About This Game

THE ULTIMATE CAVING SIMULATOR

Experience dry and wet caving as you descend into tight squeezes, massive chambers, and uncharted depths, upgrading your gear and equipment where preparation, navigation, and nerves decide how far you make it underground.

EXPLORE ALONE OR WITH FRIENDS

Venture underground Solo or Together in 4-player co-op to tackle dangerous cave systems. Coordinate ropes when rigging vertical pitches, navigate flooded passages, squeeze through tight restrictions, and search for safe routes deeper into the unknown. Every expedition demands teamwork, planning, and communication if you want to make it back to the surface.

GEAR UP FOR THE DESCENT

In order to bottom the caves, preparation is everything. Upgrade and customize your caving equipment before each expedition:

  • Helmets & headlamps

  • Climbing ropes, anchors & SRT equipment

  • Overalls and clothing suitable for different temperatures

  • Scuba gear for flooded passages

  • Shovels, winches, and more for digging and clearing blocked passages

  • And much more!

The deeper you go, the more equipment you need ... and every decision matters.
