Streets of Rage 4 doesn't do much to advance the formula of classic beat 'em ups and that's what makes it great. The game can be completed in roughly three hours, which is just enough for this type of game. Unlocking all the Easter eggs is a nice way to add to the nostalgia fix. Playing through with each character offers a slightly different game experience, but the real joy comes from playing these types of games with friends. Streets of Rage 4 is a must play for fans of retro beat 'em ups.
