Gradius III and IV - Fukkatsu no Shinwa [Konami the Best] Japan

Players take control of the InterDimensional Vic Viper ship in a solitary attempt to repel an overwhelming invasion force from the planet Bacterian. The rest of the United Gradius World Forces were destroyed prior to Gradius III because they were 'badly outnumbered.' So now you're alone, in an attempt to destroy all who dare stand in your way.
