Has any of me played this?
Yes, I'm playing it at the moment and it's quite good.
You don't have a clue what you're supposed to do at the start but after every body has been killed, you re-start the game with a better idea of what to do.
There are no levels - just one big map. You have to scavenge for resources, build up your base and locate other survivors.
I know we're all a bit "over" zombie games but this one has some nice twists to it.
