X

X (エックス), is an early three-dimensional first-person shooter-type video game software released for the Game Boy only in Japan on May 29, 1992. The game was published by Nintendo and was developed by Argonaut Software (who later became best known for being the developers of the original Star Fox title for the SNES). The gameplay and graphics are similar to Atari's 1980 arcade game, Battlezone; however, it is considered by several people as the earliest 3D Game Boy game. It was also the first game Kazumi Totaka composed music for.
