In the darkest reaches of infinite space, pure evil lies in wait ... The Dark Forces led by the god of destruction, Bacterian, prepare to launch a massive onslaught against the planet Gradius. Possessing unstoppable power, the Dark Forces threaten to plunge the Universe into total war and complete annihilation. Their invasion force smashes the Gradius defenses, and the surrounding planets soon fall like dominoes. Now Bacterian's evil grasp reaches for the heart of the resistance...planet Gradius itself... To counter the oncoming threat the United Gradius World Forces gather all their fighter craft. Half of them form a defensive net - the other half a strike team. But they are badly outnumbered and The Dark Forces easily tear through their thin frontline. No fighters survive the slaughter.... In a last gasp move, the United Gradius World Forces send out two fighters, previously considered too dangerous for combat missions: The InterDimensional VIC VIPER fighters. The Fighters take off for the heart of darkness to join the fray that will decide the fate of the Universe...

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.

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.

Nemesis is an Action game, developed by Konami and published by Ultra, which was released in Japan in 1990.

The Director General of Space Science Agency Dr. Venom was exiled to Planet Sard for a failed coup d'état.

The Nemesis High Council sends James Burton, ex-pilot of the Vic Viper, to pilot Metalion and attack Dr. Venom and the Bacterion invaders.

Vulcan Venture (also known as Gradius II: Gofer no Yabo) is a side-scrolling shoot ’em up developed by Konami and released in arcades in 1988. Players control the Vic Viper spacecraft as it battles the Bacterion Empire, now led by Gofer. The game builds on the original Gradius by retaining the power-up bar system while introducing selectable weapon configurations and expanded abilities such as different missiles, double, and laser options. It also incorporates elements from Salamander (Life Force) and introduces a stage focused entirely on consecutive boss encounters.

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.

Andro Dunos is a horizontally scrolling shoot 'em up arcade game released by Visco in 1992 for the SNK Neo-Geo MVS. The player controls a futuristic fighter spacecraft with different weapon settings that you can switch between, and shoot enemies, collect power-ups, and defeat bosses to advance levels.

R-Type is set in the 22nd century, and the player flies a futuristic fighter craft called the R-9a "Arrowhead", named for its shape, and because it is the ninth model in the 'R' series of fighter craft (but it is the first of the series to actually be used in combat; the previous models were all prototypes). The mission is to 'blast off and strike the evil Bydo Empire'. The R- in the series title originally stood for "ray", as in a ray of light. It was a reference to the many different types of ray-like weapons in the first R-Type. his was later retconned in R-Type Final to refer specifically to the production code as well as a term of endearment for the player fighter craft, the "Round Canopy". The original R-Type was well received by most gaming critics. However, it was also infamous for its relentless difficulty. It earned 7th place in IGN's Top 10 most difficult games to beat. The gameplay of R-Type is noticeably distinct among shoot 'em ups. Invariably the player will lose, not because of an inequality in firepower, but because of the design of the levels themselves. There is usually a 'correct' way to get through a level, but players must learn these by experience - i.e. by losing and restarting from earlier in the level. The game innovated with its weapon system compared to contemporary shooters, featuring a chargeable shot (beam-meter), and detachable 'force' pod; levels were designed to require different tactics and ideal weapons (air-air, diagonal, or air-ground laser).
