In 1989, LucasArts released their first adaptation of one of Lucasfilm's major franchises: "", based on the film of the same name. The game again upgraded the SCUMM engine's capabilities, but kept similar gameplay. The project was led by Ron Gilbert, David Fox and Noah Falstein; it was Fox's last adventure game for the company. A quotient point system, referred to as "Indy Quotient", allowed the player to overcome puzzles in several different ways, such as fighting a guard, sneaking past the guard, or convincing the guard to allow the player to pass.
