Engage enemies in the sky and on the ground in Namco's vertical-scrolling shooter, Xevious. Your goal is to pilot a fighter ship named Solvalou to save Earth from an alien threat in control of 16 repeating areas. The eight-way joystick is used to guide your vessel and alter its speed, while individual "blaster" and "zapper" buttons are used to fire your ship's lasers and drop bombs, respectively. The action takes place from an overhead view of the planet as you travel across forests, streams, and more. Ground units such as tanks and buildings can be taken out by first positioning a crosshair target over the object and then pressing the zapper button. Avoid being hit by one of 14 sky-based and 12 land-based enemy types to survive. ~ Scott Alan Marriott, All Game Guide
