CAUTION: THIS GAME IS HARD AND FULL OF JUMP SCARES!

Embark on OPERATION FOSSILFUEL, a thrilling survival horror experience set deep beneath Great Sitkin Island in Alaska! In this intense game, you'll find yourself at the heart of a cutting-edge scientific research facility overrun by mutant dinosaurs and invaded by shadowy special forces seeking to steal dino DNA. Grab your weapons and prepare for a desperate fight for survival!

Explore a Massive Underground Facility

As a survival horror game, Fossilfuel traps you in Sierra, a sprawling underground facility in remote Alaska. You'll need to use your wits to unravel clues, solve intricate puzzles, and uncover the truth behind the chaos if you want to escape. The game features large, detailed maps allowing for diverse exploration and strategic gameplay.

Multiple Endings Determined by Your Choices

Your decisions matter! Fossilfuel boasts multiple endings, influenced by the choices you make as you navigate the treacherous environments. Once you escape the depths of Sierra, you'll face the challenges of Great Sitkin Island. Expect a compelling main story campaign, offering roughly 6 to 10 hours of thrilling gameplay, depending on your skill.

Unleash Devastating Firepower

Experience a true power trip with a vast arsenal of weapons! Fossilfuel offers not just standard FPS firearms like shotguns and rifles, but also cutting edge science fiction weapons capable of warping physics and obliterating enemies in seconds! Powered by Unreal Engine, the game delivers stunning visuals, realistic physics, and challenging enemy AI that dynamically flanks and calls for reinforcements. Prepare to be hunted by intelligent, predatory dinosaurs, utilizing their senses to track your every move.

Face Challenging Human and Dinosaur Enemies

Prepare for intense combat against both human and dinosaur adversaries. Enemy soldiers strategically call for reinforcements, communicate with each other, provide covering fire, execute flanking maneuvers, and react to environmental cues. But the Dinosaur AI is equally threatening. Velociraptors, with their exceptional eyesight and hearing, hunt in packs, employing flanking tactics to corner you. But they are not the only prehistoric predators you'll encounter!
