Weapon Info
http://www.bayserve.net/~mike/duke/weapons.html


The shareware version has six weapons, and the registered version has ten.

Kick
The good news is that you have an infinite amount of kicks. The bad news is that this weapon is only a mediocre defense against the weakest enemies. But used in combination with a dose of steroids, the kick has a bit more punch. Use it only as a last resort.

Pistol
 It's better than the Kick, but only because you don't have to move in close to use it. Depending on the difficulty level at which you're playing, you need three or four bullets to take out Assault Troopers and Assault Captains, and you need more than triple that for Pig Cops. To make matters worse, the gun stops firing to (automatically) change clips, exactly what you don't need when a Pig Cop has a shotgun in your face or when you're putting the finishing touches on a Dukematch opponent.
Gun contains: 48 rounds
Ammo packs: 12-round clips
Maximum ammo: 200 rounds


Shotgun
 Similar to the shotgun in Doom, it takes one good shot to kill Assault Troopers and Captains and just two or three good blasts to destroy Pig Cops and Octabrains. It can't be used to blow open walls, but you can't get hurt by firing it point-blank, so it's you're best weapon for firing at close range.
Gun contains: 10 rounds
Ammo packs: 10 rounds
Maximum ammo: 50 rounds


Chaingun Cannon
 The chaingun proves to be your most effective weapon when you have large numbers of aliens around you, due to the weapon's rapid fire and response time. On the other hand, it runs out of ammo very quickly for the same reason. But there's lots it lying around for you to find.
Gun contains: 50 rounds
Ammo packs: 50 rounds
Maximum ammo: 200 rounds


RPG
 You can cause some serious mayhem with this powerful weapon. Besides easily taking out every enemy (except Bosses) with one shot, the chances are good that any enemies within the grenade's blast radius will go up in flames, too. You can also use it to blow holes in walls to create shortcuts, but whether you're shooting an enemy or an object remember one thing: don't stand too close to your target! You're just as vulnerable to damage as the aliens.
Gun contains: 5 rounds
Ammo packs: 5 rounds
Maximum ammo: 50 rounds


Pipe Bombs
 Pipe bombs are more deadly than an RPG blast, and are perfect for when you have time to set a trap. They aren't too useful in a battle when having a quick reaction time is vital to your survival, or when your enemy is flying or swimming above you.
Here's how they work: after you toss a pipe bomb, the weapon in your hand changes to a detonator; you can either press Fire to detonate the bomb or throw another (and another, and another) and detonate them simultaneously. You can detonate them from anywhere on a level, including while you're looking at a security monitor. :-)
Gun contains: 5 rounds
Ammo packs: 5 rounds
Maximum ammo: 50 rounds


Shrink Ray (registered version only)
 A nasty device, the shrink ray will turn reduce your opponents to the size of a rodent. During this time, they can be easily stomped to death. Powerful, but a little risky to use around mirrors (which reflect the beam), and it can sometimes be hard catching the little buggers you've shrunk down.
Gun contains: 5 rounds
Ammo packs: 5 rounds
Maximum ammo: 50 rounds


Devastator (registered version only)
 This cruel weapon seems to be less effective in multiplayer than it is in single player mode, but it's still vicious, spraying dozens of miniature rockets in a diffuse pattern. The blast radius of any of these rockets is much smaller than that of the RPG, but you can saturate an area with them.
Gun contains: 10 rounds
Ammo packs: 10 rounds
Maximum ammo: 99 rounds


Wall-Mounted Laser Trip Bomb (registered version only)
 Quite handy for setting traps! Slap one up on a wall and it arms a second later, projecting a beam across the area. Breaking the beam instantly triggers the bomb. Laser trip bombs can also be detonated by other explosions nearby.
Maximum ammo: 10 rounds


Freezethrower (registered version only)
 Shoot your opponent with this weapon and turn them instantly into blocks of ice. While frozen, they can be shattered with a kick or shot from any weapon. In multiplayer mode, you'll notice that slain Dukes drop an Atomic Health (+50 Health) icon when they shatter, which can be quite nice. The freezethrower's ray bounces off any surface, however, which can be a handicap as well since you run the risk of freezing yourself.
Gun contains: 10 rounds
Ammo packs: 10 rounds
Maximum ammo: 99 rounds


Microwave Gun (Plutonium Pak only)
 New Weapon in this add-on pack by GT Interactive. You can add a new ammo type and hardware upgrade to the good old Shrink Ray and turn it into the "Microwave Gun". When activated, this wepaon will superheat a player or bad guy until they expand and pop like an over-cooked egg in a microwave. Don't be too close to them when they go, or you'll take some damage too. The addition of a little radar dish to the Shrink Ray looks cool. You can alternate between the Shrink Ray and Microwave Gun by pressing the "7" key.
