About Fossilfuel

CAUTION: THIS GAME IS HARD AND FULL OF JUMP SCARES!
OPERATION FOSSILFUEL
Deep under the Great Sitkin Island in Alaska, you find yourself in the heart of one of the greatest scientific research facilities on Earth! Genetic researchers have bred mutant dinosaurs! But things go bad when the base is invaded by shadowy special forces, looking to steal the dino DNA. You grab your guns and your ammo and prepare for a fight...

JURASSIC SURVIVAL HORROR

At its core, Fossilfuel is a survival horror game. The player is trapped in a massive underground facility, Sierra, located in a remote location in Alaska. The player must use their head to find clues and solve puzzles to escape the facility.

MULTI ENDINGS

The game features several massive maps that the player can play in any way they want. Their decisions will decide the ending of the game. Once the player escapes the depths of Sierra, they are faced with the sprawling landscape that is, the Great Sitkin Island. The main story campaign will be a solid length of around 6 to 10 hours of gameplay depending on your skill level.

POWER TRIP

Experience a massive arsenal of weapons as you plow through a huge library of enemies. The game features a wide range of weapons that are not just traditional firearms, your standard FPS arsenal of Shotguns and rifles, but also weapons of science fiction! Weapons that can warp physics and crush your enemies' bones in seconds! The game runs on the power of the Unreal Engine, enabling crazy particle effects and physics as well as difficult enemy squad AI that tries to flank the player and calls for reinforcements as the situation dynamically calls for it. Enemy dinosaurs will use all their sense to track the player as well. A Velociraptor on the other side of the base is there...hunting you...always coming.

CHALLENGING ENEMIES

The game enemies also span into our Homosapien brothers. The enemy soldiers will call for reinforcements, radio ahead to comrades on the other side of the map to prep for the player, talk to each other, provide covering fire, flank manoeuvers, can spot dead comrades, watch and listen for the player to make sounds, and even spot the player clicking on their flashlight. These guys are tough but the player can cut them down with fun weapons like the black hole gun!

The Dinosaur AI is likewise very aggressive. Velociraptors have incredible eyesight and can hear every move you make. They tend to travel in pairs and love to perform flanking maneuvers as well. Raptors, however, are not the only baddies you will encounter. But you will have to play to find out!

Players are encouraged to record, make twitch, or youtube videos about Fossilfuel. Make sure you link to the game if you do so.

A FREE Demo featuring the terrifying introduction level is also on the Steam store.

I can't believe how many positive reviews this game got. Do not let the trailer fool you. This game is an absolute soulless cash grab that is barely functioning. There is no polish on this game at all. Even the achievements are glitched. DO NOT BUY.

The raptors have feathers, and that's cool. This is a pretty short game. Without dying you could probably finish it within an hour. There are some secrets/extra weapons you can find by going off of the normal path but you don't really need them. Dinosaur AI is wonky, from the land of jank. Sometimes they appear suddenly on top of you and kill you within one or two hits. That's ok, they're dinosaurs. Level design is mostly boxy corridors with little detail. Guns do what guns do. The inventory is limited and mostly an annoying factor that serves as a slight reason to be tactical about what you cram into your pockets. The human AI is dumber than the dinosaurs. Performance is fine most of the time, though the warehouse level seems to be terribly optimized. Voices are too low but the 80s style vibe to it makes it quite alright. In the end this oozes the same kind of enjoyment you get out of watching a B movie. It's the Carnosaur to Jurassic Park. It's arguable if one might find this to be a good experience or not, but it is chock-full of cool moments.

This is one of the most broken, buggy, and if possible unplaytested games to the point it makes a Bethesda game look like a seamless finished product.

Recommended Aug 8, 2026
This game is super fun. It's janky and definitely an indie game so if you're expecting super awesome animations and sound editing then idk what to tell you. There's just no good AAA dinosaur games like this one. I bought the bundle so I'm gonna go play the second one now. I played the demo and I thought it was fun and lots of improvements! The good: Fun campaign with a variety of different weapons you can use. Some actual scary moments that got me. Top notch voice acting 10/10. The bad: The classic unreal engine 5 lighting situation. Sometimes it was too dark but my flashlight was too bight. It kinda hurt my eyes.
