The games follows Indiana Jones in a adventure that is unrelated to any of the films. Set in 1932, Indiana Jones is on a mission to find Mazatec Power Key.
This leads him to the Topotzteco Pyramid in the Mexican Jungle, where he butts heads with Nazi forces under the command of Plebinheim, who is also after the Power Key.
It becomes a race to the finish, and the player must ensure that Indiana Jones finds the key before Plebinheim and his nazis.
This being a text adventure game, gameplay revolves around the player typing the actions of Jones at certain points throughout the game.
