Guilty Gear XX Core received a significant overhaul in the form of the ‘Accent Core Plus’ upgrade. The game has been updated with a wide variety of balancing and gameplay adjustments, as well as bug fixes. Along with the return of Kliff Undersn and Justice as playable characters, additional game modes, including Mission and Survival, as well as a brand new Story mode, have been included. The plot continues immediately after the conclusion of Guilty Gear XX, and each of the playable characters has their own distinct storyline to follow throughout the game.
The PlayStation 2 version can be purchased on its own, or as a “append” disc that must be used in conjunction with the game’s initial Core disc. The PlayStation 3 and Xbox 360 releases include support for online play, while the PlayStation Portable version has a 3-on-3 tag match option.
