Nemesis is the first portable game in the Gradius series, released for the Game Boy in 1990. This is not the same game as the European and Japanese Nemesis on the MSX. The game has five stages and plays similarly to previous Gradius games. It was released in North America and Japan. The game was later included in the compilation Konami GB Collection Vol. 1 for Game Boy and Game Boy Color, where it is titled Gradius.
This game allows the player to select the stage and the number of available extra lives from the very start. This is also the only game in the series to use the European name of the Gradius series, "Nemesis", internationally. The sequel to this game is Gradius: The Interstellar Assault, also know as Nemesis II: Return of the Hero.
After a fierce battle over the Planet Gradius, the Bacterian Army that broke in front of the super space-time fighter Vic Viper seemed to have turned into cosmic dust and perished. However, their existence was not extinct. Their space invasion plan was now aimed at Planet Nemesis so they launched an invasion attack to take possession of the beautiful planet. The Vic Viper picks a faint S.O.S and immediately flies to Nemesis!
