Arcade game:Xevious

Released in 1982, Xevious was developed by Namco and licensed to Atari for release in the U.S. As one of the earliest vertical scrolling games, Xevious was highly sophisticated for its time. Game designer Masanobu Endoh even programmed the game to automatically adjust to the player's skill level. If a skilled player is easily crushing the opposing forces, the game increases in difficulty by dispatching more enemies.
In Xevious, players fly a Solvalou Super Spacecraft over varied scenery of oceans, deserts, and forests. The objective of the game is to destroy the alien forces- the Xevious- that have invaded Earth. Players must avoid enemy attacks from the ground and sky. Enemy bases, tanks, and underground bunkers shoot up at the Solvalou Super Spacecraft flying overhead. Meanwhile, enemy air fleets and the Andor Genesis Mothership provide danger in the skies. Occasional crystal snowstorms can also damage the player's spacecraft. Players can earn bonus points by uncovering secret markers (a popular feature in games thereafter).
Although a cult hit in Japan, Xevious had more limited popularity in the U.S. Nonetheless, Xevious was ported to a number of home game and computer systems of its time, and can still be found on many classic arcade game collections for systems today.
Xevious marked a departure from the common space setting with a flat black background. Instead, Xevious provided players with a rich, colorful world to explore. The gameplay and graphics of Xevious represent the transformation video games were undergoing; the days of a black screen and simple gameplay were coming to a close.
