Castle Dukenstein: Monsters in the Duke Burger Factory entrance
The Duke Burger Factory entrance is at the end of Gun Crazy. Step on the small box with the enormous shadow in the middle of the bend of the attic. Step up onto the box, and then turn around to see the hidden exit.

stash
Get a jet pack (located behind the movie screen) and go to the sign outside that is blinking. Fly up until you see the second black window up. Fly straight into it and inside you will find a large amount of guns, bombs, and sub-machine guns.

Defeating the final Boss
Make sure you have all of your guns. Since he cannot go off the stadium, walk on the edge of it so he walks in front of you. Make sure all you can see is his legs, then fire away. If done correctly, you should have a quick and trouble-free fight with out getting touched.

Huge dark Duke
To become a huge invisible Duke, have a friend shoot you with the Plasma Shotgun, and enable the "Invincibility" code. You will become dark Duke. Now, have your friend shoot you with the Expander after disabling the "Invincibility" code. After you explode, enable the "Invincibility" code again.

Glitch: Crazy elevators
This trick is best done with two people. In multi-player mode, select the Warp Factor level. Make sure there is no Dukebot to get in your way. Go to the area past the yellow key door (the giant moving ramp). Take a right turn and open up the wall to reveal a switch. Shoot the switch then run around to the other side of the large pillar in the middle of the room (or use a second player to enter, then re-open the door). A wall should be open. When you take the elevator up, you should be in a secret space ship location. However, instead of taking the elevator back down, walk into the same elevator. There are two elevators in the space station, but only the one you came in works with the trick. Close the door behind you. Get directly next to the door and start the elevator. You should be stuck in the middle of the closed door and the elevator. Move toward the elevator. You should have suddenly appeared in the elevator, and it should have stopped moving. Press [A] to get it to move again. This time it will not stop, and instead go faster. Have the second player call it back to get it to stop. If you do not stop, you will get stuck and must kill yourself or restart. After doing this, use the warp pad outside the big pillar to get near the space tram. The door should be open and the tram should be stuck in space. You can move out there freely, but if you go too far you will be killed. Hitting the switch near the open space tram door resets the tram and the elevator.
