Deep Sea Adventure
A group of poor explorers hoping to get rich quick heads out to recover treasures from some undersea ruins. They're all rivals, but their budgets force them all to share a single rented submarine. In this rented submarine, they all have to share a single tank of air as well. If they don't get back to the sub before they run out of air, they'll drop all their treasure. Now it's time to see who can bring home the greatest riches!
