R-Type

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.
