All Item Effects & Synergies

Follow this guide to uncover all secrets in Tales of the Neon Sea, including missable files, achievements, and key decisions that impact the story.

This section of the guide covers the 'Uncovering Buried Secrets' part of Tales of the Neon Sea. It details how to find three missable Image & Text Files and three Achievements. Be aware that two of the Achievements are mutually exclusive and require reloading a save file to obtain both.

Rescuing Charles

Begin by inspecting the files on the whiteboard to find the 'The End (5/8) - Robot Puppets' File. Interact with the large life support device and then the computer to its right. Read all files on the PC desktop, paying close attention to the diagram on the far right, as it's a clue for a code.

Next, interact with the chain console control panel. Use the first three buttons to adjust the height of the colored lamps to match the diagram from the computer. The correct sequence is: press the purple/orange button twice, the yellow/green button once, and the blue button twice. This will reveal stairs leading down.

In the Secret Corridor, examine the courier clothes if desired, then enter the doorway at the far left. In the secret room, examine the diary. Continue left and inspect the Beta Type Consciousness Transmission Device to find the 'The End (6/8) - The Research Information of Consciousness Transmission Device' File.

Speak with Charles. Grab the Crowbar from the far right of the room and use it on Charles's holding cell door. After a scene, you will unlock the 'The Story of Rescuing the White Mustache' Trophy/Achievement.

Decision Time

You will be presented with two questions. The first answer has no impact, but the second choice determines which of two Achievements you will unlock. You cannot get both in one playthrough without reloading.

• Turn it off: Unlocks 'The Liberation' Trophy/Achievement. This choice also unlocks the 'The End (7/8) - The History Between Edward and Luna' File.
• Keep it on: Unlocks 'The Benevolence' Trophy/Achievement. This choice does NOT unlock the aforementioned File.

After making your choice, you can skip ahead to 'The Final Confrontation'.

The Final Confrontation

Regardless of your choice, you will need to return to the secret room where you rescued Charles. Head down the stairs when ready, as there is no turning back.
