ビックバイパー
The player pilots the starfighter Vic Viper starfighter to battle the onslaughts of the Bacterion Empire. There are a total of ten levels in the game, with stage 4 being something of a bonus level; here, the player controls the Vic Viper in a third-person perspective and must avoid colliding with walls. Though the level is completely devoid of any enemies, free floating power-ups are scattered throughout. There are also two hidden levels that are based on the early sections of "Gradius" and "Salamander". The game contains the familiar weapons, level layouts, and enemies that have become trademarks of the series.
