The game is also playable in the game Sonic's Ultimate Genesis Collection. It is the second game in the Streets of Rage series, a sequel to Streets of Rage and followed by Streets of Rage 3.

Streets of Rage 2 hack created by gsaurus, creates a new "extreme" challenge for the seasoned SOR2 player. Features include: - Heroes are faster and stronger, well balanced and with unique improved moves, including a different infinite combo for each character. - Weapons are now more useful. - Faster enemies and different enemy distribution through the levels. Less opportunities to cheat with enemy activations. There are a couple of interesting modifications such as a "bonus jet" on level 5. - Shorter delay on hits - No delay after punching, so the gameplay is more fluid (SOR3-like) - Improved Skate running (pressing forward twice is more responsive, improved ability to restart running when turning around) - Display number of K.O.s during gameplay - New colours for enemies, players and some backgrounds - BGM 1 and 9 are now used
