Subnautica 2 Aurora Exploration: Complete Ship Wreck Guide

The Aurora Shipwreck Overview

The Aurora is the massive crashed vessel whose wreckage dominates the horizon in Subnautica 2. It is the ship you arrived on, brought down by a mysterious weapon, and its remains hold some of the most valuable blueprints, story data, and resources in the game. Exploring the Aurora is a major mid-game objective that every player should undertake once properly equipped.

The wreck is enormous and partially submerged, with interior sections accessible through breaches in the hull. It is surrounded by a radiation zone caused by the damaged reactor, which means you cannot approach without a radiation suit. The interior is dark, flooded in places, and patrolled by cave crawlers and other scavengers that moved in after the crash. Bring lights, weapons, and repair tools.

The rewards justify the risk. Inside the Aurora you find blueprint fragments for the Seamoth, Prawn Suit, Cyclops, propulsion cannon, and other critical technology. You also find data terminals that reveal what happened to the ship and advance the main story. The Aurora is essentially a giant dungeon full of loot and lore.

• The Aurora requires a radiation suit to approach.
• It contains critical vehicle blueprints.
• Bring lights, weapons, and repair tools.
• Data terminals reveal the main story.

Entering the Aurora and Required Gear

Before you approach the Aurora, you must craft a radiation suit and all its components. Without it, you take continuous radiation damage and will die before reaching the hull. The suit blueprint is found by scanning fragments near the radiation zone perimeter or in early wrecks. Mine lead from galena ore to craft the suit components.

To enter the Aurora, pilot a Seamoth or swim to the wreck and locate the breached hull section. There is usually a visible opening near the midsection where the hull tore open on impact. Bring a propulsion cannon, because the interior is blocked by debris that you must move to proceed. A repair tool is essential for fixing doors and clearing paths. A laser cutter, if you have unlocked it, opens sealed doors that hide additional loot.

Bring a scanner and scan every fragment and data box you find. The Aurora contains fragments for nearly every major blueprint in the game, so a single thorough run can unlock multiple vehicles and tools. Carry a beacon to mark the entrance, because the interior is maze-like and easy to get lost in. Watch your oxygen, because flooded sections require you to hold your breath.

Exploring the Aurora Interior

The Aurora interior is a multi-level labyrinth of corridors, cargo bays, crew quarters, and engineering sections. Move methodically and scan everything. The layout is confusing, so drop beacons or use flares at junctions to mark your path back to the entrance. Many doors are sealed or blocked by debris, so use the propulsion cannon to clear paths and the repair tool to fix damaged door panels.

The cargo bay and drive room are the most important destinations. The cargo bay holds blueprint fragments for vehicles and tools. The drive room, deep in the ship's engineering section, contains the reactor core and a critical story objective: repairing the reactor leak to clear the radiation zone permanently. This requires a repair tool and following the in-game prompts to seal the core.

Cave crawlers infest the interior and will swarm you in dark sections. Use your survival knife or propulsion cannon to clear them. Watch for flooded sections where you must hold your breath -- plan your path so you are never far from an air pocket. The Prawn Suit bay, if accessible, often contains the fragments you need to build one.

Take your time and explore every room. The Aurora is packed with data downloads that tell the story of the crew's final hours, and these narrative details are some of the most compelling writing in the game. Do not rush through just for the loot; read the logs and absorb the atmosphere.

Repairing the Reactor and Clearing Radiation

One of the most important objectives in the Aurora is repairing the damaged reactor core. The reactor leak is the source of the radiation zone that surrounds the wreck, and sealing it permanently removes the radiation hazard from the area. This means you can return without a radiation suit and build bases nearby without contamination concerns.

To repair the reactor, navigate to the drive room deep in the ship's engineering section. The path is blocked by debris and flooded sections, so bring a propulsion cannon, repair tool, and laser cutter. Once you reach the reactor, follow the prompts to seal the leaks. The game guides you through the sequence, but it takes several minutes of work, so clear the area of crawlers first.

After the repair, the radiation zone gradually dissipates over the next in-game day or two. You can return to collect any loot you missed without the radiation suit, though the suit remains useful for other irradiated areas in the game. This single repair dramatically opens up the map, because the Aurora region becomes safe for permanent bases and exploration.

Completing the reactor repair also advances the main story, as the data terminals in the drive room reveal the cause of the crash and point you toward the next story objective. Read everything before you leave.

• Navigate to the drive room with full gear.
• Seal the reactor leaks to end radiation.
• The zone clears over the next day or two.
• Read all data terminals for story progression.
