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.

The Director General of Space Science Agency Dr. Venom was exiled to Planet Sard for a failed coup d'état. In the year 6665, he escapes and invades Planet Nemesis and the seven planets it controls with the help of Bacterion. The Nemesis High Council sends James Burton, ex-pilot of the Vic Viper, to pilot Metalion and attack Dr. Venom and the Bacterion invaders.

Gradius IV is the fourth arcade installment in a series of scrolling shooter video games developed by Konami Computer Entertainment Tokyo. It was preceded by Gradius III, released in 1989, although spinoffs had been released prior to it such as Gradius Gaiden. This title brings a considerable graphical upgrade, particularly with the use of colored lighting. In addition, there have been several additions and removals to the vaulted weapons system; specifically, the edit mode has been removed and an online ranking system was added.

Gradius Gaiden is a horizontal scrolling shooter set between Gradius III and Gradius IV that includes ships and weapons new to the series. It is the first Gradius-named title to incorporate 3D graphics

Gradius V is the fifth entry in Konami’s Gradius series, originally released for PlayStation 2. It introduces new mechanics while retaining core side-scrolling shooter gameplay. One notable addition is the ability to control the firing direction of "Options" (the yellow support pods) using the analog stick. While adjusting direction, the player’s ship remains stationary, adding tactical risk and challenge. The rest follows standard Gradius mechanics: avoid collisions and enemy fire while collecting power-up capsules to upgrade weapons. Gradius V was later released on PlayStation 3 as a PS2 Classic but has since been delisted and is no longer available for purchase.
