I've never been a fan of avp2 multi-player, it was way to slow, clumsy, and bright compared to the original game where speed and dark environments alone made for a quick and reactive if you will, scary and skilled experience.
When i heard Avp2 died i wasnt surprised as i only played a few games online. But one thing i remember was I never tried out this Evac mode your talking about, kinda wondered what that was all about, sounds like an interesting way to play under the theme of aliens.
Do you start at one location and try to make it to an evac zone? what happens when you die? start over in beginning location and your friends have to help everyone evac dangerously leaving the evac zone in order to help the rest? if so i feel like i might have missed out abit lol
