Pressing the "Power-Up" button will award the player the power-up that is highlighted on the power meter. The types of power-ups that can be obtained throughout the course of the game are selected at the "Select Weapon Array" and "Weapon Edit" menus before starting. The cursor cycles through the following power-ups in order: "Speed Up", "Missile", "Double", "Laser", "Multiple", and "Shield". With the "Speed Up" power-up, players are able to increase speeds of their ships; with the "Missile" power-up, players can launch air-to-surface missiles to destroy ground targets; and with the "Double" power-up, players can fire an additional gun that fires in another direction other than forward. The "Laser" power-up allows players to fire enemy-piercing lasers, the "Force Field" power-up gives players three additional hits before being destroyed, and "Multiple" power-up gives players clones (also called "Options") that shadow their movements and mimic their firing. A new feature in "Gradius V" gives players the ability to control their "Multiples" with the push of a button, depending on which weaponry was selected before starting the game. By pressing a button, players can freeze their Multiples in place, cause them to rotate around the Vic Viper, control the direction of their fire, or spread them out above and below the ship. It was modified from the similar system used in "Gradius NEO", a mobile phone game released months before this game. In the year 8010, the planet Gradius is once again invaded by the alien Bacterians, who assemble a large-scale assault force to destroy its enemies. The Vic Viper T-301 and its unnamed pilot is deployed to rout the Bacterians. During the battle, a large Bacterian spacecraft comes out of a space-time warp and attempts a kamikaze attack on Gradius, but a second Vic Viper follows it and tells the pilot that they need to destroy the spacecraft's twin cores simultaneously. This is performed successfully, and the Vic Viper leaves to continue the offensive in other locations. Near the end of the game, the Vic Viper encounters a spacecraft in a Bacterian facility and is unable to destroy it. A study of the spacecraft reveals that it is exactly the same one that tried to smash into Gradius. Now realizing that the other Vic Viper's pilot was himself from the future, he activates a space-time portal and travels to the past in order to aid in its destruction alongside his past self.
