Mario Is Missing! is a 1993 educational game developed and published by The Software Toolworks for MS-DOS, Nintendo Entertainment System, and Super Nintendo Entertainment System, later released on Macintosh in 1994. The player controls Luigi, who must travel around the world to find and return stolen treasures as part of a quest to find his brother, Mario, who has been captured by Bowser. Mario Is Missing!, part of a series of educational Mario games, marked Luigi's first starring role in a video game (although he was the main character of the 1990 Game Watch game Luigi's Hammer Toss), which would not occur again until 2001, when Luigi's Mansion was released for the GameCube. Gameplay Mario Is Missing! is an educational game. The computer version is a point-and-click adventure while the NES and SNES have platform game elements. In the game, Bowser, king of the Koopas, has relocated from the Mushroom Kingdom to the real world where he has set up his headquarters in an Antarctic castle. Bowser plans to steal the Earth's treasures with the use of the Passcode-Operated Remote Transportation and Larceny System (PORTALS) which allows his Koopas to teleport anywhere in the world. Bowser intends to sell the treasures to pay for enough hairdryers so he can melt the ice of Antarctica. He captures Mario to prevent him from foiling the plan and it is up to Mario's brother Luigi to save him. The player controls Luigi throughout the game. At the beginning of the game, Luigi and dinosaur Yoshi are at Bowser's castle and Luigi has access to the PORTALS, allowing him to teleport to cities where the Koopas are operating. The player can view a map of the city that Luigi is in, as well as a map of the world that is known as the Globulator. The player can use the Globulator to control Yoshi's movements across the world, which is necessary to reunite Yoshi with Luigi. The player has access to a computer that keeps track of various clues learned throughout the game, including information gained from speaking to people in the cities Luigi visits and pamphlets regarding the landmarks that have had something stolen from them. Notable locations in the game include Cairo, New York City, Mexico City, Paris, Buenos Aires and Tokyo. Missing artifacts include Big Ben, the Mona Lisa, the Great Sphinx of Giza, and strangely enough, King Kong. Upon arriving
