To safely navigate and explore the Aurora in Subnautica without suffering radiation damage, follow these comprehensive steps:

1. Prepare Essential Gear
– Radiation Suit: Equip this suit to protect against harmful radiation emitted from the crashed Aurora. This is imperative for survival as entering the area without it will result in health damage.
– Propulsion Cannon: This useful tool will help you clear away debris and any hostile creatures, such as cave crawlers, that may block your entry.
– Fire Extinguishers: Bring at least one or two to put out fires you may encounter inside the Aurora.
– Health Packs: Carrying these is advisable to heal yourself in case you sustain damage during your exploration.

2. Approach the Aurora Safely
– Location Awareness: The Aurora is situated in the Crash Zone, where dangerous creatures like Reaper Leviathans roam. To minimize encounters with these predators, steer clear of open waters.
– Safe Entry Path: Navigate towards the middle, shallow area near the crash site. This area is less frequented by Reapers. Keep close to the hull of the Aurora and aim for an entrance located on the right side, approximately halfway down the ship’s side.
– Avoid Risks: Refrain from drifting too far left or venturing out into the deeper waters, as this can provoke unwanted interactions with your foes.

3. Accessing the Entrance
– Identifying the Entry Point: Look for a marked ramp on the Aurora’s hull that serves as the entry point. You can either park your Seamoth here or swim to the door if your submersible is not available.
– Clearing the Path: Use the Propulsion Cannon to remove any cave crawlers obstructing the entrance. This will make your entry safer and easier.
– Story Progression: You’ll only be able to enter once the Aurora has undergone its scripted explosion, marking a key event in the game’s narrative.

4. Entering and Exploring the Aurora
– Suit Up: Ensure you are wearing your radiation suit before stepping inside to avoid radiation damage.
– Unlocking Key Areas: Use the following codes to access important sections of the ship:
– Cargo Bay Access: 1454
– Lab Access: 6483
– Robotics Bay: 6666
– Cabin No. 1: 1869
– Captain’s Quarters: 2679
– Laser Cutter: Bring this tool along to access locked doors. This will allow you to explore more of the ship’s interior.
– Repair Radiation Leak: Locate and fix the radiation leak inside the Aurora. This not only stops radiation exposure permanently but also unlocks achievements such as “Extinction Event Avoided.”

5. Additional Tips
– Navigation: Be mindful of your path inside the ship to prevent getting lost. Consider marking your route.
– Seamoth Storage: You can park your Seamoth in the Seamoth Bay, which is a strategic move for quick access if needed.
– Rewarding Exploration: Fully exploring the Aurora yields valuable blueprints and upgrades, including the Prawn Suit and upgrades for your Seamoth, essential for further adventures.

By meticulously preparing with the right gear, strategically approaching the ship, using proper entry methods, and effectively exploring its interiors, you can avoid radiation damage while unraveling the hidden treasures of the Aurora. Happy exploring!
