Oh, apparently it only lasts 20 nights and then ends... kind of lame - but there is a 2nd game so on to that, and the Dead Zone (since I already played Union City).
At first I found it kinda difficult to get past the first round just by myself, since you only have the pistol. Shooting them in the head helps, but it's not an insta-kill which sucks. It's a bit harsh, specifically since if your barrier isn't repaired enough, they will bust through in 2 seconds and you have VERY little space to move. So not wanting to break my mouse (lol, I was furiously clicking), I started over and then used a few more hours on finding a 2nd survivor. Which helped, a lot. Generally it's an okay game, I've made it 10 days so far and it's just meh, not too entertaining. I don't know when I'll quit playing it's just fun to see how far I can get.
Everything so far has worked decently in this game, and I've found it quite entertaining. It's definitely kept my attention. I had trouble with figuring out how to save the companion but worked my way around it. Overall decent game.
