Fossilfuel 2

Fossilfuel 2 is a first-person horror shooter set in the flooded Sierra Research Facility in Alaska, where escaped dinosaurs have cut the base off from the mainland. You play Jack Allen, part of an expedition sent to investigate the Sierra disaster. After a Megalodon attacks the crew’s boat, the expedition is shipwrecked on the facility’s shores and must find a way to escape while uncovering the truth behind the dinosaur outbreak.

Explore the facility

The nonlinear base has flooded tunnels, puzzle-filled bunkers and dark areas with jump scares. You revisit locations, solve puzzles, find weapon upgrades and drain water from flooded sections to clear them as safe zones. Much of the game takes place underwater, where scuba gear lets you face monsters of the deep as well as the dangers of the environment. The story takes about 12 hours and focuses heavily on underwater horror.

Fight the dinosaurs

You use a large arsenal of weapons against a varied cast of dinosaurs, including Utahraptor and Spinosaurus. The dinosaurs have challenging AI, and encounters can differ between playthroughs. Player choices affect the course of the game, which has multiple endings.

Sandbox mode

An unlockable sandbox mode lets you spawn NPCs and watch them fight, or build structures with a block spawner.
