X (1992 video game)

X is a 1992 science fiction-themed shoot 'em up video game developed by Argonaut Software and published by Mindscape for the Game Boy. The game is notable for being one of the first games to utilize polygonal 3D graphics on the Game Boy, achieved through custom programming techniques.

Players control a spacecraft, navigating through various levels presented in a pseudo-3D perspective. The objective involves shooting down enemy spacecraft and completing assigned missions, such as destroying specific targets or escorting friendly units. Gameplay features include the ability to strafe and to use a limited number of special weapons.

The game's story involves a future conflict between Earth and alien forces. Players assume the role of a pilot tasked with defending Earth from the alien invasion.

X received mixed reviews upon release. While praised for its technical achievement in rendering 3D graphics on the limited hardware of the Game Boy, the game was often criticized for its slow frame rate and limited gameplay depth. Despite its limitations, it is considered a significant technical demonstration for the platform. The game's soundtrack contributed to the atmosphere and helped to overcome some of the technical limitations.
