In addition to the main story quests, there are numerous secrets to uncover and mysteries to solve in Indiana Jones and the Great Circle. One such mystery is a quest called 'A Free Spirit,' which involves tracking down a missing cat called the Sinor Smushki. While it's probably not going to make the title of any grand Indiana Jones adventure, finding the elusive cat can be an enjoyable, unique quest to do while familiarizing yourself with the twists and turns of the Vatican City.
