It's funny, I actually want to make weapons when I get older.
So basically when I saw this thread I got a huge boner.
And then, when I saw that 90% of the posts has to do with AIDS, my boner ran away.
List of weapons I came up with:
Charge Rifle
Basically, It shoots a round with plasma streaming off of it. Of course, all you would see would probably look like a lightning bolt. Won't tell you how it would work, because someday I hope to get a patent for it. I can tell you it involves Magnetic Charges and Noble Gases, though. Don't confuse it with a Rail Gun either.
Charge Grenade
Works on the same principles as the Charge Rifle, just amplified and uncontrollable.
HINT: IT'S A FRIKKIN PLASMA GRENADE.
Gamma Rifle
Just a thought, no idea how it would work.
Neuro-Disruptor Grenade
Creates a magnetic field/pulse so strong it disables brain function.
Flechette Grenade
I can probably make a working replica of a Halo 3 Spike grenade, just without the ricochet...
So yeah, Am I cool yet?
