As you explore the rich environments of Indiana Jones and the Great Circle, you’ll encounter numerous hidden challenges that test your puzzle-solving abilities. Among these cerebral tests, the Vatican City’s Father and Son puzzle stands out as particularly demanding. This comprehensive walkthrough provides everything needed to conquer this cryptographic challenge efficiently.

The Father and Son puzzle, which actually conceals a safe combination mechanism, becomes accessible upon completing a specific side mission chain. Your first crucial step involves establishing contact with Gina, who serves as your primary quest giver for this adventure. Properly initiating this sequence ensures you receive all necessary objectives and clues.

The mission titled A Nun in Trouble begins when Gina arranges a meeting at the iconic Sistine Chapel. This encounter triggers an extensive journey across Vatican City’s most recognizable landmarks. You’ll partner with Gina as she navigates through the elaborate Museum Wing before progressing to the historically significant Borgia Tower.

Reaching the Borgia Tower’s summit presents a combat encounter where you must overcome a Blackshirts enforcer to liberate Gina’s associate, Giuliana. Successfully completing this confrontation rewards you with Giuliana’s Key, an essential progression item. Be aware that this chamber also houses the Venus Figurine, counted among the prestigious Lost Artifacts of Europe collection.

With key in hand, retrace your path downward one level within Borgia Tower to the location where you previously employed your bullwhip for traversal. Here you’ll discover a secured entrance that yields to Giuliana’s Key, revealing a balcony area that serves as headquarters for a clandestine organization. This hidden space contains several valuable discoveries:

Your primary objective now shifts to evidence collection for deciphering the Father and Son cryptographic challenge in Indiana Jones and the Great Circle. Among the furniture compartments, you’ll discover a crucial document: an Italian Poem with specific letters highlighted: I-R-I-A-T-A-S-A.

This poetic clue functions as the input for a Polybius Square cipher, an encryption technique dating back to ancient Greece. The Polybius system transforms letters into numerical coordinates using a 5×5 grid where each character corresponds to a row-column pair. For optimal decryption efficiency, organize the letters into pairs: IR – IA – TA – SA.

Each letter pair converts to a two-digit number through the Polybius grid coordinates. The sequence IR becomes 42, IA translates to 43, TA converts to 44, and SA transforms to 45. These four numerical values collectively form the safe’s unlocking combination: 42-43-44-45.

Seasoned players can optimize their approach by preparing for the Borgia Tower combat encounter in advance. Ensure your health is maximized and whip techniques are mastered before ascending to the summit. The Blackshirts opponent employs aggressive melee attacks but leaves openings after combo sequences.

A common mistake involves mispairing the Italian Poem letters or attempting to decode them individually rather than as coordinated pairs. Always verify you have both the poem clue and Polybius Square diagram before attempting decryption.

For maximum efficiency, complete the Venus Figurine collection simultaneously with the puzzle solution to minimize backtracking. The entire side quest typically requires 25-35 minutes for completion, with the puzzle segment itself taking approximately 5-7 minutes when approached methodically.

The Throttle Adventure Book reward significantly enhances stealth gameplay approaches, allowing for silent takedowns that conserve ammunition and maintain covert operations. This aligns with broader Class Guide strategies that emphasize tactical flexibility in various combat scenarios.
