ALTERNATE UNIVERSE · RESTORE WHAT WAS LOST
SEARCH & RECOVERY · EARTH IS GONE
Earth was destroyed. What remains of it drifts in debris fields scattered across space — and buried in that noise, the last artifacts of our civilization are still faintly broadcasting.
Drag to sweep the scope — the scanner heats as you close in. Centre the signal and tap or click to capture it. Each recovery decodes a clue about the lost place it came from, and you can name it whenever you're ready — fewer clues, bigger score. Come back to the answer any time by tapping the clues. Recoveries refuel the clock.
Then warp to the alternate universe, where Earth still exists, and set each lost place back onto the new world.

Name it now, or keep hunting for more clues.
Going to your book ends this mission. The coins you have earned are yours to keep, but this run's score starts over. Real explorers study first, then fly.
