Here's what I am looking for. I want a collection of Duke Nukem 3D weapons these will vary from. I don't want every single weapon, just the unique ones.
The ripper.

Which is a tri-barrel machine gun.
RPG

High powered missiles that are usually 1 hit kills direct or within 10-20 meters away.
Pipe bombs

You can throw these and detonate them. So you could detonate them in mid-air or leave them on the ground as mines.
Shrink ray

Shrinks anyone you point at and will die when stepped on.
The Devastator

Double barrel missile launcher that does about 30 damage per missile.
I don't care for ammo mods but I have an idea. So there will be an amount of ammo listed below on your screen, when it runs out it runs out. No reloading or reloading animations needed and
you can replenish ammo by picking up the same weapon found on the ground.
Steroids

What these will do is double speed, increased melee damage and restore shrunk players when shrunk by the shrink ray.
Medkit

Self explanatory
Holoduke

Shows a false image of yourself to distract players.
Jetpack

Sure you're going to say "OMG JUST USE PLAYER JETS!" Well this jetpack you could put on your back, when activated it is used like player jets but when you deactivate it you go back to your normal playertype.
KEYCARD!

Damn keycards.
