A surprisingly good Play Station 1 side-scrolling Shoot'Em Up from Square Soft (the same ones who made the gut-crushingly popular Final Fantasy series). The player takes the role of an anonymous fighter pilot sent by the moon nation Selene against Earth's forces, raiding its only city (called Sodom in Japanese version). Initially armed with nothing but a weak machine gun, the fighter can nevertheless grab weapons called gunpods from enemies, including plain old cannons and missile launchers as well as a lightning gun and energy sword. What follows is single small fighter cutting a huge swath through huge installations defended by endless numbers of aircraft and turrets.
