In level 1, go to the arcade and place a few pipe bombs on the elevator. When you hear the elevator go down, blow the crap out of him.
In level 1, place pipe bombs in either of the secret apartments and wait in the other. When you see your opponent enter the room blow the crap out of him.
Drop about 5 pipe bombs on a corner (works best on level 1 alleyway). Then turn on holoduke. When your opponent comes around the corner, be watching from the windows across the street. Boom!
Leave lots of pipebombs in any small room and tell your opponent they can find you there.(hehe. what a mess.)
In level 2, hop up on the ledge that is straight across from where the level starts (you can reach it by jumping on the vent shaft).
Crouch behind the palm tree. Use any weapon except the RPG and they wil never know you're there.
Study a level, so that you know all the back doors to places. (Just a tip)
In level 1, if your opponent knows about the secret apartment that is lit red, wait in there in the far corner opposite the couch when he comes in, blast him with the chain gun!
Hide near a placed holoduke and when your opponent shoots at him, blow him away from another direction. If you don't use the RPG he will continue to think it is the holoduke hitting him.
Place a few pipe bombs all around the back door to the cinema, then wait on the overhead bridge. When you hear the door open... BOOM!!
In the porno shop of level two, get the secret behind the cigarette counter. Place several pipebombs all around the room, especially by the door. Then go in the little secret. When you hear the door open, blast him. He will die no matter where he is, and you'll be shielded by the little cubby hole you are hiding in.
Another good idea is to go around and get to every one of the secrets before even looking for your opponet.
Place one or two pipebombs in every room of a level. Wherever he is, well you know.
In a game, place many holodukes. Get your opponet used to the idea of non-moving dukes. You will eventually be able to just stand there and not get hurt. Blast him!
To see if an enemy is a holuduke, use the night vision goggles and look at it. It will be different shades of green if it's real, and one shade if its a holoduke. If it's a holoduke, throw a pipebomb and blast the real one. ------ Sent in by Francois Levesque
Shoot at things violently to try to wound an oponent and run around like a chicken with its head cut off in a fight. ------ Sent in by Ali Babba
Get the holoduke in the level one arcade by using the Duke Nukem 2 game. Place it in the middle of the room and hide in a corner. When he comes in start shooting him. He'll never know you're there! ------ Sent in by Nate Ridlon
Place pipe bombs in the street and follow your opponent around with the jetpack. When he comes near a bomb, blast it. ------ Inspired by Matthew Sweeney
