Players unlock chest code in Indiana Jones and the Great Circle through Cloud Atlas mystery

In "Indiana Jones and the Great Circle," players can start the "Cloud Atlas" mystery at the Nazi Meteorological Station in Gizeh, located near the Great Sphinx. The area is guarded by enemies. To solve the mystery, players must decode a note listing cloud types and times. The relevant times are 13, 9, 16, and 14, which correspond to specific cloud types in the logbook. The final chest code is 0609, derived from the cloud types Cirrus, Stratus, Cirrus, and Cumulonimbus. Opening the chest rewards players with cash and the Gizeh Medicine exploration book.
