Sub-Structure 17: White Knuckle Ascent

In White Knuckle Ascent, speed is your best friend—and gravity your worst enemy. Trapped in the depths of a massive underground megastructure, you’ll need sharp reflexes, clever inventory management, and a serious lack of fear of heights to make your way up through a labyrinth of decaying industrial zones, mutated flora, and things that definitely don’t want you to leave.

Master physics-driven, momentum-based movement to fling, swing, and claw your way up shifting terrain. Use tools wisely or get weighed down—because the wrong gear at the wrong time can drag you straight to your doom.

Each run is a fresh climb. Unlock strange augmentations, adapt to increasingly bizarre threats, and survive environments like the slime-slick Pipeworks or the creaking husks of the forgotten Habitation sector. And always—always—keep climbing. Something is down there. It knows you’re here. And it really doesn’t like quitters.

So tighten your grip. The only way out… is up.
