If you're getting stuck into the brand-new title by MachineGames, Indiana Jones and The Great Circle, you'll know by now that the game is chock full of puzzles, side quests, and other fun mysteries that you can solve if you're finding that you need some help solving the Secret of Secrets puzzle in Indiana Jones and The Great Circle.
How To Complete Secret of Secrets in Indiana Jones and The Great Circle
First and foremost, you'll get this little sidequest to go on if you explore thoroughly in the Sistine Chapel. To be able to get into the Sistine Chapel, you will need the Priest Disguise and Clerical Key, which you will receive from Antonio. Once you've got the key, you will be able to go through the Borgia Gardens and get into the Chapel through the main door. While the main objective is to complete the questline with Sister Catherine, there are some other little secrets that you can pick up in this area, including the Secret of Secrets Mystery.
Once you've spoken with Sister Catherine to get that quest started, you will find a door at the back of the room on the left. There will be a Mystery Note on the table for you to read, which will kickstart the Secret Of Secrets Mystery. This note will be regarding the 'original copy of the Secret Secretorum.' This is just one of the many mysteries you can solve in Indiana Jones and The Great Circle.
Compared to some of the other puzzles in the game, this one can be quite tricky. To be able to solve the puzzle, you'll need to focus on the two saints in the room, Saint Peter and Saint Paul, of which there are two statues. If you rotate them, you'll find symbols on the bottom of both statues. At first, this may not seem too important. However, if you check the desk near the safe, you'll find a Planetary Chart. The fourth symbol is missing; if you look at the base of the statue, you'll find this is the symbol that is missing on the chart.
Once you figure out that the numbers align with the symbols, it's a pretty easy puzzle to solve. This leaves you with the code for the safe.
The code is 4471.
This will allow you to open the safe, which will get you the Secret Secretorum, a Skill Book, and a note from Nicoletti, as well as 100 Adventure Points for completing the mystery.
