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.

No-one likes a and loser. And no-one comes more universally despised than Xenites. For a thousand years they have been plotting revenge for their humiliating defeat in the last Galactic Conflict. Now the very fabric of time is in danger. The Xenites have planted five Time Bombs through history. Only you can save the day - not to mention the Universe. The last time you met it was a playground scrap. This time it is war.

A top-down, vertical-scrolling shooter from the late 80s.

In this shoot 'em up the player has to fight off four assault waves consisting of different enemy types until he reaches a huge UFO. After destroying the protective plates guarding the UFO's pilot in his cockpit the player can kill the pilot. The game starts anew with harder enemies.

Contra: Legacy of War is a 3D action game produced by Konami and developed by Appaloosa Interactive that was originally released in 1996 for the PlayStation and Sega Saturn. It was the first of two Contra games that were externally developed by Appaloosa, followed by C: The Contra Adventure in 1998. The game marks the series' jump to three-dimensional graphics and controversial changes in gameplay. Legacy of War was released packaged with a pair of 3D anaglyph glasses, which the game supported. Legacy of War bears the distinction for being the first console game in the series to retain both the Contra title and human characters during its release in Europe and Australia (where the console series has been known as Probotector from the first NES game and up until Contra: Hard Corps). The game was scheduled to be released in Japan as well, but was canceled.
