Pretty new to the game so I can't really offer pro-knowledge of it. (I'm only 8-10 hours in.) But I do feel like the game would be fantastic if played in a team. I've tried to group up with people in the game itself but you generally lose them the first moment infected attack and you both have to scatter and run. My timezone is GMT+1. I mostly play late afternoons/late evenings. Steam name is the same as my forum name here: Romburama
