Giza is the second large location in Indiana Jones and the Great Circle. As in the exploration of the Vatican, you will find locked boxes and closed safes, but there are quite a few of them here. In this guide, we have described all the available combinations that you will encounter along the way.
When players find themselves in Giza, the first story quest will be to find and collect stone slabs for Dr. Jones' new friend. However, one of the slabs is locked in a box with a combination lock. It can be found in the Nazi camp, in a large military tent. The code is written on a note nearby, on one of the tables among the equipment.
Exploring the southwestern part of Giza, you will come across Fritz's excavations, and at the top, there will be Professor Omar's tent. If you talk to him, you can get an additional quest, but we are not interested in that right now. A little higher on the hill, behind his tent, there is a locked box guarded by several fascists.
Note: There is nothing inside the box, as it needs to be opened to complete the side activity "Bright Future". Once you do this, run as fast as you can.
If you have not yet found the note that starts the side quest "Bright Future", immediately after opening the box, the quest will be completed, and you will receive adventure points.
Reaching the Nazi complex with Professor Voss's office in the story, you can find a locked safe on the first floor in the back room. The combination is different from the previous ones, as you need to enter five digits here. However, the correct code can be found one floor up if you study the note on the officer's desk. Inside, you will find a gold bar, an ancient relic, and a pistol (can be used as a secondary weapon or discarded).
You can easily miss this area if you are only following the main story. It is located northwest of the work area and is guarded by Fritz. Upon reaching here, study two notes that will be useful for obtaining the correct combination. To do this, you just need to match the state of the clouds by dates, guided by the reference book.
