The latest edition of history's most popular fighting game series features the tuned gameplay and perfect response the series is known for, and throws some novelty into the mix to keep things interesting. Ultra Street Fighter IV features five new characters for you to choose from: Poison, Hugo, Elena, Rolento, and Decapre. Six new battle environments are included: Pitstop 109, Mad Gear Hideout, Cosmic Elevator, Blast Furnace, Half Pipe, and Jurassic Era Research Facility. New gameplay mechanics have been added, such as Ultra Combo Double, Red Focus, and Delayed Standing - plus Street Fighter's gameplay has been rebalanced. Fan feedback was compiled on all of SSFIV: AE's original characters and core system mechanics, and changes were made to create the most balanced, awesome Street Fighter ever.
