Gradius – The Interstellar Assault, released as Nemesis II: The Return of the Hero in Europe, and Nemesis II in Japan, is the second Game Boy game in the Gradius series. The game was later ported to the Konami GB Collection series of Super Game Boy and Game Boy Color compilations; it can be found in the Japanese Vol. 3 and the European Vol. 4.

Like Gradius before it, these versions were renamed Gradius II for the Japanese Vol. 3 and Gradius II: The Return of the Hero for the European Vol. 4. Gradius: The Interstellar Assault retains the traditional horizontal scrolling gameplay from the Gradius series. Once again the player takes control of the Vic Viper and flies through five different stages destroying Bacterion’s army. The game retains the traditional power-up bar from the original Gradius.

The player can speed-up multiple times, use missiles, shoot double firepower or lasers, use several options at a time and use the classic shield (although it is referred to as a forcefield). However, before each game is started or continued, the player is given a “Weapon Select” screen. Here the player can choose between one of three settings for the missiles, double firepower, and lasers.
