Deep Hole

Deep Hole is a 3D exploration game in which you guide Emma, a planetary investigator, through a deep vertical cave in search of unknown minerals. You overcome obstacles and descend through its layers, which extend beyond sight.

Explore the cave

A jetpack lets Emma reach places she cannot get to with a normal jump and land on unstable footing, but moving always carries a risk of falling. Assess the jetpack’s capabilities and find safe routes through the cave. You can collect items left inside to improve the jetpack, including increasing its uses and available actions, which expands where you can go.

The cave has four stages, each with a different atmosphere and new hazards or mechanisms. To open the door to the next stage, you must find the dropped card key needed to release its security lock. Search carefully so you do not leave it behind.

Drones and the base

Security drones patrol fixed routes inside the cave. When they find an intruder, they fire, so take care around them, especially on difficult scaffolding.

At the base’s elevator room, you can upgrade the jetpack and recover items. The elevator also lets you revisit stages you have already reached, giving you another chance to retrieve missed items or find routes you left unexplored.
