In Streets Of Rage 3(American Verision) you can play as two secret characters. Shiva who was on S.O.R 2 as Mr.X right-hand man. When you fight him on S.O.R 3 on the first level and defeat him hold the B button+Start button. To get the lovable Roo the Kangaroo just beat up his master on the second level or at the tittle screen hold Uo+B and press Start. In the Japan Verison which is called Bare Knuckle 3 there is a special character that you can unlock. His name is Ash. The reason you won't see him on S.O.R 3 is because HE IS GAY. Not saying that he is a bad character, but he is really gay. To unlock him hold the B button down until the next level.
