well 4player coop with all those agile aliens jumping around, some pinger levelbosses, 4 people, 4 playstyles, rambo's, cloakers,
it should be awsome to see how the alien AI reacts on 4 different playstyles. besides that, coop is always fun:)
It's always 4, again, we should call it Left 4 Nanosuits for dead..
