Guilty Gear XX Accent Core is a fighting game for the Nintendo Wii, featuring updated graphics and audio components. This version includes a new opening movie, a redesigned menu, and re-recorded voiceovers. Character artwork has been refreshed, and two new tracks were introduced. To enhance game balance, tournament-restricted characters Justice and Kliff were excluded from the roster.
Λ Core also underwent the first major aesthetic change for the series since the original release of Guilty Gear XX. In addition to a new opening movie and a redesigned menu, all voices, including that of the announcer, have been re-recorded (or replaced with previously unused samples), sometimes by different actors. The playable characters artwork was also redone, and two new music tracks, Launch Out and Keep The Flag Flying, were added. Since this revision has been made to balance the game, two characters deemed illegal by tournament standards, Justice and Kliff, were removed from the game's playable roster.
