About This Game
Raptor Isolation is a pure horror, single-player, experience where you must escape the infamous underground research base, Sierra, without a weapon while being hunted by a terrifying UtahRaptor!
Detailed Description
A major response to the original Fossilfuel, was that the players wanted more horror and less shooter gameplay. This has answered that call.
The Sierra Silo, the north wing of the base, deep in Alaskan Ice, houses more secrets for the player to uncover. Unlike in the main Fossilfuel game, this part of Sierra has no weapons. A Utah Raptor has gotten the scent of fresh meat and made its way into the base to hunt down survivors after the base loses power. You play as a lone employee trying to just find an exit, but lucky for you there is more than one as Raptor Isolation offers multiple endings.
Jurassic Cat and Mouse Horror

A massive Utah Raptor has your scent! Use your environment to your advantage, don't make noise, grab your headlamp, and use your smarts to escape!
Raptor Isolation takes place on a single large indoor map where the player must find clues and solves puzzles, in an old-school dino survival horror nightmare!

The Sierra Silo offers multiple hallways and rooms that the player can tackle in any order they want. This gameplay design allows for multiple routes and fits into the Cat and Mouse gameplay with the Utah Raptor.
