The game is really hard if you don't know what to do. DO NOT spend a lot of time looking for guns. At first, you basically need to spend all of your time on finding survivors so you can find guns and repair your wall faster. They also help a lot with defense. Otherwise, you're gonna die fast.
Crazy alien tech I suppose. I don't quite get it myself! Thank you for the play and the comment! I appreciate it! Best, -Tim
