Fossilfuel 2 is a first-person dinosaur-themed survival horror shooter set in a mysterious, flooded underground research facility in Alaska. You play as Jack Allen, part of an expedition investigating the now-isolated Sierra Research Facility—a once cutting-edge center for scientific development that has now become the stage for terrifying events. After a vicious Megalodon attack leaves the crew shipwrecked, you must navigate through 12 hours of heart-pounding action in an environment overrun by deadly dinosaurs such as Utahraptor and Spinosaurus.
