I haven't really found any kind of thread where people can suggest and discuss guns / weapons that may or may not get added in future updates.
RS2, as it is right now, has a good foundation of firearms, but there are a few "essentials" still missing in my oppinion.
US:
- CAR 15, later XM177 variants
- Stoner 63
- M1918A2
South Vietnamese:
- M1 Garand
- M1 & M2 Carbine
- Browning Auto 5
Communist Party:
- Makarov PM
- Stechkin Pistol
- STG 44
- VZ 58
- VZ 24
- K50m
- PPS 43
- VZ 61
- PM 63
- MG 34 & 42
- ZB vz 26
So, I highlighted one specific gun for each side that should be considered a "soon be added to the game" gun.
I know, the devs are focusing on different topics right now, but guns in a game like Rising Storm 2 are an essential part for authenticity.
If you have any more suggestions (there were many more guns used in 'Nam then I have listed here), please write them down and I will update my list.
