Xenon is a 1988 vertical scrolling shooter computer game, developed by The Bitmap Brothers and published by Melbourne House which was then owned by Mastertronic. Xenon was followed in 1989 by Xenon 2: Megablast. The player assumes the role of Darrian, a future space pilot called into action by a mayday report from his superior on a nebula space station. As of late, the colonies of mankind have been under attack by mysterious and violent aliens called the Xenites and it is finally time for Darrian to engage them. Unlike most scrolling shooters, the player can move in any direction instead of straight up. The player craft has two modes, a flying plane and a ground tank. The transition between crafts can be initiated at almost any time during play (except during the mid- and end-of-level boss sections, as well as certain levels where a certain mode is forced), and the mode chosen depends on the nature of the threat the player faces. Destroying some enemies released power-ups the player could catch to enhance their ship.

The game of Astro Fighter consists of 4 waves and a refueling stage, which are then repeated with increasingly higher difficulty. The player's task is to eliminate the four successive waves of different types of attacking craft, while avoiding being hit by missiles and bombs, and then refuel by shooting the 'GS' ship before repeating the process. The player starts with 3 lives and receives a bonus life on reaching a score of 5000. 300 bonus points are received for shooting each 6 falling bombs and for 950 for hitting the GS ship accurately on the first shot. A very large bonus of 10,000 is given for getting through 4 waves and refueling by using exactly 2 shots more than the minimum needed. As the higher levels of Astro Fighter are difficult to survive consistently, even for the best players, the highest scores have been achieved by the achieving the 10,000 bonus deliberately.
