Frozen Planet is a Walking Sim made in Unity.

Set in the distant future on the remote world Gethenan.
Having been colonised and industrialised by humans, Gethenan has subsequently been depleted of all its resources and is undergoing rapid climate change. Extreme weather conditions plague the planet in its final days before the inevitable apocalypse. All colonists of the planet appear to have evacuated and few signs of humanity remain scattered around the Frozen wasteland left behind.
