Guilty Gear Isuka marks the first time in the series' history that players will be able to participate in four-person fighting. Whether gamers decide to battle it out two-on-two style or team up for four-player co-op against the computer, it adds an all-new dynamic to the series. The game also lets you customize your character by providing the opportunity to buy new moves and combos and change costumes via a point system. It also introduces three new playable characters for a grand total of 23. Other new improvements include a side-scrolling action game mode, some brand new fighting arenas, and a re-tooled survival mode. The storyline takes a much more prominent role this time around too, with several surprise revelations about new and existing characters.
