Mysteries take up a large chunk of Indiana Jones and the Great Circle’s playthrough, and the Order of the Giants DLC also offers several unique mysteries that will grant you varying rewards. There are three Order of the Giants mysteries to solve, so keep reading to know how to solve them all in Indiana Jones and the Great Circle: Order of the Giants.
How To Solve A Collegial Mystery In Order of the Giants DLC
The code to the safe in the upper floors of Casina Pio IV is 1222. At the very start of the DLC, you get to explore Casina Pio IV. Within this area is a secret that is easily missable. After investigating the map in the main area, turn right and go up the stairs. Enter the rooms ahead to find a series of desks lined up under a religious painting. Turn around from those and investigate the desk to the right side of the doorway.

Pick up Federico’s Letter on the desk to start the Mystery. Turn around again and go back to the lined-up desks under the photo. Investigate the left side of the desks in the front row to pick up Alessandro’s Letter. This letter gives you the clues to figuring out the safe code, which we have mentioned above. Finally, head over to the safe on the far left side corner of the room and input the code to get the Hard Crust Adventure Book and two documents.
How To Solve A Tale of Wine Making In Indiana Jones: Order of the Giants

The order of the mural from clockwise is Plant > Harvest > Grow > Ferment > Process. After locating Ricci and going to the right side of the sewers, you will notice a breakable wall on your left. Use the sledgehammer nearby to break it up, alerting two enemies inside. Defeat them, then investigate the shelves to find a picture called Grow. This starts the mystery. Keep investigating the room to collect a Mural Note from a table.

To the left of the table, on the crates, is another picture called Harvest. Go right to the table after that and pick up the picture called Process. From where the two enemies were sitting, to the left is a little nook in the wall where you get the Ferment picture. Head back to the table, and right beside it is the mural. Pick up the Plant picture right on top and store it away for the time being.
Now, you need to arrange all the pictures in the correct slots, starting clockwise.
- Bottom left – Plant
- Left – Harvest
- Topmost – Grow
- Right middle – Ferment
- Far right – Process
Your reward will pop out of the drawer below, revealing the Perses Artifact.
How To Solve A Bull in the Sky Mystery in Indiana Jones and the Order of Giants DLC

Explore the Mithurium underground area to find a room that has the head of Saturn on the door. Interact with the door to start the mystery. Inside the new room, pick up the On Astrological Symbolism note on the right side of the desk. There are five bull statues to collect around this room, so go ahead and collect them all and bring them to the central section.

Now, you need to arrange all the bull statues according to weight and place them on the pressure plates in front of the pillars ahead. The one with three dots on the statue is the heaviest, followed by two statues having two dots, meaning these are of medium weight. And finally, you get two statues with one dot, which are the lightest. The order of statue placement from left to right is:
- First pressure plate: Medium
- Third pressure plate: Heavy
- Fourth pressure plate: Medium
- Sixth pressure plate: Small
- Seventh pressure plate: Small
Collect the Nymphus Artifact (one of the 7 Artifacts in the Indiana Jones DLC) from the wall on the right after that. Completing all three mysteries in Indiana Jones and the Order of Giants DLC will grant you the Depths of the Sky achievement.
