UnderEarth

A subterranean puzzle-adventure game inspired by 90's era. There’s no handholding, no in-game menus, no messages from the devs, no tutorial. Some call it a marvel; some call it a good test for Steam's refund system. Certainly it’s not an easy game. Do you dare to puzzle? Just play savvy.

About



40 miles under the Earth's surface, a hazardous research and refinery facility has faulted. Attempts to raise communication with the installment have failed. The status of all fifteen workers stationed within the facility is unknown. Valvorta Industries, the controversial energy corporation responsible for the site, must maintain discretion. In response, Valvorta's BoD has elected to dispatch an engineering specialist to assess the situation. The mission is simple: recover information, restore output from the facility and rescue the workers trapped under earth.

Traversal through the facility will not be easy. The malfunctioning systems have made the descent near impossible. The high temperatures and the lack of breathable oxygen require the use of a specialized suit. You'll need a sharp eye to find any tools, lifts, documentation, and devices scattered across the facility, and a bright mind to put them to use. Extra attention must be paid to maintaining your suit's battery and air levels if you wish to survive. To make your mission easier, your suit provides a gauge on your current status, a log of any documents you find scattered about, magnetic boot attachments function for situational vertical and upside-down movement, and an instant connection to all terminals requiring rudimentary programming skills.

Find whatever information you can and piece together the events leading to the loss in communications. After that, it will be up to you to decide what needs to be done.
