You are an industrial spy sent to Rursus Island, once the base of the UNDA research team – now abandoned, overgrown and full of mysteries. Use a compass and map to find your way, overcome various obstacles with a grappling hook and other tools, examine your findings and report everything to your management.

As you progress through the game, you’ll come across documents, audio recordings and clues in your surroundings that reveal the secret behind the UNDA team’s project – and the philosophical disagreements that may have led to its mysteriously abrupt closure. Fortunately, Rursus was left with plenty of clues, so it’s up to you to uncover all its secrets.

Solve over 25 wave-based physics puzzles: use reflections, interference and resonance to make your way through the island’s forgotten laboratories and ruins.

Every puzzle you solve brings you closer to uncovering the legacy of the UNDA project.
