Regolith

Two hundred and fourteen days ago, the far-side lunar outpost Beacon-9 transmitted four seconds of empty carrier before falling silent. No distress call. No explanation. Just silence.

You command MU-7 CASSIOPEIA, a 900-kilogram, six-wheeled survey rover deployed into Anaxagoras Crater near the Moon's north pole. Your mission seems simple: survey the basin, restore a chain of communications relays, and reconnect the outpost with Earth. But one detail refuses to make sense—the mission dossier never explains what Beacon-9 was actually built to do.

Explore a rugged lunar landscape inspired by real geography, where towering crater walls block Earth's low position above the horizon, making the relay network essential for communication. Drive across ancient impact terrain, descend into shadowed regions, and search for clues left behind by a vanished expedition.

Use a ground-penetrating radar system that sends visible pulses through the lunar surface, revealing genuine subsurface objects hidden beneath the regolith. Every radar return has a real location and depth, requiring you to navigate to the site and decide which anomalies are worth investigating.

Deploy the rover's articulated robotic arm to manually drill core samples from the terrain. Recover minerals, ice, forgotten equipment, and mysterious artifacts while expanding a scientific codex that grows with every discovery. Each new entry reveals more about the crater, the expedition, and the secrets buried beneath the surface.

What begins as a routine geological survey slowly becomes an investigation into a mission deliberately omitted from the official record. Every repaired relay uncovers another piece of the story, every scan reveals something unexpected, and every core sample brings you closer to answering the question no one wanted you to ask:

What was Beacon-9 really built to find beneath the Moon?
