Burai Fighter Deluxe

About

The player starts out with a relatively weak cannon but can upgrade to ring, laser, and missile weapons, which are much more powerful. The player can also choose from three difficulty settings: Eagle, Albatross, and Ace; but the fourth difficulty setting, Ultimate, must be unlocked. One proceeds by controlling the character in 8 directions and can shoot in a different direction from the direction he is looking.
