A few ideas for weapons. I hope you don't mind. You can change the values all you like.
MKIV Milkor MGL (just 'Milkor' for short)
Gauss, Semi Automatic
10 Round circular clip
Range Modifiers to accuracy: +3 close, +1 Medium, nil long
Damage varies depending on ammo
Grenade
Description: One of the oldest weapons around, made during the near start of World War III, the MIV MGL is still used today despite being extremely old. It is a coilgun, and has impressive range. It can fire EMP, HE, Napalm, Shockwave, Sound-bang (flashbang without the blinding), Flashbang, flare, bullet-style, shrapnel, or even whatever ferromagnetic things can fit into it's barrels, making the MIV MGL one of the most versatile weapons in existence while still being relatively cheap to make (though the ammo is not so cheap).
Reaper Automatic Shotgun
Single, 3 round burst, full auto
30 round clip
Range Modifiers to accuracy: +5 close, +0 Medium, -10 long
Poor to Great damage
Cone, Ballistic
Description: A very scary--but expensive--conventional automatic shotgun, the Reaper can put hundreds of small holes in unarmored targets. Without armor, you're dead. With good enough armor, you'll be left relatively unharmed. It's rare, but when it's there you had better get the hell out of the way or get ripped to pieces.
Sol Heavy Laser
Single
1 shot per 2 energy cells
Cohesion Modifiers: -3 close, +3 Medium, +2 long
Decent to Incredible damage
Energy
The Sol Heavy Laser is a extremely powerful laser made for anti-vehicle purposes. Eating two cells per shot and taking 3 seconds to fire while at the same time showing a small targeting laser up front and being quite heavy, the Sol is not really designed for anti-personnel combat. Regardless, it puts holes through anything in a matter of seconds, so do NOT get hit by it. It fires by shooting multiple--not a single--lasers, so it can also be raked for much less damage but at the same time being nearly impossible to dodge.
Opinions? Or are they awesomesauce weapons?
