not me either I still Don't understand what its actually about and its mostly confusing when I see a gameplay of it (or should I call a lets play of it) yet am surprise how it got poplar o.o
My brother plays it. I have seen a little bit of gameplay, but mostly he tells me all the stories of what he has done. He and his friend have done some crazy stuff. I would like to play it, but don't have the original game.
Well, its a Zombie survival Sim, as "realistic" as possible, and as player driven as possible.
You want to survive and be friendly? Band together and hope for the best, expect the inevitable. You will get shot, you will rage(usually), hackers (Major issue until Standalone - December 2012 ETA)and glitches will make you both despise yourself and yet make you beg for more...
Similar in aspects of Dark Souls playstyle for most people, Rage inducing yet so addictive.
I play it with a "shoot on sight" basis unless I know the player/s I'm around. This is also somewhat because I do enjoy driving around the map in a bus, running people down or having 6-8 of us bail out on top of 1-2 players and unload all the firepower
