It's not that great. It's in development hell, and the devs don't seem to be concerned with fixing the biggest issues with the game right now. At the moment, there is forget all to do in singleplayer. You get food (there's a lot of it), kill zombies (they infinitely respawn), and build a base. You have the potential to die on one hit, because zombie infection is a death no matter what. The devs seem to think that farming in real time and buildings falling apart due to age over the course of years is a priority when it loving isn't. The game needs stuff to do because once you've boarded up a few windows and have a year's worth of food in your closet it's just not worth playing anymore.
The combat is also sorta stuff. There's unexplained combat skills where the levels dont actually explain what they do, so you have no idea how to actually get better. Certain items are locked behind arbitrarily spawned crafting recipes. And almost anything you can build requires that you have at least 1 or 2 in crafting skill - which wouldn't be so bad if XP didn't increase terribly slow. AAAND if you want to level crafting you have to waste insane amount of wood, nails, and time on actually building loving fences or some stuff you DONT NEED to get something you do. It's a terrible system, and yet nobody who plays the game seems to have a problem with it.
I suspect this game is only really fun on a multiplayer server in which you have to worry about unfriendly players stealing your stuff and killing you, but every server on the list is PvE only, running a modpack that makes the game piss-easy.
Future updates are set to include a combat overhaul, animation overhaul, and vehicles, but so far only vehicles are in any playable state. Pick the game up after these have come out, they might make the game actually fun.
