Hidden is the sixth main puzzle in the Eastern Wetlands area of The Talos Principle 2.

Puzzle elements

• Blue door
• Connector
• Emitter
• Inverter
• Pressure plate
• Purple barrier
• Receiver

Overview

When you enter the puzzle, you find yourself in a large room with a blue emitter on one side, a connector in front of you, a blue door in the middle of the room controlled by a blue receiver, a red receiver in a small alcove, a blue door to the left, and two purple barriers. The left blue door and the two purple barriers all lead to an L-shaped outer room, which has an inverter, a red receiver, and two pressure plates that control access to the progress wheel.

Hints

A basic hint:

[ hint ]

Since the name of the puzzle is Hidden, the first step of the puzzle is to try to activate the receiver in the main room that is the most hidden.

If you're struggling to get started:

[ hint ]

It is very important to remember that lasers can pass through purple barriers.

If you're wondering about the rules of how inverters work:

[ hint ]

In this puzzle, you may want to connect an inverter to more than one source of energy at the same time. If you do so, the inverter will give priority to the source that is directly an emitter, instead of pulling from a connector, if both are available.

If you're looking for an intermediate goal to make some progress:

[ hint ]

The blue door in the middle of the first room is rather inconvenient. Can you keep it open with just one inverter and nothing else? After that, can you keep it open with just something else, freeing up the inverter in the process?

If you're wondering what the eventual goal of the puzzle is:

[ hint ]

You have to find a way to move the connector to the outer room, so you can activate the pressure plates with one connector and one inverter. Equipment cannot be moved across purple barriers.

If you're looking for an obvious hint about the core mechanic of this puzzle:

[ hint ]

This puzzle emphasizes that you can use an inverter to satisfy a receiver using multiple sources. This means that after one of the sources connects, the other activates as well, and then the first source becomes free to use for the next stage of the puzzle.

Solution

[ solution ]

• 
  Take the connector, link it to the blue emitter, and place it far back in the open area.
• 
  Take the inverter, walk around the corridor, and link the emitter, the connector and the red receiver in the middle.
• 
  Take the connector, use it to link the emitter to the blue receiver by the open door and place it down far back in the open area.
• 
  Take the inverter, walk back to the other side of the corridor, and link the connector through the purple barrier, the emitter and the red receiver by the door.
• 
  Take the connector, bring it through the open door and place it down on the pressure plate.
• 
  Take the inverter and place it down on the pressure plate.
