I had some random weapon ideas that could be added into the game at some point in time.
VSS Vintorez: This is a sniper rifle with a built in silencer
Honey Badger: a compact SMG, also with a built in silencer
Stoner 63: straight mag or drum mag fed light MG
The Thompson: Just because its a futuristic game doesn't mean we still cant have the classics.
FN FAL: Single action assault rifles are still popular (right?)
M60: A classic MG, i'm surprised its not in the game already.
Uzi OR Mini Uzi: Either or will work tbh
Remington 870 shotgun: Compact version would work well
Barrett 50 cal: again, a good classic from FPS games, surprised that this isn't in the game already as well
If you have some weapon ideas to share post them in the comments
