#3 D’Amico’s Office Safe| Chapter 6
Combination – 02/19/62
Code Document: Monthly Reminders
Unlike our previous safe, this one is part of the main story, so it is an unmissable one. This safe will be found in the D’Amico’s Office. The safe holds Giuseppe’s Printing Plates, a crucial item for the main story progression. You will find the code of the safe by reading the Monthly Reminders, found on the desk close to the safe.

And with that, you would have completed all the codes and the safe that each one opens in Mafia: The Old Country. The game is a relatively linear and tight experience of around 10-12 hours, hence there are not a lot of collectibles to search for and get like in other exploration-heavy and open world games.
