"Lifeform readings in this region are sparse. The Aurora's radioactive fallout will have devastating effects on the alien ecosystem if not contained within the next 24 hours." ― PDA, Dialogue

The Crash Zone is the biome in which the Aurora crashed, hence its name. It is characterized by rocky slopes, mesas at the southern parts, and deep trenches covered with sand, and is littered with debris from the crashed spaceship. This biome is one of the eeriest biomes due to its open spaces, murky brown water, ominous wreckage, and the presence of nine Reaper Leviathans. The Crash Zone is the largest biome in Subnautica.

Main Crash Zone

The Main Crash Zone is located on the easternmost part of the map, surrounded by a Kelp Forest, Safe Shallows, the Bulb Zone, a Mushroom Forest, the Crag Field, and a Grassy Plateaus.

There is a large amount of dry land on the eastern side of the Aurora which has plenty of debris and Metal Salvage. Also, flocks of Skyrays populate this area.

The Crash Zone possesses a distinct sandy, murky tint of water, and is nearly devoid of Flora, though the western part that borders the Safe Shallows shares some of its flora. The biome makes up for this, however, with a wide variety of fauna, most of which being predatory - including the dangerous Reaper Leviathans. The harvesting nodes typically found in the area make this biome a good source for raw crafting materials.

A portion of the Bulb Zone goes into the Crash Zone, near Aurora's front section. This small area contains a good amount of Limestone and Sandstone Outcrops. It is guarded by a Reaper Leviathan.

The safest way to cross the Crash Zone is to follow the Safe Shallows as close as possible, then stick to the shallowest parts of the area. If attempting to enter the Aurora, it only takes a brief trip through deeper waters, although a Reaper Leviathan can frequently be found west of the entrance. The "landing" inside is shallow enough to provide some safety for embarking and disembarking. It requires a radiation suit and ideally should be done with a Seamoth, as there is a radiation field around the perimeter.

Story

In the cinematic trailer, it is revealed that Bart Torgal built himself a Seabase where the Aurora crashed. This reveals that the Crash Zone used to be a Safe Shallows-like biome, assuming that the cinematic trailer is canon. This seabase does not appear in game and was (if it existed) destroyed by the Aurora when it crashed.

The Crash Zone Trench

The Crash Zone Trench is the area behind the Aurora, which the latter unearthed during its descent. It is divided into two sections: The shallow, western trench, and the deeper and wider eastern trench.

The biome is extremely barren, only hosting one Fauna species and no Flora or Coral in the biome. Although, the eastern trench contains many more fragments and some Supply Crates with either Batteries or a First Aid Kit in them. The area bordering the Kelp Forest and Grassy Plateaus is relatively more shallow than the rest of the biome, being an easy way to obtain the valuable fragments in the biome.

There are a total of 3 Reaper Leviathans in this area. One in the shallow trench and two in the deeper one.

Crash Zone Mesas

The Crash Zone Mesas

The Crash Zone Mesas are located in the southern portion of the Crash Zone, near the Crag Field. The biome comprises six lively plateaus protruding above their surroundings, dotted amongst the barren dunes of the Crash Zone.

The Mesas harbor Flora not seen elsewhere in the Crash Zone, whether the lack of Flora elsewhere in the Crash Zone is due to the crash of the Aurora and subsequent irradiation of the area is unknown. A Reaper Leviathan patrols the area between Mesas two and three.
