Evaluation

Fossilfuel 2 launched on February 19, 2024 and received one free DLC — "Spy Games" — on June 19, 2024, which introduced a new open-world island map, a new playable character, and new achievements. That DLC represents the most substantive post-launch content addition to the game. Since the Spy Games DLC shipped, the developer has continued issuing bug fixes and smaller feature patches (Sandbox Mode, Cinema Mode, difficulty balance tweaks, a PS5 port in November 2024, and an engine update to Unreal Engine 5.4), but no new story content or major DLC has been announced for Fossilfuel 2. On January 21, 2026, DangerousBob announced that production had started on Fossilfuel 3, a full sequel, and the Steam page for that game went live. On May 15, 2026, a playable demo for Fossilfuel 3 was released, with the announcement thanking players for "supporting Fossilfuel 2 over the years" — language that signals the developer considers Fossilfuel 2's content journey to be concluded. There are no unreleased DLC listings, no announced future content for Fossilfuel 2, and no roadmap indicating anything further is planned. The developer's focus has clearly shifted to Fossilfuel 3.

About this game

Dinosaurs are here to eat you—feed them some lead!

Gameplay

In this thrilling first-person horror shooter, you will play Jack Allen, as he investigates the mysterious Alaskan Sierra Research Facility, now flooded with water, which has been overrun by deadly dinosaurs. You will have to put your skills to the test as you embark on a heart-pumping, 12-hour journey through flooded tunnels, puzzle-filled bunkers, and dark corners filled with jump scares. The base has a dynamic sandbox layout where players can revisit areas, get upgrades to their weapons, and clear sections to create safe zones by draining water in the flooded sections.

Use a massive arsenal of deadly weapons to bring the pain! Blast dinos apart in glorious gory detail all powered by Unreal Engine 5.

Much of the game takes place in flooded hallways and rooms. You will have to put on scuba gear and face off against monsters of the deep.

Fossilfuel 2 is filled with many puzzles to keep you on your feet. Explore the vast nonlinear base of the flooded Sierra Research Facility and face off against not only Dinosaurs but the environment as well.

Overview

Fossilfuel 2 is the highly-anticipated sequel to the indie game Fossilfuel, and it promises to deliver an experience like no other. With improved Unreal Engine 5 graphics, advanced AI, and a range of new weapons, you will have to use all your ingenuity and skill to survive in this Dino-infested facility.

Rich Lore

The Sierra Research Facility in Alaska was once a beacon of cutting-edge research and development, but the dinosaurs in the base escaped, and the base has been cut off from the mainland. Much of the base has been flooded with seawater. Jack Allen is part of an expedition sent out to investigate the Sierra disaster. But when their boat gets attacked by a Megalodon, the crew becomes shipwrecked on the shores of Sierra and must find a way to escape.

As a member of this team, you will delve into the dark secrets of the facility and uncover the truth behind the Dino outbreak. With a gripping narrative and heart-pumping action, Fossilfuel 2 will keep you on the edge of your seat from start to finish. The game has a heavy focus on underwater horror and has a massive cast of dinosaurs including Utahraptor and Spinosaurus.

Nonlinear Replay Value:

With a wide range of weapons and challenging AI, each encounter with the Dinosaurs will be unique. In Fossilfuel 2, no two playthroughs are the same. The game features multiple endings and player choices that change the course of the game. And with 12 hours of intense horror action, you will want to come back and play again and again to experience all the thrills this game has to offer. Get ready for a pulse-pounding adventure and uncover the truth at the Sierra Research Facility.

Sandbox Mode:

A Garrys mod-like sandbox can be unlocked for players to brandish their creativity. Spawn NPCs and watch them fight, or make a house with the block spawner, the possibilities are endless.
