It's fun... with friends. I gotta say though, there's some flaws with it that simply didn't make it enjoyable for me as a whole. Whilst I know this game actively is under development, I feel like the fact that it still needs modding for me to enjoy it completely says something.

Guns are strong, but at the same time underpowered. Getting infected sucks. Bleeding also sucks. You get attacked by more than one zombie at once? That sucks too. Hordes are even worse! I get at a certain point you're supposed to have shelter and all that good stuff, but it's not really fun to sit around.

It's a vicious cycle. You set up your base, you fortify it, you go out and get something you need, you fortify it, you go out and get something you need... There's also no ending. You cannot win, if it weren't clear with the opening beginning with "This is how you died".
