About The Great Ocean

The Great Ocean is an ocean exploration game in which you dive in a high-tech submarine and use upgradeable tools to complete missions. You visit places including the Galapagos, Cozumel, the Arctic, the deep sea and a World War II shipwreck, encountering marine life and wrecks along the way.

Explore the ocean

The missions draw on real sunken submarines, battleship wrecks and planes, deep-sea creatures, and Caribbean coral reefs. You can swim alongside whales, sharks, dolphins and sea turtles, including the blue whale. The game presents information about this threatened ocean world and over 100 species.

Levels change between visits, with new quests or fish species to discover. Completing missions contributes to ocean protection efforts, and the game supports the work of the Whale and Dolphin Conservation (WDC), a charity dedicated to protecting whales and dolphins. Proceeds also support PlanetPlay's certified Green Projects; in 2024, Demi Lovato, David Hasselhoff and Joe Jonas joined the diving experience.

Use your tools

You use different tools to carry out tasks: cut trapped whales free or remove turtles from entanglements with a laser, scan species for details, repair subsea cables with a welder, and collect pieces of the nuclear submarine Kursk with a beam grabber. A tutorial level introduces movement and the ROV's tools.

The mothership

On the mothership, you can view scientific presentations and interactive data at a holographic table. A “Maximal Comfort” setting is available to help with nausea in VR.
