In the middle of a raging blizzard, Laura opens her eyes to find herself inside a mountain cabin. She was saved by Kimberly, one of the passengers of the wrecked plane. Ten days have passed since the crash but Laura can remember nothing, not even her name. The door of the cabin opens and one of the terrorists enters. While Kimberly and Laura stare in horror, he transforms into a hideous monster. He is not the only one. Other crash survivors and locals have mutated into terrifying monstrosities and attacked people. Is there anyway to survive this living nightmare? At present it is shrouded in mystery.
D-2 is a follow-up to D, though the two games are not directly connected to each other story-wise and also have significant differences in gameplay. D-2 combines a horror theme with shooter and role-playing elements. Exploring the vast snowy landscape and investigating the surroundings triggers extensive cutscenes that advance the narrative. The 3D engine allows free navigation around the world, though in-door locations have first-person navigation with limited movement. It is also possible to pilot a snowmobile, hunt for food, and capture photos.
