Sequels
A special version of Space Fever called SF-Hisplitter (SFハイスプリッター?), released the same year, features aliens double the width of the standard variety, which can either be destroyed completely or split into two smaller aliens depending on where they are shot. Not only the color version was colored, but also got the looks of its shelter blocks modified from the looks of the monochrome version's.
A sequel to Space Fever, known as Space Fever II (スペースフィーバーII?) was built into the Game Boy Camera and acted both as a means of selecting the other built-in games, and as a game in itself. Space Fever II deviates from the Space Invaders formula, featuring instead smaller waves of individual aliens and bosses based on faces of Nintendo staff as well as the "game face" photo taken by the player.
