Ultra Combo Double, Street Fighter Wiki

The Ultra Combo Double (ウルトラコンボダブル, Urutora Konbo Daburu?) is a new mechanic introduced in Ultra Street Fighter IV. The Ultra Combo Double feature allows players to select both their character's Ultra Combos at the same time - as opposed to choosing between the two. The option can be found on the Ultra Combo Select screen, underneath the character's two Ultra Combos and indicated by a red "W". For most of the cast, Ultra Combo Double reduces the damage output of each Ultra Combo to 75%. However
