So yeah, this is something that I'm actually hoping to update every so often with new weapons, and here's the list of those I have right now:

Mag-7: Pump action pistol that uses shotgun rounds, 5 shot capacity.
Mag -7M1: Civilian version of the Mag-7, longer reload but better accuracy and less bullet spread.

M-93 "Black Arrow": Sniper rifle, 5 shot, slow reload and fire rate, but long range.
M-93 "Black Arrow" (C): Camo reskin of the M-93, credit goes to Nfsjunkie91.

Beretta CX4: Semi-auto rifle, 20 rounds.

HK SL-8: Another semi-auto rifle, 30 rounds, more powerful than the CX4.
HK SL8-1: Black reskin of the HK SL-8.

FN F2000: Assault rifle, 30 rounds.

Steyr TMP: Machine pistol, 15 rounds, dual and shield-wield capable.
Steyr TMP (OH): Offhand variant of the Steyr TMP.

SAR-21: 20 round assault rifle. Credit for sound goes to Prod.

L96: 5 shot sniper rifle, very accurate.

KH2002: 30 shot assault rifle.

Neostead: 12 shell capacity shotgun, longer reload than most.

Pirate Pistol: Pistol version of the Blunderbuss.

B-Shotgun: More powerful reskin of the shotgun, 8 shot, faster firing rate, slightly slower reload.

Hyper Digger: Your standard weapon-pack-grade more powerful digger.

Suicider: A powerful, portable device for those who would like to end their suffering on the battlefield in a way so that their enemies may feel it as well.

Concrete Bomb: A good hallway and doorway plugging device.

Gore Grenade: I got bored, it makes blood and limb pieces fly and stuff. Woo gore!

Have fun with it.

Oh sorry, fixing right away.

I can't test because i don't have the key...
