This classic shooter, originally ported to the NES in August 1988, is a spin-off of the seminal Gradius series.
Pilot the Vic Viper through six stages of intense action, alternating between horizontally and vertically scrolling environments, and take on wave after wave of enemies. Destroy particular enemies throughout the game (which takes place within the body of an enormous alien) to release power-up capsules and equip your ship with your choice of more powerful weapons, extra speed and shields.
Utilize the power-ups carefully, though, as a fearsome guardian lurks at the end of each stage and won't be easily defeated. You can go it alone or bring along a friend to take on the challenge simultaneously. Do you have what it takes to save your planet?
