Subnautica is an adventure game set on an alien ocean planet. A huge, open world full of wonders and dangers awaits you! Immerse yourself in a cavernous underwater world You are shipwrecked on an alien water planet, and the only way down is to get down. The oceans of Subnautika are very diverse - from sun-filled, shallow coral reefs, through treacherous, deep ocean trenches, lava fields, to underwater rivers illuminated by bioluminescence. Manage your air resources as you explore kelp forests, highlands, reefs, and twisted cave systems. Water is teeming with life: some are helpful, but most are dangerous. Collect, Craft, Survive After your Rescue Capsule lands hard, the clock starts counting down. Find sources of drinking water and food, take care of the development of equipment necessary for exploration. Collect resources from the ocean around you. Create knives, light sources, snorkeling equipment, as well as underwater scooters. Venture deeper and farther to find rarer resources that allow you to craft more advanced items. Build Underwater BasesBuild bases on the ocean floor. Plan the layout and select the components. As the pressure increases with depth, keep in mind the tightness of the hull. Use your base to store resources, park vehicles, as well as replenish your air supply as you explore the vast ocean. Unravel the mysteryWhat happened on this planet? Many clues indicate that something is wrong. What caused the accident? What causes the plague of marine life? Who built the mysterious structures scattered across the ocean? Will you find a way to get off the planet safe and sound? Break the food chainThe ocean is full of life: use the ecosystem to your advantage. Lure and outwit a dangerous creature with a fresh fish, or just swim as fast as you can to avoid the jaws of the ubiquitous predators. Deal with the PressureBuild an Underwater Adaptive Aqua Diving Robot, or PRAWN suit for short, and explore the extreme depths. Modify the suit by adding: mining drills, torpedo tubes, gravity cannons, climbing kits and much more. Fear the nightWhen the sun goes down, predators come out to feed. The ocean is merciless to those who find themselves unprepared in the darkness. Areas that are safe during the day become treacherous during the night – but they also discover beauty that those who fear the dark will never see. Go below the bottomCave systems stretch beneath the ocean floor – from dark, claustrophobic passageways to grottoes illuminated by bioluminescent life forms. Explore the world below the ocean floor, but be careful with oxygen levels and avoid the dangers lurking in the dark.
