Hey guys, I would like to invite you to the discussion here : http://steamcommunity.com/app/108600/discussions/0/523890681402856420/ Point is the choppers are unrealistic (the traffic is way too high, event too long and frequent) and in general, the noise is SPAWNING zeds, be it this chopper/gunshot noise, it does not matter. Which is breaking immersion, imho. Thanks for the ideas and consideration. TL;DR: noise spawning zeds, which it shouldn't
