You are the apparent sole survivor of a plane crash which sees you enter a living, breathing mysterious forest, lush with greenery and heavy woodland. The graphics are utterly sublime. The world has changing weather patterns, plants that grow and die. Tides that roll in and out with the day/night cycle. Below ground explore a vast network of caves and underground lakes. Above ground, trek to the summit of tall mountains across sprawling landscapes or bum around on the beach. However, it soon becomes apparent that you are not alone.
