Some stages have alternate routes depending on certain actions, such as whether players can clear a room of enemies before a non-playable character is killed by poisonous gas.After being defeated twice, Syndicate crime boss Mr. X has started a research company called RoboCy Corporation to act as a cover for his illegal activities.Axel quickly joins the task force, but Adam cannot make it due to his own assignments from within the police, and sends his younger brother, Eddie "Skate" Hunter instead.In the game's true ending, from which the events of Streets of Rage 4 follow, it is revealed that the real Chief Ivan Petrov was kidnapped and replaced with a duplicate.Once Dr. Dahm is apprehended and confesses to the government officials' kidnapping and replacement, the real Mr. X is revealed to be reduced to nothing but a brain in a laboratory capsule, controlling all the robots with his mind.Shiva, the martial artist who debuted in Streets of Rage 2 and newcomer Roo (Victy in the Japanese version) the kangaroo can also be accessed.The clothing of the three returning heroes (Axel, Blaze, and Sammy) was altered from their original colors seen in previous Streets of Rage games, the female enemy characters wore less-revealing outfits, and a sub-boss named "Ash", a gay stereotype, was removed from the English version (though he is still accessible in Streets of Rage 3 as a playable character via cheating and/or hacking).Another notable difference between the two games is the plot: The Japanese version of the story opens with a new explosive substance called "Raxine",[b] 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.On May 3, 2012, Streets of Rage 3 was released on Valve's Steam platform, both as a stand-alone game as well as part of the Sega Genesis Classics Pack 5.[18] The four reviewers of Electronic Gaming Monthly praised the new moves and larger levels, though two of them criticized that the soundtrack was well below Yuzo Koshiro's usual standard.[20] Diehard GameFan praised the gameplay and graphics, but took exception to the localization, saying it "neutered" an otherwise fine title, advising readers to import the Japanese version or pass it up entirely.In 2018, the Fact editor John Twells wrote: "When you're forced to hear snippets again and again, the atonal shards of algorithmic experimentation can be grating, but listening to the soundtrack as a whole is a different experience altogether: historical, challenging, innovative and artistic ..."[6] Twells described the soundtrack as Koshiro and Kawashima's "crowning achievement" and recommended it to all electronic music fans, even those uninterested in video games.[6] In a retrospective assessment, Mean Machines commented that the plot is lackluster and the music "takes some getting used to," but the visuals are colorful and beautiful, the levels are varied, and the challenge is more than sufficient.
