Embark with up to 6 players on an underwater adventure to uncover treasures, shipwrecks, resources, or forgotten creatures. You’ll also almost certainly find death.

Print your gear, assign roles, and craft a careful strategy. Or just charge in headfirst—whatever floats your submarine.

Even if you think you know the area, you’ll probably be in for a nasty surprise.

Your teammates have gone silent, and a menacing shadow looms. Muster all your courage—and throw it as a distraction while you make a break for it.

If you’re still alive, dive back in deeper.
