I don't know if this has been suggested and I don't have a ton of time to read through or search for this so if this is a repeat post, sorry guys. I know shooting on sight has been a big issue in the dayz mod. Most people will come close to each other and assume the other person is going to kill them. What if you had events that required teamwork or certain areas that are so loaded with zombies that it would be impossible to scavenge or get through without help from others. This would encourage grouping up and teamwork. Another thing is, most games have zombies that are attracted to sound. Also, gunshots are loud (especially from certain guns like rifles) and the sound can travel for quite a distance. What if you had it to where any gun shots fired attracted zombies within a certain radius.......say a half a mile or so. Or to break it up further, zombies in the immediate vicinity would go in a frenzied state to reach the sound but the farther away the zombies are, the slower they would start traveling toward the sound. So from the zombie's point of view, the louder the sound is, the more you're gonna want to try and reach it. That means if you had two people meet each other, they would have to seriously consider the consequences of shooting their gun which would possibly attract a horde of zombies numbering in the hundreds. I don't know, what do you guys think?.....
