Guilty Gear: Judgment is a side-crolling, beat em' up spin-off of the Guilty Gear series, exclusive to the PlayStation Portable, being overall the fifteenth installment.
The gameplay in Judgment is similar to the GG Boost Mode found in Guilty Gear Isuka. Instead of one-on-one 2D fighting, Judgment is a side scrolling beat em' up game. Core gameplay consists of defeating large amounts of enemies and bosses across eighteen levels, while completing each character's story, which are presented in short conversations between chapters.
Instead of the series' essential Punch, Kick, Slash and Heavy Slash buttons, there are Light, Medium, Heavy Attack and Jump buttons, respectively. There is also a Back Attack and a Psych Burst Recovery that covers a large range and recovers health if enemies are hit. The Tension Gauge is again used for Overdrive attacks, while the Burst Gauge, when filled, allows unlimited Overdrive attacks until it depletes, or the use of the aforementioned Psych Burst attack. Enemies drop health or tension boosts, extra lives or point items. Move lists are slimmed-down and re-adjusted in order to coincide with the new beat em' up gameplay.
The game presents three modes, besides Options Mode. In Story Mode, the player assumes the role of a character who encounters others at intervals during the game, and unlocks those they encounter. The game's ending character specific, but is usually shared with another related character. Besides this, he game also features a co-op 2P Player Mode, and a Survival Mode, where the player has to survive increasingly more difficult areas until they are defeated.
Judgment is set in small kingdom known as Villtania in eastern Europe, Isene. A powerful and villainous sorcerer named Raymond has been performing experiments on villagers, leading to their transformation into monsters. He believes his work to be revolutionary, and wishes to become a god. As there has been no communication from Villtania for a week, the United Nations declares an international emergency and offers a large reward for any warrior brave enough to restore order, and the character the player selects assumes this role.
The player makes their way through Villtania, defeating the transformed villagers and interacting with their respective rival or related characters. The player confronts Raymond at various intervals. During one confrontation, he summons Inus, the Dark King of the Underworld, to kill the player, but this plan backfires as Inus consumes him. Inus is defeated by the player; however, Raymond absorbs Inus' power, thus becoming Judgment. It was Raymond's plan to be consumed by Inus so that he could do so. Eventually, Judgment is also defeated by the player, and Inus, wishing to stay dead, consumes Judgment in his weakened state and banishes him to the Underworld.
