The plot closely follows, and expands upon, the film of
Indiana Jones and the Last Crusade. As the game begins, Indiana Jones has returned to his college, after reclaiming the
Cross of Coronado. He is approached by businessman Walter Donovan, who tells him about the
Holy Grail, and of the disappearance of Indy's father. Indy then travels to some of the places seen in the movie, such as
Venice and the catacombs, after meeting fellow archeologist Elsa Schneider. In the process he finds his father held captive in the Brunwald Castle, after passing through the mazelike corridors, fighting and avoiding guards. Then Elsa's double role is revealed when she steals the Grail Diary from Indy. After escaping, father and son pass through Berlin to reclaim the Diary and have a brief meeting with
Adolf Hitler. Then they reach an airport, from where they intend to seek the Valley of the Crescent Moon, by
Zeppelin or
biplane. There are many action scenes, involving punching, and the biplane sequence above
Europe, pursued by
Nazi planes. Several key elements of the film - such as the Brotherhood of the Grail, Indy's friend
Sallah, and the Venice water chase and the desert battle scenes (except for small hidden references) - were not included in the game. ==Development==
