Crap graphics, but is still alpha.
Gameplay is good, you do feel like oh crap night is coming where to hide. No rambo stuff here!
Saying that it hasn't grabbed me enough to play for long, but I did have fun with Aciid & Medi on multiplayer. Worth a look if cheap offers on.
DayZ also interests me, but sounds more like a bandit game.
Mind you H1Z1 looks better than either of the above.
