Λ Core is the third revision of the original Guilty Gear X2 fighting game. This edition includes balance changes and a new special move: Force Break. The characters either have new special moves or existing ones upgraded, or turned into a Force Break, which consumes 25% of the tension bar. Other gameplay changes include new moves that throw and hold an opponent against floors or walls, throw breaks, and Slashback a parrying move with reduced block stun. Two characters have been removed: Justice and Kliff. Unlike the earlier revisions, the graphics and sounds have also been updated. Many of the voices have been re-recorded or replaced, the players' artwork was redone and there are 2 new music tracks. There are 3 fighting systems per character: Guilty Gear, Guilty Gear X, and Λ Core.
