reference to when Christian Bale freaked out on the set of Terminator Salvation.
Dead Space reference
In "The Hive" chapter, after you tickle the first door, turn to your left and begin walking forward. You will have to crouch to get under the bridge. Once you do, you will see and dead EDF Soldier with Isaac Clarke's signature engineer helmet.
Donkey Kong reference
While ascending the stairs to escape the collapsing Hoover dam, barrels will fly down at you prompting Duke to say "Where's a hammer when you need one". When you reach the top and face the Pig Cop throwing them, he will add "Odd, I was expecting a monkey".
A female Fast Food employee makes the comment "I hope they make another season of Lightning Bug. That captain is hot".
At the start of the "Vegas In Ruins" level, before you enter the building there is a van with weapons. The armor in the van is the same from Halo, other than the Nukem insignia on the helmet visor.
In the Strip Club level, enter the room where you can microwave the popcorn. Look on the desk where you can use the security camera and you will see a spinning top, like the one Leonardo DiCaprio uses in Inception.
Leroy Jenkins reference
In the area outside the Lady Killer hotel and casino, Davis will assign Corporal Jenkins "The only one crazy enough to volunteer to go with Duke". Three minutes later, he charges the enemy and gets blown up. When Duke approaches the body he says "Damn it Leroy".
Mortal Kombat reference
In the Duke Nukem soundboard, there is an entry called "Fatality". when you select it, Duke says "Duke wins, Fatality."
Saints Row series reference
Sometimes when Duke kills an enemy in the "Duke Burger" Level, he will say "Better than Freckle Bitch's!". Freckle Bitch's is the fast food restaurant featgured in Saints Row and Saints Row 2, where the player can purchase food and drinks to restore health.
Starship Troopers reference
After killing some enemies, you will hear Duke say "I'm from Las Vegas, and I say kill 'em all!". This is a reference to Starship Troopers when Johnny Rico says "I'm from Buenos Aires, and I say kill 'em all!".
Tommy Tutone reference
In the bathroom in the Strip Club level, above one of the urinals there is some grafitti that reads "Jenny - 867-5309". This is a reference to the Tommy Tutone song of the same name.
