Okay I had this really subtle but cool idea to add to the game, which could be really useful for people who pay close attention and observe their surroundings carefully. You are currently able to hear insects and birds in-game, right? What if when you or someone fired a weapon, the bird chirping would stop in the audible proximity of the gunshot for a while, like 10 minutes or something. It would be really cool, could make the game more realistic/immersive, and could alert players that gunfire has happened sometime recently in their area. Please let me know what you guys think!
