Work from a huge ocean research station and dive from sunlit reefs to the 5,000-depth abyss in first person.

What you do

• Explore with up to 8 friends: ride submarines together, mark waypoints, scan, photograph and capture creatures as a team.
• Discover 60+ creatures: real sea life (whales, dolphins, sharks, rays, turtles, octopuses, squid, jellyfish, eels, the Japanese spider crab and more) and original fictional deep-sea monsters.
• Scan, observe, close in and capture with capsules; return them to the station aquarium.
• Fill a large research journal sorted by rarity, with your own photographs and a discovery percentage.
• Unlock eight submarines, capture capsules and station expansions; customise your sub.
• Dive through seven depth zones: 100, 200, 300, 400, 500, 1,000 and 5,000. The deeper you go, the darker and stranger it gets.
