And so The Room 3 has come to an end. We've got the last pyramid. We pop it down on the table and we get the craftsman's key - and the door to the final room.

But wait! There are actually hidden endings to discover, and you get them by solving puzzles dotted around the hub world you have been using to access the main chapters in the game.

There are three to get. This guide covers the lost ending. Read on, to unlock this special finale. And no, it has nothing to do with smoke monsters.



Place the final pyramid on the table, and take the craftsman's key. Do not go through the door until you have…



Found the first mysterious artefact, which is found while working towards the release ending.



And found the second mysterious artefact, which you get while uncovering the escape ending.



Got both? Then it's time to go through the final door. Take a deep breath and step inside.



Place the craftsman's key on the top of this weird tent thing to crack it open.



Take this metal ring.



Place the metal ring on the front of the box. Spin it around until the hole opens. Go inside with your eyepiece.



Here, you need to make thee holes appear underneath the three pistons. To do this, spin the gold disc until the hole on the rear dial lines up with the piston. Use the brass handle to move the cog. Repeat this until all three holes are lined up, like above.

Press the button



Move this mirror to bounce the light around.



Take this mirror from a compartment on the table.



Place it here. Then move the first mirror back to its original position. You'll be taken to a hole - enter inside, using your eyepiece.



You now need to spin all the light beams until they are pointing at the red crystal, like above. Use one button to lock two of the beams in place, and the other to rotate the unlocked ones. It's all about getting them in sync.



Do not go through the train door. Place the artifacts into the two slots. Look at the one on the right, and find a screw on the back. Undo it with your screw driver, and pull the metal plate back to reveal a small lens.



Turn the metal dial on the other side and go inside. Solve the laser problem like before. Press the button on top and another wooden door will appear. Do not go through it!



Instead, go to the other artifact, spin the metal dial, and look through the hole with your eyepiece.



This one's easy. Spin the gem around, until you see a light beam coming out of the hole on the inside of the dial. Then, keep spinning the dial so light continuously shines on the green gem. When all the lights have let up on the side…



Press the button on top. Now, three lights are on the projection screen and instead of a door there's just a hole. Go on through to get the final ending: Lost.
