It's got aspects I'd say were better than PA, like its combat you can have your arm shot off and every other part of your body hurt, and if you don't treat it it can get infected. Check out Quill18's playthrough on youtube.
Played this some months ago or longer. Was fun, but too short/small. When you built up your little colony (i build mine inside the caves you can cut out yourself, its way safer), the fun is pretty much gone.. map is small, enemies are weak and keep repeating the same tactics, making it dead easy to win . Hope it had some changes? Maybe I should redownload it sometime ^^
