About this game

Richat Structure is a strategic excavation simulator based in one of the most mysterious places on the planet. Lead a scientific expedition to the center of a ring-shaped structure in the Sahara Desert, the mysterious formation known as the Earth's bullseye. This place is visible from space; scientists study it, and conspiracy theorists discuss it. But no one has ever dug deep enough.

Build underground infrastructures, create mines and laboratories, extract resources and study anomalous finds. Upgrade equipment, direct work groups and make decisions that affect the progress of the expedition. Everything you find in the Richat Structure goes towards research- and the deeper you go, the less the answers look like science.

Key Features

  • Explore the depths. Dig mines, control the direction of excavations, build laboratories and research modules. You choose where to dig next and what resources to invest in the expedition.

  • Light is salvation. Darkness affects people: workers lose efficiency and sometimes even their sanity. Keep the lights on to maintain control and protect yourself from whatever may be lurking in the depths.

  • Anomalous finds. You won't just encounter common things like coal and clay- you'll also strange rock formations that defy classification. Send your findings to the lab to advance along the research tree.

  • Mental pressure. The deeper you dig, the more people change: they start speaking in riddles and acting strangely. The head of the expedition will have to choose between results and the safety of the team.

  • Profile selection. Archaeologist, biologist or miner- each character unlocks unique advantages and research approaches. Choose your style and adapt to the challenges of the expedition.

  • The final revelation. Apart from rare rocks, there are answers in the depths of the Richat Structure that can shatter your perception of the world. Unravel the mystery of the ancient formation: is it a natural phenomenon or something greater?
