White Knuckle is a tense first-person, high-speed climbing game developed by Dark Machine Games. Set in the eerie depths of SUB-STRUCTURE 17, players must navigate their way through a crumbling underground megastructure using precise movement mechanics and quick reflexes. The game combines action and adventure elements, forcing players to navigate through different regions such as the Silo, Pipelines, and Dwellings, each presenting unique obstacles and threats. As you progress, you will encounter strange life forms and sinister creatures, while a mysterious, increasingly aggressive presence will constantly stalk you. Resource management is crucial, as players must carefully manage their inventory to avoid becoming encumbered and falling backwards. With its harsh atmosphere and demanding gameplay, White Knuckle offers a thrilling experience where every step can mean the difference between survival and a fatal plunge into the abyss below.
