I'm all for the idea, since the heli crash sites are out in the open and you can simply pick off the zombies there from a distance without any risk. This system would draw a lot of player attention to it, making it an actual risk to go there(which is only normal, considering the rare loot in it). I'm not sure if it could be made so that zombies spawn there but there's no need for zombies at the crash sites in my opinion. The sound & smoke from the helicopter and the explosion would make more than up for the barely existant risk right now.

^ This + giving people slight advantages for spawning in certain spots, as to not having a mass Cherno/Elektro spawn.

This idea could be expanded entirely to the whole 'sound' system. Basically if a zombie hears you(while running for example) it goes to aggro state one, turns around and tries to look for you, in, for example, a 140 degree arc aimed in your direction. The arc could be widened/narrowed depending on the amount of sound you make and the distance between you and the zombie. Thay way sound would ONLY ever trigger aggro level one, while a zombie seeing you would trigger level two. Because honestly, when you hear gunshots from another player, you know their general direction but you can't exactly pinpoint their location. As for the zombies moaning and alerting other zombies, I don't exactly get what you mean, but I think a good(although probably difficult to implement) way to do this is to make a nearby zombie follow the zombie that moaned. So zombie 1 noticed a shot, moans, zombie 2 hears this, moans and follows zombie 1, zombie 3 & 4 hear this, moan and follow zombie 2.

Mfw Tyrone No hard feelings, had to do it.

Me and a friend were looting the ATC tower at the airfield near Balota, when I saw two survivors approaching from the town. I had a crossbow with two bolts left, and as my buddy was looking for loot, I was watching our surroundings from the top of the tower. Decided to shoot them since the crossbow made no sound, missed my first shot, luckily they didn't notice a thing. Second shot, I hit a guy in the chest, but he was still alive. Their mistake was going prone, making them an easy target for me. As one guy was bandaging himself my friend found a DMR in the ATC tower. I asked him to give it to me so I could shoot the two fellas. They were obviously still new to this game, as they only had makarovs & some tools. But I still decided to play things safe and finished them off. One in the head, the other one in the leg & shoulder. From then on, I've kept the DMR and shot every son of a bitch I've stumbled upon from a fair distance. Never even had any player who was aware of my position. I'm not a serial killer, I'm a killer for own safety. If people pose a threat and are heading to me or my goal, I won't be in doubt to shoot them.
