All eight original "World Warrior" characters are now in IV, along with half of Street Fighter II's boss camp, Balrog and Sagat. Those ten classic fighters are joined by the aforementioned Crimson Viper, French mixed martial-artist Abel, and luchador El Fuerte. The game plays purely 2D; parries, alpha counters, air-blocking, custom combos, and other such potentially cumbersome elements are being thrown out, forcing the game back to a state more closely resembling down-and-dirty Street Fighter.
