Items" code, as well as the "Friendly Fire" option. Have one
player shoot the other player with the expander weapon. Enable the
"Invincibility" code before the first player explodes, then

Tiny

Hint:
Fire protection: Continually jump while over hot spots to avoid damage.
Hint:
Keep from blowing yourself up: When playing a two player cooperative game, turn friendly fire
off. When you go to blow up an enemy, will be prevented from killing
yourself.
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.
Hint:
Hear Butthead's voice: Begin game play on the Duke Burger level. Locate the drive thru
sign on the outside of the building. Approach the "Order Here"
sign and press A or move around to the center and back of the sign
and press A. Butthead's will say "Go 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 of the bend of the
attic. Step up onto the box, and then turn around to see the hidden exit.
Hint:
Grenade launcher level 1: Go to the projection room in the level 1. Jump on the projector
and get the Atomic Health. The wall next to you will open up and you can
collect a grenade launcher.
Hint:
Hollywood Holocaust: Hidden weapon 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.
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 with the Expander after
disabling the "Invincibility" 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.
