Polyaris

Polyaris is a single-player, first-person survival skiing game set in a post-nuclear, procedurally generated Arctic world. Survive the cold, ski through icy wastelands, find essential resources, fight enemies, and uncover the mystery of why you are the last one alive. The main character is an engineer working in a remote northern outpost, living somewhere in the far north on the border of Norway and Russia. The game begins with the onset of a nuclear war. Since the protagonist is in the distant north, he is not directly affected, but he loses contact with the outside world.
