Indiana Jones and the Great Circle: Walkthrough & Boss Guide

Indiana Jones and the Great Circle is set in 1937, between Raiders of the Lost Ark and The Last Crusade. It opens at Marshall College, where a giant named Locus breaks in, steals a cat mummy and knocks Indy unconscious. Indy notices a symbol on Locus's medallion that resembles one used by the Vatican Secret Archive, which sends him to Vatican City.

Vatican City is controlled by Mussolini and the Blackshirts, who are working with the Nazi archaeologist and occultist Emmerich Voss. Indy teams up with the reporter Ginetta “Gina” Lombardi, who is investigating Voss over the disappearance of her sister Laura. They learn that the Nephilim Order, a tribe of giants, has secretly worked for the Catholic Church to protect the Great Circle, and that the cat mummy holds a special stone. Voss steals the Order's stones and escapes by zeppelin, and Indy and Gina stow away on it.

At a Nazi dig in Gizeh, Indy learns that the Order has worked with the Egyptians for thousands of years, longer than with the Church. Voss takes the stone from the Idol of Ra and leaves Indy for dead in the desert; Gina rescues him.

Indy and Gina learn that the third stone transported a Nazi battleship from South America to the Himalayas. They find Laura frozen to death, and Indy is captured by the Nazi colonel Viktor Gantz. Gina throws a grenade that frees Indy and sends the battleship skidding down the mountain, and Indy uses the third stone to open a portal.

The portal leads to Shanghai during the Japanese invasion. Gantz dies there, and Indy and Gina hijack a Japanese fighter plane.

Indy and Gina reach the nearest Great Circle ruin. Locus confronts them and warns that the Great Circle's secret must never come to light, but Indy ignores him. Voss attacks while Indy collects the stone, and Gina is captured during the escape.

Indy realizes he values Gina more than the stones, and Locus helps him track Voss. At the Ziggurat of Ur, Locus summons the Nephilim Order to attack the Nazis and Indy rescues Gina. Ignoring Locus's warnings, they then find Noah's Ark. Voss captures them, explains that the Great Circle is tied to flood myths and to the power granted to Noah, and activates it, triggering another flood. Indy and Voss brawl, and Voss is killed by the Ark's unstable power. Locus teleports the Ark away through a portal, preventing the flood.
