Storyline

It’s December of 1989, in the desolate forests and hills of the Swedish countryside. A month has passed since the population vanished overnight, and you have spent this time exploring the grim open world alone and with friends, sticking to the shadows to scavenge for equipment and weapons in your attempt to stay alive. All the while, you’ve identified the mastermind behind the events leading up to the attack and it has now led you to Himfjäll. This unexplored island off the east coast might hold more answers, and perhaps something even more valuable - other survivors.
