Indiana Jones and the Great Circle A Date to Remember code explained

The Indiana Jones and the Great Circle A Date to Remember code is needed to access a chest with a Blackshirt shipment inside, which itself helps you with your map to the Vatican - something that will be a great aid to you when exploring this region.

Unfortunately it's a confusing puzzle to say the least, not made any easier by the fact that players will be in enemy terrain and need the Indiana Jones Blackshirt uniform to go without being spotted. However, we can explain how to solve the Date to Remember code accordingly below, and how to open this secret chest.

Indiana Jones A Date to Remember code and chest location

The Indiana Jones A Date to Remember mystery kicks off in the Blackshirt tent area in the northwest corner of the central Belvedere Courtyard area of the Vatican. The southwestern tent holds a Shipment Report on the desk, which importantly tells you that Centurione de Luca “decoded the key for the wrong day” and therefore kicks off this shipment container mystery in Indiana Jones and the Great Circle.

Your map will then direct you to investigate the garden square in the Vatican’s Museum Wing, which can only be accessed via the door in this restricted Blackshirt tent area. However, you’ll find that the door – marked with a sign reading “Musei Vaticani” – is locked unless you’ve progressed the “A Nun in Trouble” fieldwork activity to the point where you need to follow Gina to the museum. She picks the lock on this Museum Wing entrance door, and there’s no other way in without her help.

Head across to the east side of the garden to find the lone Blackshirt tent with the chest inside and watch for the sleeping Blackshirt. To the left of the chest, you can grab a Secret Delivery Letter and a Calendar Page on the desk, and a Code Lookup Table in the drawer. Using those documents, you can enter the code 6380 to open the chest – the DICE code key is meant to correspond to Wednesday, making the code 4718, but de Luca set it for October 15, a Friday, so using this information and the Lookup Table, you get the real answer.

Inside the chest, you’ll find 10 Lira, Giovanni’s Letter, and a Vatican Medicine map guide, which reveals the locations of all 15 medicine bottles on the Vatican map. These medicine bottles can be handed over to Sister Valeria in exchange for Adventure Books that improve Indy’s stamina and health, which I highly recommend getting before heading off to Gizeh after you solve the Indiana Jones Fountain of Confession puzzle. For completing the mystery, you’ll get 100 Adventure Points too, of course.

There are plenty of these shorter mysteries all over the Vatican, and delving into each one is what makes this one of the best adventure games. Although, with so many side activities, you might also be wondering how long is Indiana Jones and the Great Circle?
