-Gargantuan Leviathan Fossil-

This super-predator is 3 times the size of the Ghost Leviathan and Sea-Emperor, making them look like tiny babies. Skeletal-Remains can be found in the Lost River, with a Ghost Leviathan in the same area. According to the PDA, the massive fossilized remains are only 1/3rd of the full creature, indicating that this creature must have been around 1200–1500 meters long, and the remains are over 3,000,000 years old. Fortunately for the player, they are no longer living and are all Deceased.


PDA Info: The fossilized remains of an extinct super predator. Its sheer size would have prohibited it from entering such an enclosed space, suggesting the geography of the planet has shifted around it over time. A true apex predator.

• Dated at approximately three million years old.
  
• Rib cage measurements suggest the creature was eel-like in structure.
  
• Calculations suggest this is only the front third of the specimen.
  
• The remains now support a vibrant microcosm of life.

-Unknown Ancient Skeleton-

An unknown and unusual skeleton, belonging to an unknown Leviathan-Class Predator. The Head and Teeth of the animal are much larger than the Player. The player can swim inside the fossil through the missing teeth on its head. The Species of this massive creature is unknown, but what is known is that it is a carnivore and it appears to be Leviathan-Class.


PDA Info:

• The skull of a million year old armored carnivore. Projections suggest this lifeform would have been larger than any living specimen encountered on the planet.
  
• The oceans of 4546B must have been very different to support lifeforms of this size, with more open geography and many more lifeforms in the leviathan range.

-Alien Research Specimen Theta-

A very odd looking skeleton of a larger predator, sharing similar traits to that of the Sand Shark,
Boneshark, Biter and Blighter. It was unknown why this species died off but it was most likely assumed that the Kharra Bacterium killed off this species, and the one found in the Desease Facility was being tested on.


PDA Info: The skeletal remains of a vast predator, housed within an artificial habitat.

• The environment constructed to house the specimen suggests it was kept alive in containment for research purposes for months, or even years. Organic matter indicates the habitat once supported extensive plantlife, though it has since decayed. When the facility collapsed this specimen was either left to die, or killed on the spot.
  
  
• While it shares some skeletal traits with the biter and sandshark, including its distinctive double eye sockets, this fossilized specimen is significantly larger, and features unusual forearms rarely seen in aquatic species. This species has likely gone extinct in the past thousand years, and its evolutionary relatives have evolved almost beyond recognition.

-Deceased Sea Dragon-

This Sea Dragon has died from Head Trauma in an attack on the Desease Research Facility to get its eggs back. The Remains are around 1000 years old. The Aliens most likely took the Sea Dragons eggs to study them and watch them hatch to see if there is any way to hatch the Sea-Emperor eggs. The Sea Dragon attacked and destroyed the facility, but died shortly after. There is still 3 known Sea Dragons living in the Lava Zone.


PDA Info:The semi-intact skeletal structure of a leviathan class predator.

• There is clear evidence of massive physical trauma to the head. The damage is so severe it was likely the cause of death, and must have occurred somewhere nearby. Damage is consistent with a high speed collision with a solid object.
  
• Something in the environment has helped to preserve these remains, but calcium decay suggests an approximate time of death one thousand years ago. Bone growth suggests the creature was in the egg-laying stage of its lifecycle.

-Deceased Reaper Leviathan-

This Reaper Leviathan appears to have died because of a Sea Dragon wanting a meal. This Reaper has recently died in the past few months, meaning that one of the Sea Dragons killed it. The Reapers are not built for high tempature envoirments so the Sea Dragon had little of a fight.


PDA Info: Reapers are ill-suited to high temperature environments, suggesting this creature was forced down into the active lava zone by conditions outside its control.

• Trace muscle tissue remains on the bones, indicating the specimen died in recent months.
  
• Burns and other physical damage to the skeletal structure.
  
• Likely became prey for something bigger.

-Seamoth-

The Seamoth is a one-man Submarine/Spacecraft that can be used as a means of transportation in Subnautica. They are fast and if given upgrades, can be even better. The Seamoth can travel up to a depth of 900 meters with max upgrades.
PDA Line: The seamoth is a fast, safe mode of transport, but remember that swimming is good for your glutes and endorphin levels.

Crafting Recipe
The Seamoth is Crafted with:
-x1 Titanium ingot
-x1 Power Cell
-x2 Glass
-x1 Lubricant
-x1 Lead

-Prawn Suit-

The Prawn Suit is a one-man exosuit that is used to walk on the seabed in deep places. It can go up to 1700 meters down with max upgrades. The Prawn Suit is a much better choice for exploring dangerous zones like the Lava Zones and the Grand Reef as they are much heavily armored than a Seamoth.
PDA Line: It is normal when first piloting a Prawn suit to feel a sense of limitless power. Prawn operators receive weeks of training to counteract this phenomenon. You will have to make due with self-discipline.

Crafting Recipe
The Prawn is Crafted with:
-x2 Plasteel Ingot
-x2 Aerogel
-x1 Enameled Glass
-x2 Diamond
-x2 Lead

-Cyclops-

The Cyclops is a massive underwater submarine that is the largest vehicle the player can controll. It has internal storage, a docking bay for a smaller vehicle, and even (with upgrades) a Shield Generator and 3D Sonar, and many other devices. The Cyclops has 3 camera systems on the ship, and has 3 different speed levels (ahead slow, ahead standard and ahead flank). The Cyclops is suceptable to Leviathan-Class Predators but has many ways of fighting back.
PDA Line: Be advised: the Cyclops is designed to be operated by a three-person crew. Only experienced helms-people should attempt to pilot this vehicle solo.

Crafting Recipe
The Cyclops is crafted with:
-x3 Plasteel Ingot
-x3 Enameled Glass
-x3 Lead
-x1 Lubricant
-x1 Advanced Wiring Kit

-Neptune One Escape Rocket-

The Neptune Plans were developed at Alterra headquarters specifically to get you off 4546B and back to the nearest phase gate. This Vehicle is massive but cannot be piloted by the player. This vehicle is possibly the hardest to craft in the game. The player must construct 5 individual parts of the rocket. Once the player constructs the entire rocket, the player must get inside and activate all of the systems and then prepare a Time Capsule, and then they can leave.
PDA Line: Neptune One Rocket, online.

Crafting Recipe:
The Neptune One is crafted with:

Launch Platform:
-x4 Lead
-x2 Titanium Ingot
-x1 Computer Chip

Neptune Gantry:
-x1 Plasteel Ingot
-x1 Copper Wire
