Nemesis

Nemesis (ネメシス Nemeshisu) is a 1990 shoot 'em up video game developed and published by Konami for the Game Boy, and part of the Gradius series, released for the Game Boy in 1990. Similar to Taito's Sagaia, this game uses a once-international title for an earlier game in the series to represent a mostly original project.
A sequel, Nemesis II, was released for the same platform in 1991. Both games were later re-released through the Konami GB Collection series, where they are titled Gradius and Gradius II instead.
