Duke Nukem 3d

The new weapons in registered Duke Nukem 3D and Plutonium PAK!

Shrink Ray - You've already seen this in a wall in the shareware version. You get to shrink your enemies to the size of a bug, and then crush them!
Microwave Gun - This is the new weapon in the Plutonium PAK. It's an upgrade to the shrinker where it adds a heat blaster. You need to get flame ammo for the upgrade. You will be able to switch between the Shrinker and the Microwave Gun upgrade by pressing [7] to alternate.
Devastator - This is a two-handed rocket launcher that shoots small sniper missiles.
Wall-Mounted Trip Bombs - These are like the traps in shareware levels 3 and 4. Attach one to the wall and it emits a laser beam. Cross the beam and BOOM!
Freezethrower - That's right, a freezethrower. Just shoot your enemies with this baby and watch 'em shatter!

One of the greatest things about Duke Nukem 3D are all the gags, hidden jokes the developers planted in the game and simply bugs. Here are a few:

If your down on ammo and you need a "Kick," try this: select Duke's kick as your weapon. Now press Ctrl and ~ together. Duke will kick with both feet. This is a great way to kill your enimies faster or get the most out of your steriods.
in Level one kill all the monsters and stuff but don't exit the level. Go to the door tht leads to the bridge that leads to the exit, now throw yourself in between the door! and press spacebar to close the door until you get crushed and die (make sure GOD mode is on) Then open the door and do the same thing again! now you are a floating disc! Press F7 to switch views to the view where you can see DUKE then fire a rocket and watch it fly out your a**! don't jump or fall a long distance or else to become normal duke again!
You need BUILD to see this. Go into E2L1, and (not moving from the initial location that your at) using the 2D mode, move yourself outside and into space. Go to the 3D mode, and you should be "floating" right outside the window, and right near that spaceship docked nearby. Float to the other side of that ship, and you'll see that it's name is, ironically enough: USS FRAMERATE.
go to E2L1. after you get the pipe bomb, stand next to one of the windows. face almost parallel to the window, but keep the reticle aimed out into space. toss a pipe bomb, and watch it sail away! a great way to get back at that pesky space ship. I don't know if you can blow it up, but it makes you feel good anyway.
There is a number on the bottom of a bench on E2L2 underneath the Earth Defense sign that reads 1138. The numbers "1138" found on E2L2 refer to the first movie that George Lucas made, entitled "THX-1138". And there are some places you can go to see messages from the levelord. One is on E1L5. There is a shrinker that hits you from another room across lava. Go to the lava room and use a cheat to get the jetpack and fly to the shrinker. on the wall is a message that says "You're not supposed to be here. Levelord" There is one other i found on E3L1. get to the end of the level and you see a crack in the wall you can look out of and see a building and stuff, us DNCLIP and go through the wall. Walk forward and look to your left and there is another message form the levelord. There are probably more. Also there is a rumor about a room with the designer's photo's. Look in the textures in the Levelmaker and you willl see them. But i don't know where they are in the game.
if you shrink SOME of the dancers (I am not asure which ones) and then give them money, they will stay shrunk it is really cool.
Play the launch facility with a friend and have one of you go inside the rocket and have the other hit the switch...well you don't go to the moon but you do explode!
You must freeze monster, then wait until he melt. Get the shrinker and shrink monster. Try not killing kim, just get freezer again, duck and schoot at him when he start growing. When he melt, he will be really small and shoot like always.
(5/27/96) - from -Falcon At any time that the height limit in any stage is high enough to fall from the top and die, turn on God Mode (DNKROZ/DNCORNHOLIO) and if neccesary, use the code to get the jetpack (DNITEMS/DNSTUFF). Fly all the way up as high as you can and switch to the view mode where you are standing 3 feet in back of Duke. Now, leaving God Mode on, fall all the way to what would be a gory death and notice that when he hits, it freezes on a few select frames of Duke's animations that show his head snapping back and him spitting blood. You can walk around like this, and even shoot with this glitch intact, but I think opening a door will cause him to go normal again.
(5/27/96) - from -Falcon There are two points in which you can try this Glitch: In the very beginning of the game, on the rooftop, or in the second level in the sewer. All you have to do is get to the vent that you drop down to get to the street or the shaft beneath the cover of the manhole and as you start to fall, repeatedly turn your jetpack off and then on, trying to let yourself fall a few inches each time. If you get it right, both the top and bottom openeings will mysteriously seal off and thery'll be no exit. The only way out is suicide. Time to whip out the old RPG and kiss your ass goodbye...
