The Cryon Venom Needler.
A weapon which looks like the Alien gun from Half Life 1.
From your hand to your elbow, your arm will be covered by the weapon so it will act like a new arm. It has 10 needler 'loops'. The loops aren't really loops, more holes in the arm. See crappy paint drawing below.
Projectile 'Needle':
Needles do about 4 damage when hit in the chest. This may seem little, but they will inject Venom into the target (2 damage each sec, for the remaining life time.) They are slow projectiles compared to everything else, but you can't outrun them.
Needles can be shot down, but are really too small to hit bullets. Fire and explosives work best.
Needles follows the target you aimed at when you fired them. Once the target is behind them then they will just fly straight.
Needles have a limited life time, as they can't fly forever. Something like 12 seconds.
Primairy Fire:
Rapidly fires 5 Needlers each second.
Secundairy Fire:
Fires 10 needlers at the same time in big spreaded direction. Makes it harder to destroy them all in one shot.
Special Fire:
Locks an enemy, the needlers you fire will follow the target much better than normally untill they die and fall to the ground. To lock someone you need to hold Special fire and look at the target for a whole second. While locking you can shoot stuff.
Switching Fire Modes:
Increase the projectile speed for less damage.
Or decreases the projectile speed for more damage.
There are 20 needles in each ammo pack, an ammo pack is a organic sack to be placed into the weapon somewhere...
You can hold 3 needler ammo packs. So that's 60 max +20 in the gun.
Armor:
The weapon protects your arm, at the cost that it can be destroyed.

The grey stuff is where the needlers go trough. Figure out the rest by urself ^^
