I didnt see this in the DNSL, which is weird because someone should have suggested this already. Either way, here is my idea:
each side should have different weapon models and sounds, like 1smg.kv6 for green and 2smg.kv6 for blue. The changes are purely cosmetic (and audial because sounds should also be different), yet would help immersion greatly. Just imagine fighting with m4 when you hear a ak74 going off and you know that dirt is about to get heavy. This would mean a good distinction between the factions and should overall make the game better (awesome scenarios with thompsons and type100s for each faction). Your thoughts on this?
Edit: addzored a poll xD