(5/22/96) - from Paul Forst / Iron DukeWhat you do, is got to any level with any women in it (strippers, cheerleaders, etc.) and shrink them (one side note: if you shrink the cheerleaders in the boss level - the Stadium - in episode 3, they unshrink bigger than before), once they have been shrunk select the freezethrower and fire at them. You will usually hear a cry like an alien dying and possibly a spurt of blood, but they will not die. Then when they unshrink, they will be indestructable. You can fire off 100 RPG's at them and they'll still keep on dancing. Also the aliens that always appear when you kill one of the girls will not appear if you use this technique... There is also another related glitch where you first freeze them, then shrink them and then freeze them again. When they unshrink they will be indestructable but you WILL be able to freeze them again, but this time they will still be dancing while frozen, and if you then walk up to them you'll shatter them to pieces. These glitches are in the full version, I don't know if they will or will not work with the shareware version ... Try it out and enjoy...
On the second board, collapse the building and blast open the pothole! Throw a gernade in the hole and watch the same gernade fall from the sky and go back into the pothole the same way you threw it in!
In the theater bathroom on level 1, check just above the urinals for a special phone number. Remember Tommy Tutone from the 80's?
Throw a pipe bomb or shoot an RPG into a teleporter. :-)
Hang out by the fire hydrant in level 1 with an RPG ready. Swallow the steroids and shoot a rocket back towards where you start the level. Then, immediately run after that rocket. Don't run into it or you're toast. Instead, run past it on the side. Then, turn around right as you reach the building. If you time it right, you can take the rocket right in the face. Then you get to see your blood spread all over the ground. Suicide has never been so fun! (by James C. Barnes)
Go into the bar next to the disco on level 2 and check out what's playing on the tube. Do the words "slow-speed chase" ring a bell? (Note : you won't get to see what's on TV if you fire an RPG into the room before entering.)
Turn off clipping mode with 'dnclip' and walk through a mirror. Neat effect!
Go into the chapel on level 3 and walk up to the altar. Shoot out both stained-glass windows and then press the space bar against the face panel. The cross will invert, and a passage will open on the left side. You'll find an octabrain and a corpse in a green space suit. Duke says, "That's one doomed space marine!" (If you haven't played Doom DeathMatch, you won't get the joke). There's a chaingun on the ledge behind the corpse, too.
Try this: go outside, turn on God mode, and fly up with the jetpack as high as you can go. Press F7 to turn on view mode, and then turn off your jetpack. After you hit the ground you'll get a nice view of what you'd look like if God mode wasn't on!
On Level 6, the Launch Facility, you start out facing a slow-moving turbine. Go between any two blades of the turbine, and drop a holoduke. Step back, and watch its behavior as the blades hit it. Utterly useless, but interesting.
Try using your pistol or shotgun to sink a few balls on the pool table near the bar on level 2. You can also hit the space bar against the table to shoot the balls, too.
On level 6, try tracking through some blood under the rocket and leaving footprints. Then, after you launch the rocket, the footprints are still there--hanging in midair.
If you kill an alien while he is standing under one the the vertically opening doors, the door will come down and squish the body, and whenever it opens after that it a stringy bit of flesh gets stretched between the two halves of the door.
Get a "shock" by touching the electrical outlet in the arcade in level 1.
Start a new game. Before descending down the vent, type in DNMONSTERS and then drop to the street. Grab the Rocket Launcher from the ledge (you all know where this is by now) and then go to the cinema ticket window. Stand back (I usually stand in the shadow of the air vent I came down) and shoot a rocket through the ticket window (use crosshair if needed). This will blow a hole in the side of the wall. Now go stand infront of the hole looking into the ticket booth and type DNMONSTERS This will turn the monsters BACK ON and the lizard who was originally in there will EXPLODE before your very eyes in a glorious display of body parts. Its a Kodak moment so keep your finger over the F12 key to share it with friends.
Edit the user.con file with a text editor, and you'll see how easy it is to change weapon strengths, max ammo supplies, and other stuff. A warning, though: weapon strengths are universal, so if you change the strength of the shotgun, the Pig Cop's will be just as powerful as yours.
(4/14/96 - from Warren Thiele) - Here is a little trick I know of. My friend found it in a DukeMatch, and it really caught me off guard. Go in the apartment behind the cinema sign and jump onto the left window ledge facing out. Duck down and move forward and back, but don't fall off the ledge. If you do it right you'll end up in the corner of the arcade beside the Duke Nukem game. Since you can hear your opponent hit the elevator in the arcade you can time it so that you can blast him with the RGB without him knowing what hit him. I am running Duke Nukem 1.1 shareware. I'm not sure if it'll work in other version.
