True, but with the helis and Arma, when they fall out of the sky they just blow up, unless the Main rotor keeps spinning to give it a safe landing..... (Not sure how it would work) But I am sure some thing could be done I guess... I guess what I mean by the Siren, people know what it is, yes but the intense part would be not knowing if they are going to come and get you, or some one else, or what town or forrest they will come from kinda thing... So the idea about chasing the longest living player may not be a viable option, but the uncertainty of where the zombies will come from was kind of more my point I guess...
