X

X is a 1992 space combat simulation video game developed by Nintendo and Argonaut Software and published by Nintendo for the Game Boy. It was only released in Japan. The player assumes the role of the VIXIV starship as it must protect the planet Tetamus II from a mysterious race of aliens. Gameplay involves completing missions assigned by the "Training Academy Coach", ranging from protecting bases from enemy fire or delivering cargo to a certain area. Notable for being one of the few attempts at a 3D video game on the Game Boy alongside Faceball 2000, X was the creation of Dylan Cuthbert, who would later program the original Star Fox for the Super NES.
