Has anyone tried out Project Zomboid?
Just briefly, but even in the 20 or so minutes I had with it it's easy to tell that the game is really going places. Once they get online multiplayer in there (if it isn't already, I didn't notice) it should be a real contender.
Feels like something that will take many, many hours of your life from you. I just ran around a bit getting used to the controls and inventory etc. but had to bow out as I just didn't have the time free to really get invested. From what I've seen, though, I'd recommend it for zombie survival fans.
EDIT: Just saw that there's now a demo available. Give it a whirl.
