The highly-anticipated first-person speed-climbing horror game, White Knuckle has a demo available for Steam Next Fest.

Developed by three-person indie studio, Dark Machine Games, the upcoming falling simulator climbing simulator will have you hanging by a thread, or rather your increasingly fatigued fingertips, as you try to escape a decrepit underground complex filled with all sorts of nightmares.

Climb, manage your inventory of gear, and avoid the hostile forces haunting SUB-STRUCTURE 17 and maybe you’ll live to see the light of day… Slip up on any of those and… well… if the fall doesn’t get ya, the encroaching ooze will.
