These weapons are mostly made from plastic and bullets.
M6G/B Pistol - A crap gun that is actually good, it is the same as the Halo 3 version, but it shoots twice as fast and it has the scope back! Just like the M6C/SOCOM, this is nearly as good as the M6D.
MA37 Assault Rifle - Time machines... It's basically the same as the Halo 3 Salt Rifle except that it looks different.
MA5D Assault Rifle - Well, finally the Assault Rifle is kickass!
Battle Rifle - A random rifle for battle.
Shotgun - A shotty that rhymes with shitty, which most likely means it's crap.
Flamethrower - Used to burn the Flood. Don't look at the AIDS when burning their popcorn, if you do you'll be stupified by their ugly, burnt look and will turn into a walking piece of crap like them. In short: Burn, biatch, burn!!
Rocket Launcher - The noob cannon, noobs use it by running up to the enemy and shooting the ground.
Spartan Laser - The Splaser is an awesome laser shooter, what else would you except?
Machine Gun Turret - A mini factory that makes bullets fast. Since, it never runs out of ammo and shoots fast, it's the fourth most abused weapon by Noobs. It's also recklessly broken into pieces by Master Chief and Noobs when they want a mobile turret. When it is broken, it only has 200 bullets to waste and since noobs are inaccurate at counting or winning, they think 200 bullets equal 6000 bullets and start to spam ammo crazy.
The weapons are made from pure hatred against vermin and mostly plasma.
Plasma Pistol - The pistol with green gooey stuff coming from the end.
Plasma Rifle - A rifle with blue plasma. Good to kill shields and people.

Needle Rifle - It's the Carbine mixed with the Needler
Concussion Rifle - The derp gun, I guess it's supposed to give you a concussion? I don't fucking know.
Spiker - A gun that was previously used as a stapler. It shoots spikes.
Mauler - A shotgun-pistol thing made by, the only ones stupid enough to make one, Brutes.
Carbine - The
aliens Covenant version of the Battle Rifle. Use with caution as the ammo case can give you a black eye.
Beam Rifle - The nub version of the sniper. It looks like a Vacuum cleaner
