Undersea 8

Undersea 8 is a walking simulator in which you explore an underwater ruin as part of a recruitment program for a shady company. The plan is to investigate the ruin, follow the company’s instructions and escape to claim a large prize: if you reach sea level, you have escaped safely.

Explore the ruin

Look for anomalies as you move through the underwater ruin. If you find one, descend; if you find none, ascend. Some anomalies may attack you.

Game modes

The game has two difficulty modes. Classic mode is the easier starting mode: find anomalies and escape. Normal mode adds oxygen management and photography, and unlocks after you clear Classic mode.
