Xevious is a vertical scrolling shooter arcade game by Namco, released in 1982.

The player uses an 8-way joystick to pilot a combat aircraft called a Solvalou, which is armed with a forward-firing Zapper for aerial targets and a Blaster which fires an unlimited supply of air-to-surface bombs for ground targets. The game, presumably set in Peru, was noted for the varied terrain below, which included forests, airstrips, bases, and mysterious Nazca Line-like drawings on the ground.

There are various aerial enemy aircraft which shoot relatively slow bullets, as well as (presumably unpiloted) fast-moving projectiles and exploding black spheres. Ground enemies are a combination of stationary bases and moving vehicles, most of which also fire slow bullets. Giant floating Andor Genesis motherships appear in certain areas; these are killed by knocking out their cores. These are considered one of the first level-bosses to be incorporated into a video game.

The game scrolls through 16 areas, looping back to Area 7 after Area 16. The Solvalou continually advances over varying terrain, and the boundaries between areas are marked only by dense forests being overflown. If the player dies, play normally resumes from the start of the area. If the player has completed at least 70% of the area before dying, play will begin at the start of the next area instead. As the Solvalou constantly flies forward, it is possible to advance without killing any enemies.
