Truxton

Taking place somewhere in space: an armada of Gidans, led by the evil Dogurava, is invading the planet Borogo aboard five gargantuan asteroids. After surviving an attack on an orbiting Borogo cargo barge, a pilot enters one remaining fighter and challenges the Gidans in a desperate attempt to quell the alien invasion and divert their asteroid fortresses in the process.

Truxton is a 1988 vertically scrolling, shoot 'em up arcade game developed by Toaplan, later ported to the Mega Drive (worldwide) and the PC Engine (Japan-only). Like many other scrolling shooters, the game is set in outer space, where the player takes control of a small spaceship across several planets. The game is played with an eight-way joystick and two buttons (a shot and a bomb button) through five large levels and their bosses (which then loop forever, at higher difficulties).
