A bleak take on the Zombie Survival genre.
Just as a bit of a disclaimer this game isn't finished, it's currently in a pre-alpha state, but it definitely shows off what the developers are trying to do already. It's less in the vein of Left 4 Dead and more The Walking Dead in terms of tone, so you're not trying to kill the zombie hoard as much as you are just trying to survive. And man if it isn't fairly brutal. There's definitely some inventory management issues that I ran into while, simply because I'm a ridiculous pack rat, just trying to pick up absolutely everything that I can. While that is generally a good thing to do you do need to setup various stores throughout the world, because there's no way you can keep all of it and you'll generally need somewhere safe to be in at night.
I'm not quite sure of what the scale of the world is, you start in the suburbs but it does seem like a relatively large town so far. That said you do run into other survivors, and there isn't that much interaction to be done with most of them for the moment I'm sure that's something that they're working on. For the most part you can see that they're mostly just individuals trying to find their own way to survive and doing pretty much exactly the same thing that you're doing, looting for supplies during the day, killing what they need to and then retreating at night.
