Sometimes it seems like a new version of Guilty Gear XX is released every other month, but it's hard to complain when the game play is so good. The newest entry in the series, Guilt Gear Judgment, actually contains two separate games.

Guilty Gear Judgment is a side-scrolling beat-em-up, playing like a much more refined version of a similar mode found in the console version of Guilty Gear Isuka, and also thankfully it does not make use of a button to turn your character around. The controls and game play are a bit different than the Guilty Gear fighters; there are three attack buttons, a jump button, a back attack button, and a button to activate the tension gauge. Like any other arcade-style beat-em-up game, you have several lives in stock, and can collect health, super, and point power ups along the way.

Level progression is generally side scrolling from left to right, and you can move up and down the play field a la Final Fight. Occasionally, there are some areas where you move down staircases, and some areas contain pitfalls that must be jumped over, or bridges that you must remain in the center of, as going over results in a loss of life. The game's playable characters have most of their moves intact, however some of the input motions have been simplifed, and the combos are nowhere near as versatile for a fighting game. As a beat-em-up game, what's in Judgment is quite satisfying, although the enemies, mostly various types of monsters, are a bit repetitive, there are different types of boss fights to help break up the action. In addition to the main story mode, you can also play a survival mode, and play cooperatively with a friend in the network mode.

Judgment's graphics are not as impressive as the Guilty Gear fighting games; the character sprites are smaller and appear a little less detailed on the PSP's small screen, but the number of enemies that can appear on screen with your character at the same time is impressive, and there is no slowdown. The music is standard Guilty Gear fare, being mostly forgettable hard rock and heavy metal tunes. Most of the game's backgrounds are a bit bland, being forest or castle backdrops with little to no animation, but since you will almost always be engaging enemies, you won't have much time to stop and admire them anyway.

Guilty Gear XX Slash is the latest revision to the XX fighting series. It contains two added characters, A.B.A., the giant key-wielding female from Guilty Gear Isuka, and Order Sol, who has some different attacks and abilities to his normal counterpart, and is dressed like rival character Ky Kisuke.

Everything from the console Guilty Gear XX Slash has been retained for the PSP version. Slash features arcade, survival, versus, training, mission (win matches under specific conditions), and M.O.M. (collect medals for points) modes, ensuring plenty of replay value. You can also now choose which stages and BGMs you want to use in versus and training modes.
