Buy Fossilfuel VR: Raptor Isolation PC key

Fossilfuel VR: Raptor Isolation is a VR horror game set in the Fossilfuel universe. You play as a lost Sierra security employee, unarmed and hunted by an intelligent, furious 300-pound Utah Raptor. Use items and your wits to find a way out of Sierra, an underground research lab in Alaska.

Explore Sierra

An EMP event has cut power to the vast underground base, and dinosaurs bred and experimented on there have escaped. Sierra is built around a main silo and side corridors containing clues and puzzles. You can tackle the game in any order as you search for a way to escape.

Evade the raptor

The Utah Raptor hunts you through the base. Sneak behind crates, avoid making noise and hold your breath as you try to stay out of its reach. The Utah Raptor is twice the size of a Velociraptor.

Story and endings
