Guilty Gear X ver 1.5 is the eighth entry in the Guilty Gear series, and a updated version of Guilty Gear X running on the Sammy's Atomiswave arcade system. Announced in February 2003 at the Amusement Expo, its main changes were in the field of character balance, adding moves to make it more similar to the recently-released Guilty Gear XX. Unlike the previous Guilty Gear X Plus update, Ver. 1.5 does not include an enhanced Story Mode nor Justice or Kliff Undersn as playable characters.
