Design a FPS weapon

[Spambot 3000]

The uh ... uh ... I'm not good with names
1) It's a flamethrower. That fires rainbows instead of fire. Or, rather, just rainbow coloured flames. Very pretty. Lots of added sparkles. Use to set people on fire.
2)Fire does continuous damage a short while after enemies are hit by the rainbow flame. Hit-and-run tactics or burn-'em-outta-dat-trench tactics. (Okay, yeah, maybe I am pilfering the idea for Pyro, so what, SCREW YOU.)
3)Not a long range weapon.
4)Obviously useless in a game where everyone dies in like, three bullets, (Call of Duty and stuff like that). Use in a pretty game, make extra pretty.

The Mouse, it's a mouse... that charges forward to be detonated, guided. Kinda like those soviet anti tank dogs.

 

[Ninjat_126]

A dart sniper rifle that boosts the health and damage of whatever player it hits, but messes up their HUD so they can't tell the difference between friendlies and enemies.

Come on, imagine how much fun that would be.

 

[Fasckira]

A grappling hook with a spike on the base part - fire at the enemy, the hook pulls him and right onto the spike. If the enemy is bigger than you, you get pulled into the enemy but the spike still goes in.

A localised suction explosion thing; fire at the enemy and all the air within a blast radius gets sucked out for a few moments, leaving the enemy gasping for breath. Will kill after repeated use but after a one use just leaves the enemy stunned for a moment or two.

Body ripper; similar to the grappling hook, a needle is fired which upon entering the targets body. After entering, it splinters up into chunks that immediately start borrowing into random directions within the body. After a second or two, all pieces will tear out of the body and return back to the firing gun.

Mole Mortar

The mortar shell has a drill bit on top and gets fired downwards. Targets anyone hiding behind chest-high walls.

I think this is from somewhere although.

 

[Sirron Kcuch]

A glove that is able to take whatever proyectile has been fired at you, and send it back with much more force.

Remember the Pyro's M2?, well, it's like that, but instead you just take that rocket and hurl it wherever you want it to go.

The karken
1) it shoots a spiked string, called tentacle, the arrow sticks to an enemy (unless they are armoured were it hits) and hten continuesly shock the enemy, You can have up to 8 tentacles active at a atime, but they become detached if the enemy gets too far away or is physically broken either by obstacle or attack.
2) it can do large amounts of damage to a single enemy if you land all 8 shots on it or it can damage up to 8 enemies and anything between those two options.
3) You can't reload it without breaking the strings and when all shoots are active you can't fight any other enemy.
4) a team based scifi FPS about hunting mythical beasts e.g. the actual kraken, a leviathan, dragons or even titans.

Shrieker rifle - it makes an organic enemies organs fail and they die after about 15 seconds, but they can still fight and kill you in that time and the gun only has 2 shots and takes a while to reload.

Mind control spider bot - remote controlled, can be destroyed in 1 hit, but can latch onto enemies. After 3 seconds, they "die" and you can control them to make them kill their teammates.

Mole Mortar

The mortar shell has a drill bit on top and gets fired downwards. Targets anyone hiding behind chest-high walls.

I think this is from somewhere although.

Digger Launcher from Gears 3!

So someone has made it! Neat.

The expander.

Think the bubble shield from Halo, except you use it as ammo that penetrates your enemies and then expands inside them. Messily.

1) extreme ultra-violence
2) extremely effective against unarmoured enemies, but worthless against armour/shields
3) see above
4) I could see it in something like Gears of War, but it's more or less similar to the Torque Bow, so.

This one actually exists in the game Duke Nukem 3D. It took a trillion hits on the riot tank, but regular enemies were toast after short exposure. When they died, they deal explosive splash damage to

 

[eternal-chaplain]

The Social Vampire
1. Effectively drains an enemies health and returns half of it to you by leeching via a pair of fangs shot from the weapon.
2. If health is low and no one is around to give you a boost, you might as well DIY.
3. To gain health, you must have TWO people leeched at once, otherwise no health is gained and the pair of fangs only deal slight damage, so while you can get all your health back from two people and kill them at the same time, you are open to twice the fire, plus it takes three seconds to fulfill the whole draining process (maybe holstering a certain sidearm reduces this time).
4. The game would, of course, have to use the master race of health systems (non-regenerating and denoted my numerals), and be largely team-based so that you could actually FIND a pair of enemies to latch onto.

Spoiler: I don't really have much to contribute, but there is this app for anyone who wants to make guns like this.

This is the most fun I've had in a long time...

 

[Wanderhome]

Best weapon ever was already made.
The Ghost Gun from Time Splitters 3, set that as the only weapon and play a round of 1-hit kills death-match with monkeys as toons, jumping, crouching, and dodging a pure beam of doom.

 

[DigitalAtlas]

Spoiler: Don't have to

Spoiler: They exist

Spoiler: But if I had to, I'd just port the weaponry from these games
