two games is the plot: The Japanese version of the story opens with a new explosive substance called "Raxine", discovered by a character named Dr. Gilbert (who is revealed to be the true identity of Dr. Zan), which explodes in the city and kills thousands of people. At the same time, a military general named Ivan Petrov vanishes. It is later discovered that Mr. X orchestrated the general's disappearance and plans to use Raxine to start a global war. In the English version, all references to Raxine were removed, General Petrov was replaced by the city's Chief of Police, and the plot now involves a scheme to switch major city officials with robot clones in order to take control of the city. Another difference was if the player failed to save the general, the player has to head to what appears to be the White House. This too was changed in the English adaptation, where instead if the player failed to save the Chief, then the player has to head to City Hall, although the building depicting the City Hall is still clearly based on the White House. The bad ending sequence from the Japanese releases features a photo of a devastated city as text narrates the player's failure; this was removed in the Western releases and text scrolls upward on a black background. The credits were removed from the bad ending of the Western version (possibly to show that it was not the true ending), whereas in the Japanese version they still play. The game's overall difficulty was also altered for the English version, with the game's Normal setting being significantly more difficult than even the Japanese version's Hard setting. Also, the English version of the game cannot be completed on the Easy setting (it will end after Stage 5). Axel and Skate are noticeably absent from the European box art, while the new character Zan appears alongside Blaze. This is because the box art for the game was originally used as a magazine cover art that Sega of Europe bought later to be used. Another significant difference between versions is that the Special attacks consume less of the player's health in the English version. Soundtrack The game's soundtrack was composed by Yuzo Koshiro and Motohiro Kawashima, who had both worked on Streets of Rage 2, and features influences from Detroit's hard techno scene which was popular in Tokyo
