Indiana Jones and the Last Crusade

As in the movie, the player's quest is to find the Holy Grail. En route, the player must find the Cross of Coronado, the Knight of the First Crusade's Shield and Henry Jones Sr.'s Grail Diary.

In the Game Gear and Master System versions, the timer counts down very fast so thorough exploration isn't a thing here. Plus that this version suffers from a bug that makes one of the hourglasses to not properly appear at level 5.
