Xenon is a 1988 vertical scrolling shooter video game, the first developed by The Bitmap Brothers, and published by Melbourne House which was then owned by Mastertronic.

According to the game's instruction manual,[8] the player assumes the role of Darrian, a future space pilot in the Federation, currently at war with a mysterious and violent alien species called the Xenites that has lasted a decade.

In response to a mayday transmission from Captain Xod following an attack on his trading fleet, Darrian is forced to travel through Xenite-occupied territory in order to support.

Originally released for the Atari ST, Xenon was quickly ported to other platforms: the Amiga, Amstrad CPC, Commodore 64, DOS, MSX and ZX Spectrum.

[6] Writing in New Computer Express about the 1991 budget re-release, Stuart Campbell stated that although the graphics were "gorgeous" and had "never really been seen before", the gameplay was "simply tedious" and the game was the first to "turn 'style-over-content' into an artform".
