complex 4546B

The planet is almost completely filled with water, although there are islands that literally float on the surface of the water, the depth under water can be very large, but due to the anomaly of the planet in water, a person can breathe for two minutes longer and swim to greater depths, the planet is several times larger than the Earth, and it is difficult to explore because it is filled with water, it has poles, like the Earth in the Arctic, and it is very cold there, the temperature there is below zero

Altera Corporation's research complex, a white, black, and blue technological multifunctional facility, is divided into several sections and located underwater at a height of 50-80 meters. One section of the complex is the technical section, where equipment is stored in garages for maintenance and modification. The second section is the research and development section, the largest, where they study flora and fauna of all sizes, minerals, and even human behavior underwater. The third section is the residential complex, housing staff quarters. These are typically single rooms equipped with a shower, toilet, bed, closet, desk, and window, as well as a mini-fridge for married couples. Larger rooms with double beds are also available, including the station captain's room and office, which is larger than all the others. It houses a library, a private aquarium, a planetary history hall, and a private kitchen. The residential complex includes a gym, a large cafeteria, libraries, lounges with living walls, aquariums, and historical rooms with portraits of explorers. Further on is the enclosure area, where creatures are kept for research.

The Shadow Leviathan is a giant predatory creature found in Subnautica: Below Zero.

Appearance The shadow leviathan has an elongated black body with smooth black skin and 37 pairs of small red spots running from the neck to the tip of the tail. Beneath each side of the row is a shorter row of seven round holes that extend just down the neck. The head consists of a triangular shield with three pairs of small black eyes, each with a large red ring in the center. A long vertical slit with a depression, covered with translucent, pointed, long, and blue "fangs," is the creature's mouth. Directly beneath the mouth is a transparent sac that stores recently consumed prey.

Seven pairs of large, clawed mandibles extend along the edge of the mouth. These graspers have "teeth" along the inner edge to better grip prey. The seven pairs of these appendages decrease in size as they approach the tail, to the point where the last three pairs are barely larger than a small spine. This gives the impression that these appendages once served as legs in a distant ancestor but have since been repurposed into their current form.

Propulsion is achieved by large fins on the tail of the shadow leviathan's body. This large fin extends approximately halfway along both the dorsal and ventral sides of the body. The pelvic fin has two smaller fins anterior and posterior. The tail ends in a red dot.

The Reaper Leviathan is a gigantic predatory lifeform belonging to the "Leviathan" class of fauna. It is extremely dangerous and can easily kill a player or disable their vehicle. It is the most dangerous enemy for vehicles, as it can destroy a Moth with one grapple or a CRAB suit with two grapples (usually it destroys in 3-4).

The creature's size allows it to be tracked using a scanning room. The Reaper has a long body, slightly longer than a Cyclops. Like some other predators on planet 4546B, it has two pairs of black eyes. On its head is a rather large bony crest, likely designed for ramming attacks during leviathan battles.

Floating Island) Above sea level. One of the few pieces of land, this island is kept afloat by Ancient Floats. Numerous unique plants grow here, and the only fauna are Cave Crawlers and Sky Rays. The first survivor base can be found here, along with their logs. A subordinate teleporter from Mountain Island is also located here. Underwater islands with a descent Underwater islands (Underwater Islands) 35 - 500 m. Chunks of earth torn from the soil by ancient floats. There are about 18 of them. There are caves inside the larger islands. A large number of bone sharks inhabit the area. There is also a lot of pitchblende and geysers on the seabed beneath the islands. Dunes with thermal springs Dunes (Dunes) 160 - 400 m A unique underwater desert. An ideal haven for sand sharks and reaper leviathans. The area is sparsely populated, but dangers abound. Bloody Seaweed with Mushrooms Bloody Seaweed Zone (Blood Kelp Zone) 150 - 630 m. This eerie deep-sea ocean arboretum may not look welcoming, but where else can you find such attractive and juicy bloody sacs of oil and a multitude of useful resources? The CRAB suit is great for harvesting pitchblende. Squidcrabs, Electric Eels, Endbringers, and Guardians also inhabit this area. A Spectral Leviathan inhabits the northern zone, but there are two entrances to the Lost River here. Sparse Coral Zone 1 Rare Reef (Sparse Reef) 40 - 310 m. A kingdom of small herbivorous fish. No predators. Plenty of vegetation. The surface of the biome is deep underwater, so drowning is very easy without special equipment. Big Reef95454 Big Reef (Grand Reef) 175 - 500 m. A dark, deep reef with Anchor Cocoons and dark water. The Phantom Leviathan also inhabits this biome. SeaTreaderPath1 (Sea Treader's Path) 170 - 360 m Named for the creatures that live there. These creatures are not very dangerous, and can even be used to obtain resources. Cliff Field near Capsule 8 Cliff Field

