About the base game: 

Generation Zero is an atmospheric first-person guerilla tactical warfare game set in an alternative 1980s Sweden, in a region called Östertörn. The population of this peaceful rural setting vanished overnight, replaced by hostile machines who seem intent on killing anyone they meet. You set out into the vast open world, stumbling upon villages, bunkers, military installations and more, as you seek to uncover where these machines came from. During your travels, you find plenty of tools to help you in your encounters with this new enemy, including equipment to distract them and weapons to try your best to take them down. Additionally you have various skill trees that allow you to cater your abilities to better handle dangerous situations, and outfits to create your ultimate 80s fighter. If you ever feel that you need backup, you can always invite 1-3 friends to join you in your efforts.
