Our take on UnderEarth

The defining detail is the absence of guidance: no tutorial, in-game menus, or developer messages are provided, leaving the player to inspect the facility, use its equipment, and reconstruct the events independently.

What is UnderEarth?

UnderEarth is a subterranean puzzle-adventure set 40 miles below Earth's surface, where a research and refinery facility has lost communication.

An engineering specialist must assess the site, recover information, restore facility output, and rescue fifteen workers whose status is unknown. Progress involves finding tools, lifts, documents, and devices scattered throughout the facility, then putting them to use. High temperatures and limited breathable oxygen make the suit's battery and air levels important to monitor. The suit displays current status, logs discovered documents, supports magnetic boots for vertical and upside-down movement, and connects to terminals requiring rudimentary programming skills. The game has no tutorial, in-game menus, or developer messages, leaving players to examine the facility and piece together what happened.
