Here’s a short guide on how to complete the Mystery of the White Queen in Shadow of the Tomb Raider.
Shadow of the Tomb Raider: Mystery of the White Queen
Look at your artefacts and study the Enigmatic Clues. Upon reading the note, you will see that it instructs you to turn the globe to sit at 30 degrees North and 90 degrees East. Turn the globe using the two wheels until the numbers on the dial match this.
This will close the roof rafters and a beam of light will shine on the globe. Run to the ladder on the other side of the room and climb onto the ledge above. You will see a South American Healer statue and a Tyrannosaurus Rex skeleton.
The table on the left will have a letter from Dad to a construction company. Collect this, then turn about and run to the other side of the mezzanine where you will be prompted to use the Survival Instincts skill. You can interact with almost all the artefacts as you go around and hear an interesting snippet about each.
Beside the gold African tribal mask, there is another wheel. Turn this to open the bat wings ahead of you until the two red lights on its wings are visible. Then climb back down the ladder to the ground floor.
Directly ahead of you are chess pieces. Go to the single piece that’s in front of you and push it 2 spaces to the right. A red light will then shine on it and it will fix in place.
Next, go to the piece on the left of the board that’s directly in front of the shield. Push it one place to the left.
Now go to the piece that’s directly in front of the globe and push it one place to the right. Go to the one that was behind it, beside a piece highlighted red, and push it in front of the globe.
Return to the glowing red piece that was beside it and push it one space to the right, then go to the shield piece and push it into the space in front, then once to the left and then two spaces to the right where the red light is shining. The goal is to get the two shield knights into the light.
A wall will then disappear in front of you, revealing the white queen. She is trapped in a cage, so return to the globe and turn the wheel on the right to free her.
