The apocalypse is coming and there's nothing you can do to stop it. How will you and yours meet the end is entirely up to you. You will primarily play a male protagonist that will progress from early adulthood to full adulthood. Your choices matter since the fate of those around you will be determined by your choices. Can they be spared? Some of them, all of them? This will be the adventure you experience but not just from one viewpoint. You can optionally see additional content from other characters perspectives via side story DLCs. Our family is on a collision course in ways none of them could ever imagine. The current content is focused on the prologue chapters as the main character makes decisions on who he will be when the end begins. These are important and affect the characters around you.
Important Note from the Dev: Everything is avoidable. If you don't like a certain 'genre' you will be warned in advance and it is entirely skippable/avoidable via menu choice. Great pains have been put in to ensure you get to experience the content you want and only the content you want.
