2015 vs launch
The 2015 system has echo and sounds better than the current system and is much less buggy but is missing some of the things from launch.
The launch sound system has stronger echo and features npc footsteps but is very buggy and has many broken reload sounds and some other missing sound effects.
things broken on both:
green bridge rain sounds
various in mission sfx e.g. BTM breaching charges
flashbang beeps
thank you whurr for giving me some of these bnks <3333333333
