White Knuckle is a first person speed climbing game.

Ascend through the guts of SUB-STRUCTURE 17 using precision movement mechanics. Sharp reflexes and resource management will take you to the highest peaks under ten thousand meters of concrete and decay.

Just don't lose your grip, it's an eternity below you.

You're not alone down here. Strange life flourishes far underground, and darker things haunt the halls where humans used to work. Something oozes from deep in the world, following you, growing angrier, faster, and it won't let up.

Travel through different regions with unique threats and gameplay challenges during your attempted escape of the underground megastructure. From the deep dry storage of the Silos, through the putrid sewers of the Pipeworks, to the haunted piers of Habitation, each new area will require adaptation to new obstacles and denizens.

Manage your inventory or become encumbered and fall to your death. Failure to grab what you need from your bag in time is a sure way to die.
