The world of Streets of Rage 2 is quite a rough one to deal with. While Axel, Blaze and the rest of the gang are quite capable at taking on this world, even they need a helping hand from time to time. Both Batman and Superman answer the call to assist cleaning up Streets of Rage 2. As many reading this already know, both Batman and Superman are no strangers to brawler games so it is a natural fit for them to answer the call.
Batman has had a few brawler titles to his credit, most were 2D side scrolling action affairs but there has been at least one that was like Streets of Rage 2. Batman is not scared to throw a punch or two and kick his way out of a sticky situation. No wonder Axel and Blaze made the decision to use the bat signal, it may have been just in time.
Superman is also known for throwing punches when needed (he actually uses less weapons in his stories than Batman does). It is not known if the gangs of Streets of Rage 2 are packing Kryptonite or not. They have found a way to damage the man of steel though that is for sure. No wonder Axel tagged in the world’s favorite alien.
There is no word at this time as to whether there are any Batman/Superman villains that make appearances in this version of Streets of Rage 2. That would be awesome if there was, say, Brainiac or the Joker as the main boss. Kind of like they are the ones pulling the strings to get the gangs in an uproar or something.
Streets of Rage 2 is a brawler by Sega for the Sega Genesis 16-Bit console. Since Sega has not released it as freeware I cannot link to anywhere to download it. I can link to ROMHacking.net where you can download the patch file to add Batman and Superman to your copy of Streets of Rage 2 though.
