I'm bored. Lets come up with weapon ideas

I'm sitting here reading science journals, and I'm halfway dozing off. I need something to help keep me awake. How bout we propose new weapon ideas? Gives me a reason to keep my eyes open and continue work on the side. I'm sure everyone probably wants a handleful of the old weapons to return, but I think we should be giving ideas to new gun concepts; rather than living on nostalgia. You don't necessarily have to go into stats on the gun, but I think a name, weapon type, faction (ex. Milky Way/Andromeda/Remnant), rarity, and weapon function is a good way to structure an idea you might have. I'll give an example(s) of my own.

Coordinator (Remnant Automatic Pistol)
Ultra-Rare
The first shot in the clip is semi-automatic, and fires a beacon round that sticks to the enemy. All subsequent shots afterwards are automatic and home in on the location of the beacon. Given that it's a remnant weapon, the damage threshold would low, but its homing capabilities would make it deadly for shooting around corners and cover. Since it also tries to have the subsequent projectiles home in on the beacon location, it would also reward players who try to line up headshots; as every shot could potentially deal weakpoint damage.

Oracle (Asari Sniper Rifle)
Rare
An experimental two shot sniper rifle that uses concentrated mass effect field projectiles. It has a higher chance to stagger and improved stability over your average rare sniper rifle. Unique to this gun is its shot damage, in addition to its priming and detonating ability. The first shot is a high damage priming shot that sets up the target for biotic detonations and has a higher stagger chance. The second shot is a low damage shot that can detonate any primed targets (including enemies primed by this weapons first shot). The biotic explosion made from the first should would probably yield a smaller amount of damage, since it can readily detonate and prime enemies.

Didact (Heavy Kett Plasma Launcher)
Ultra Rare
A heavy Kett weapon, the Didact fires large plasma-infused bomblets that deal heavy splash damage to a wide area (relative to other explosive based weapons). It carries three shots per clip, and is very heavy (slightly more than the Soned).
