I would actually prefer it if there was no gunfire in the ambiance. It would give the player less fear, just knowing that there's people nearby.
I agree. In real life if someone were to hear a gunshot they would freeze and look around for the source. Too many people in Bluzone just disregard that point and either ignore the shots or shoot back. And as for those who shot in the first place, it would make the whole atmosphere a lot better if you didn't fire a few rounds, unless you're fighting a zombie. Even still though, try hitting the zombies with melee, it's more efficient and doesn't hurt everyone Else's experience :)
