List of Gradius media

Gradius is a video game series created by Japanese game designer Machiguchi Hiroyasu and published by Konami. The series debuted in arcades with Gradius in March 1985, renamed Nemesis for international versions. Games in the series have been released for several platforms, including arcade hardware, home video game consoles, handheld systems and mobile phones. The Gradius franchise consists of 16 games, including spin-offs, home conversions and compilations, as well as other forms of media such as toys, manga, soundtrack albums and literature. The series has been seen by critics as important and influential for the shoot'em up genre, inspiring games such as R-Type, Thunder Force and Darius, as well as setting the template for horizontal-scrolling shooters as a whole. It is Konami's most successful shooter series and one of the company's core franchises.

Gameplay in the series remains relatively consistent throughout each installment: players assume the role of a starship called the Vic Viper in its efforts to vanquish the Bacterian army before they destroy the planet Gradius. Being a horizontal-scrolling shooter, the player must destroy enemies and avoid both them and their projectiles. Some enemies leave behind power capsules when destroyed, which can be used to select one of seven different weapons on the player's "power meter", and collecting more of them will give access to stronger, more durable weapons. Common elements throughout the series include enemy "Moai" statues, additional playable ships, and boss rush segments.
