Xevious © 1982 Namco.
Xevious (pronounced 'zeevious') is a vertically-scrolling shoot-em-up in which the player pilots the heavily-armed 'Solvalou' combat ship and must destroy the evil Xevious forces trying to take over the planet. The Solvalou is equipped with two weapon systems; the forwards-firing "air zapper" for shooting air-based enemies and 'blaster bombs', for destroying ground-based enemies. To enable accurate targetting of the air-to-ground blaster bombs, a white and blue targeting indicator is situated in front of the Solvalou. This flashes when an enemy is in its sights.
Enemy craft appear in a number of different guises; from the standard variety that arrive in large numbers but shoot slow-moving projectiles, to exploding black spheres that shoot projectiles at high speed. There are also rotating shields that cannot be destroyed and must be carefully avoided. Ground enemies are a combination of both stationary bases and moving vehicles, most of which fire slow-moving projectiles. A gigantic, floating fortress called 'Andor Genesis' appears in certain areas; this is defeated by knocking out its core.
Xevious is divided into 16 different areas, each separated by an area of forest. If the player dies before less than 70% of an area has been completed, play restarts at the beginning of the same area; should a life be lost AFTER 70% of an area has been completed, however, play restarts at the beginning of the next area. After Area 16 has been completed, the game loops back to Area 7.
The game becomes progressively more difficult as the player becomes more skilled - once the player does well at destroying a certain enemy type, a more advanced enemy type will replace it. This can be reverted by destroying flashing-red 'Zolback' radars found on the ground, which will cause the more advanced enemies to be replaced with weaker ones.

Xevious was released in December 1982 in Japan.
Xevious is not the world's first vertically-scrolling shoot-em-up but has a huge and lasting influence on the genre.
Xevious was the first game to use pre-rendered graphics and, among its countless innovations, was also the first vertical shoot-em-up that allowed accurate targeting of both airborne and ground-based enemies. The graphics were hugely revolutionary for their time; the sprites were rendered with remarkable clarity and detail due to the game's clever use of colors and shades as well as palette-shifting. Xevious was also the first game to feature 'hidden characters', which, being hidden, are not mentioned in the game's instructions but can be revealed by performing a secret maneuver. Among these was the 'special flag', which gave the player an extra life. This feature was carried over to a number of subsequent Namco games.
While Xevious enjoyed limited popularity in North America, the game was a huge cult hit in Japan, and to this day is considered one of the greatest video games of all time. Popular Japanese musicians, Haruomi Hosono (Yellow Magic Orchestra) and Kuwata Keisuke (Southern All Stars) were known to be fans of the game, and the former produced an album of music from Namco video games, with Xevious as its centerpiece. A follow-up 12-inch single featured in its liner notes an entire science-fiction short story by Endoh, set in the world of Xevious, with even included a rudimentary fictional language.
At one point in the game, the Solvalou flies over the Nazca lines. The Nazca Lines are geoglyphs (drawings on the ground) located in the Nazca Desert; a high, arid plateau that stretches 37 miles between the towns of Nazca and Palpa, situated in the Pampa region. They were created during the Nazca occupation of the area, between 200 BC and 600 AD.
The graphic ROMs contain several additional enemies which don't actually appear in gameplay including a silver-grey Galaxian flagship. These enemies do appear in the game-play of Super Xevious which uses the same graphics data as Xevious.
The highest score possible is 9,999,990, at which point the game terminates abnormally and resets. Some time before this score is reached, the game starts to award extra ships on every blaster shot fired.
Marco Borroni holds the official record for this game with 7,009,560 points (!) on August 16, 1984.
The background is actually one large 1024x2048 image. Each of the 16 game areas is a 224x2048 strip starting at a different horizontal offset in the image.
