Hint: Entering the L.A.R.D. police station:
Locate the tunnel in the Freeway level. There is a
large box on one side of the tunnel. Jump on top of the box, and
from there jump on to the ledge. On the far side of the ledge
there is a pair of night vision goggles. Jump a little bit above
the goggles to enter the vents of the L.A.R.D. Police station.
Use the night vision goggles, and follow the air ducts and shoot
through the fan on the right side of the wall; or keep going and
break the second fan that also on the right side of the wall.
Duke may now explore the interior of the L.A.R.D. Police Station.

away. We're like closed".

Hint: Castle Dukenstein: Monsters in the
castle: Play a multi-player game and choose the Castle Dukenstein
level. This glitch is easier to perform when there is no Dukebot.
Select two players. Have one player walk into the bathroom on
the top floor and have the other walk into the room with the fireplace.
Have the player in the fireplace room get the night vision on
the couch and face the wall opposite the fireplace. Next, have
the player in the bathroom walk up to the place where there should
be a toilet. There is a chain-like thing hanging from the wall.
When you walk up to it Duke should say "Where is it?".
Pay attention to the player in the fireplace room. A wall should
open up. Turn on your night vision to reveal the monster in the
castle.

This trick requires two players. Play at the Castle Dukenstein
level. Have one player get night vision. That player should move
just outside the fireplace room in the hallway. Look at the wall
directly next to the red curtain in the hallway outside of the
fireplace room. Have the second player walk up the stairs in the
castle. When Duke reaches the top, you should hear a monster growl.
The wall should open, revealing another monster in the castle.

This trick requires two players. At the Castle Dukenstein level,
have one person move back and forth outside in front of the castle
doors. Have the other person move to the dining room area. Make
sure they have their night vision on and look under the picture
of the president. Make sure that the first player is still moving
back and forth outside. If done correctly, you should see the
third monster in the castle under the picture.

Hint: 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

around to see the hidden exit.

Hint: Freeway: The Terminator
reference: Find the building across the street with the conveyor
belts. If you go to the end, you will see a hydraulic press with
yellow and black caution tape with a Cyberdyne Systems Model 101
endoskeleton that has been severed at the torso and crushed. When
you walk over to it, Duke will say "Terminated". This
is a reference to the 1984 sci-fi action movie The Terminator.

Hint: Hollywood Holocaust: Hidden weapon
stash: Get a jet pack (located behind the movie screen) and

Hint: The Prison: Escape From L.A.
reference: In the second level (The Prison), you will find
a cell with a bed and a toilet. Press the door open button on
the toilet. A passage way will open up and you will find the severed
torso of Kurt Russell from Escape From L.A. You will then
hear Duke say "I guess he didn't escape after all."

Hint: 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.

Hint: 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

code. After you explode, enable the "Invincibility"
code again.

Hint: Easy Duke Match win: Enable the "Cheat mode" code and unlock the
"Invincibility" and "All Items" cheats. Do
not activate the "Invincibility" cheat yet. Start a
Duke Match. Activate the "All Items" cheat. Choose the
pipe bomb weapon and blow yourself up. As soon as you die, activate
the "Invincibility" code. You will return to life. Disable
the "Invincibility" code. You can now attack the Duke-bots,
but they will see you as dead.

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.

Glitch: Blackness in elevator: This trick requires patience and an elevator that can
be stopped in the middle of a call. Try it with the Spaceport
elevator with the broken lights. Enter the elevator. Go to the
bottom of the shaft and keep tapping A. The elevator should
appear to bounce. After a while, your journey up the shaft should
seem much faster than before. Keep pressing A and the elevator
will appear to be stuck at the bottom and have limited room to
travel. Press A a few more times and the elevator will
move again, only this time it will appear as if it were rocketing
out of then shaft. The walls will get blurry and after a while
you will be in blackness. Note: You can return back down. This
trick works with any elevator that can "bounce".

Glitch: Open door without keycard: In the Rabid Transit level in single player mode, near
the broken train is the blue keycard door. If you cannot find
the card to open this door, use Duke's foot to kick it.

Glitch: Floating Duke: Play a Duke Match game with all items on. Kill another
player or Duke Bot and enable "Invincibility" as soon
as they face plant the ground. The player or Duke Bot will now
be floating with their stomach facing the ground, resembling a
UFO.

In addition, the following secrets are present in the game.
Information in this section was contributed by John and Mason Corden.
In Duke Burger, the secret is in the meat locker room. After walking
in, face the two hanging pieces of meat. Shoot the one on the
left and open the wall behind it.
In Raw Meat, go to the end of the hall where the two babes and
Octobrains are located. Go behind the panel, then through the
window to just outside it. Turn right and follow the ledge to
the shotgun shells. Go just below them and walk into the wall
to a secret passage with a babe.
In Rabid Transit, take the transit to the end. Jump off and walk
to the "Keep Out" door. Open the compartment in the
pillar to your right.
In Area 51, hit the switch on the computer tower in the crate
room to open up a secret compartment in the crates.
