Indiana Jones and the Great Circle: The Monkey Business Mystery Guide

Monkey Business is another mystery in Indiana Jones and the Great Circle, which becomes available when examining strange warning posters in the Nazi camp in the southern region. If you don't know where to find the key to the equipment room, this guide will help you.

You can find several such posters, but to activate the mystery, it's enough to photograph just one. Once you do this, a marker will appear on the map indicating the area where the valuable item is located, namely the Equipment Room Key in the southern camp.

In front of you will be a tent with another puzzle, Counting Letters. Go around it on the right side, along the flooded road with several trucks. After the last vehicle, turn left and find the only narrow path leading to the ruins. Climb onto the ruins, and on the left, you can observe monkeys guarding the Nazis' belongings.

Read the tag next to the key and pick it up. It opens the grate on the second floor of the two-story building in the southern Nazi camp. Here you'll find the skill book Slugger II, a large amount of money, ammunition, and weapons.

If you have the Royal Army key, you can open the grate on the first floor and take the skill book Punch Out II, as well as some ammunition.
