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.

You're not alone down here. Strange life flourishes far underground, and darker things haunt these halls. Something oozes from the depths– following you, growing angrier… and it won't let up.
