Tail Gunner

Tail Gunner is a monochrome vector arcade game created by Vectorbeam in 1979. The premise of the game is that the player is the tailgunner of a large space ship. Enemy spacecraft attack the vessel in groups of three, and the player must aim a set of crosshairs and shoot the enemies before they slip past the player's cannons. Because of the game's viewpoint, instead of appearing to fly into the starfield, the stars move toward the left and center of the screen.
