Terracrest

Terracrest is about returning to Mine 41-A to retrieve research data left behind during an evacuation. You pilot an old prototype mining drill that was made functional shortly before the mission, and must keep the vessel operational as you explore the underground mine.

Explore the mine

You navigate with echo-cast, a form of echolocation that projects a digital representation of what lies ahead. A scanner helps you find energy signatures to replenish your power and locate outposts. When you reach an outpost, use the Short Ranged Receiver (S.R.R.) to download the data left there.

Maintain your vessel

The mining vessel leaks air, so you need to cycle oxygen back into it through the air lock. Its breaker can also begin to fail; when it hums, crawl into the engine room to repair it. Managing power consumption, breathable air and the breaker is part of keeping the vessel running.

Mission and endings

You can leave the assigned mission to uncover secrets the company wants hidden. Doing so can unlock four alternative endings, and each ending unlocks different extras. These range from freely roaming the main menu to playing a fish-themed arcade game.

Development history

Terracrest grew from Power Driller, a 2017 game made in Scratch about navigating a maze of breakable and unbreakable boxes to reach a power block without running out of power. A 3D reboot followed in 2023 for the GDevelop 3D jam. After a break, that version was remade and expanded, first as Power Driller 2, then Project Earthquake, and finally Terracrest.
