Known as Assault Suits Valken in Japan, Cybernator is a 2D mech game developed by Masaya and released in 1992 for the Super Nintendo Entertainment System. The second entry in the series, it is a prequel to a game called Target Earth, that came out on the Sega Mega Drive / Genesis two years before this. Cybernator was localized and published overseas by Konami. The plot of the game sees Jake Brain pilot a giant mech who fights in a war that has engulfed the entire world. Taking place in the future, when Earth's fossil fuels have begun to dwindle, there is a massive conflict taking place all over the earth for control of these resources, as well as for territorial rights on the moon.
The game was produced by Toshiro Tsuchida who went on to work on the game Front Mission, a tactical role-playing game developed by G-Craft and published by Squaresoft. Its soundtrack was composed by Masanao Akahori which was later rearranged / released as a CD and the original Japanese release of the game even featured artwork by the famous Satoshi Urushihara. The content in the Japanese version of Cybernator was the subject of quite a bit of censorship during its localization however. For example, the Japanese version features written dialog accompanied by a likeness of the speaker, but these likenesses are missing in the localized versions. There is also a scene absent in which the president of the enemy forces realizes that his nation has been defeated and takes his own life. Strangely however, there are a few human enemy deaths that remain unaltered in the game and receive no censorship when they are killed.