Safe Shoals375 Safe Shoals (Safe Shallows) 0 - 80 m. This is the spot where your escape pod lands. There are no predators here and plenty of edible fish. It's an ideal spot for building a starting base. There's a similar biome to the west of the main one. Kelp Forest - Night 9489 Kelp Forest (Kelp Forest) 25 - 150 m. Located right next to the Safe Shoals. It's the only place where giant Kelp grows, which has many useful applications. However, the area is unsafe; there are many Stalkers here. There's also a lot of scrap metal. Grassy plateau-pillars Grassy plateaus (Grassy Plateaus) 50 - 150 m. Sandy plains covered with red grass. Primary habitat for Sand Sharks. Biters and Reefspins can also be found here. There are many Moth fragments. An ideal place to build a base due to the abundance of flat surfaces. Mushroom Forest5496 Mushroom Forest (Mushroom Forest) 125-200 m. This forest consists of giant mushrooms. There are two such forests. The area is unsafe, with bone sharks occasionally encountered. Leviathan Reapers may occasionally swim near the borders of the Dunes in the western forest and near the border of the Crash Zone in the eastern forest. The eastern Mushroom Forest is the primary location of the Cyclops wreckage. ZoneKUSH593 Tuber bush zone (Bulb Zone, formerly Koosh Zone) 140 - 480 m. Bushes of unusual colors and shapes grow here, giving the biome its name. This biome is dangerous, with many Bone Sharks and Electric Eels. This biome also contains a large number of fragments of high-tech equipment and structures. Mountains Mountains (Mountains) 0 - 500 m Rocky elevations, the caves of which are home to a variety of life forms and contain many minerals. You may encounter reaper leviathans.

Transport is designed to facilitate player movement throughout the world and protect them from external threats. This category also includes objects that are not intended for direct player movement within the game world, but are considered vehicles in the global sense. Sea Glider: A portable device for accelerating movement. Due to its properties, it can be useful at any stage of the game. Moth: A small, versatile submarine. Adapted for any task. Oxygen is always on board, allowing you to explore the depths without fear of choking. Cyclops: A massive submarine. In essence, it is a real floating base, allowing you to place on board everything you need for comfortable exploration of the ocean depths. CRAB Suit Designed to protect or kill monsters and stay at great depths. Submarine "Shark" The largest submarine in the game, with a volume of about 3 cyclops, was not implemented due to its excessive size. Manta One of the unrealized types of transport, judging by its size, was planned as an early version of the cyclops, abandoned due to its excessive size. Draconis An unrealized type of transport, several times longer than the cyclops, but smaller in width and height, abandoned due to its excessive size.

Transport is designed to facilitate personnel movement around the world and protect them from external threats. This category also includes objects that are not intended for direct player movement within the game world, but rather serve as global means of transport.

Phantom Leviathan This creature approaches the size limit for viable organic life and belongs to the class of leviathans. It is a large, territorial, blue-blue creature, 107 meters long, with a unique, membranous, muscular, bioluminescent body, adapted to the depths and capable of bending into any position. Its hammer-shaped head is used for ramming, which does not injure the leviathan thanks to cartilaginous projections. It has six pairs of yellow eyes. Its mouth is small, but its powerful jaws are capable of tearing the flesh of any creature.

Planet 4546B is habitable, has normal oxygen levels, and is completely covered by water, with the exception of a few islands. It also contains a variety of biomes. The ocean depth in some areas can reach 3,000 meters or more, although in others it can be quite shallow. Aurora crashed into one of these areas, preventing it from sinking. 4546B is located on the outskirts of the Andromeda Galaxy at the far end of the Ariadne Arm. The planet is populated primarily by underwater life, with a variety of flora and fauna coexisting on it. The planet also has two moons, one of which is very close, causing frequent eclipses and somehow never leaving the sky, while the other's motion is imperceptible.
