Black/Matrix

Battles are organized into turns which alternate between the player and the computer. During the player turn any player-controlled character can perform actions in any order, with a maximum of three actions per character per turn. Every character can use the actions "move", "attack", and "item", though depending on the character and the point in the game, they may have others actions as well. The move action allows a character to travel on the map; battlefield maps are composed of square tiles[2] and the number of tiles in a given character's range is determined by their statistics. Characters have a single preset attack technique and can equip any type of weapon appropriate to that technique; for example, a character with the "stab" attack type can equip rapiers, spears, and staffs. Additionally, characters automatically respond by counterattacking, defending, or attempting to dodge when they are attacked; the player can switch the response at any time through the "Waiting Stance" command.[7]

Specific, plot-determined characters have access to the "magic" command at all times, while others require special equipment to unlock it. Spell effectiveness varies from turn to turn, as governed by a "Biorhythm" clock.[7] In place of conventional magic points to manage magic use, Black/Matrix uses a system called "Blood Points". Blood Points can be distributed to individual playable characters before battles to expend in spell casting.[4] Blood points are accrued by attacking the prostrate bodies of defeated enemies, effectively killing them.[4] (Some fallen playable characters are susceptible to the same fate, after which they are lost permanently.)[7] Additionally, the player can infuse a weapon with Blood Points to improve its effectiveness and possibly unlock a special attack[6] called a "latent ability". Latent abilities function like spells in that they cost Blood Points to use and add various effects to the damage dealt by the weapon.

At the conclusion of each battle the game evaluates the player's performance and assigns a letter grade-based rank, which determines the value of bonus items and the amounts of money and experience points the player is awarded. Experience points go into a common pool and the player distributes it to the characters at will, choosing which characters gain experience levels.[6] Upon level-up, the player also determines how a given character's statistics mature, allowing for customization.[4]

Abel (アベル, Aberu) (Hiroshi Kamiya), is the amnesiac silent protagonist of Black/Matrix - his dialog is not shown on screen. A white-wing slave, he is locked in Golgoda Prison for the crime of love. He exhibits a power to transform black-wings into white-wings, which marks him as the 'messiah'.

Black/Matrix begins with the player choosing a black-wing 'master', i.e. companion, for Abel,[6] which affects the beginning and ending of the game. The choices are:

• Domina (ドミナ, Domina) (Noriko Hidaka), the 'pure' girl.
• Purica (プリカ, Purika) (Mika Kanai), the 'childish' girl.
• Michette (ミシェット, Mishetto) (Yuko Miyamura), the 'lolita' girl.
• Kurreshes (クレージュ, Kurēju) (Junko Shimakata), the 'tomboy' girl.
• Prague (プラハ, Puraha) (Wakana Yamazaki), the 'mature' girl.

There is an additional secret male master, Zero (ゼロ, Zero) (Kentarou Itou), who becomes available after inputting a code (which differs in each release).[7]

Leburobus (レブロブス, Reburobusu) (Hideyuki Hori) is a white-wing criminal. He was once a gladiator, but was sent to Golgoda Prison for killing his former masters. He is very tough and uses swords and other heavy weapons. He seeks "freedom", and joins Abel's escape.

Gaius (ガイウス, Gaiusu) (Kaneto Shiozawa) is a white-wing criminal. He gained fame as "Gaius the Gale" for stealing from the rich to give to the poor, but is later imprisoned for the crime of "hypocrisy" as a result. He joins Abel's escape.

Phillipo (ピリポ, Piripo) (Hiro Yuuki) is a blond-haired boy whom Abel encounters in Golgoda Prison at the beginning of the game. Though he is a black-wing, he is shunned because of his weakness. He escapes with the party and becomes an archer.

Johannes (John) (ヨハネ, Yohane) (Takeshi Aono) is the black-wing former high priest of the Temple of the Sun who lost his position after a power-struggle. He is a necromancer who can use magic to revive dead characters as zombie decoys. After witnessing Abel's mysterious powers, he joins the group.

RupiRupi (ルピルピ, Rupirupi) (Kikuko Inoue) is a black-wing former student of Johannes who took over his research, eventually becoming a Demon Knight.[7] She casts powerful healing spells. Her hobby is writing in a "revenge diary".

Marco (マルコ, Maruko) (Ai Orikasa), a white-wing, is known as the "Miracle Boy" for becoming the first person to don an Arch-demon Armor. Despite his youthful looks, he is the leader of a white-wing liberation movement.

On release, Famitsu magazine scored the Dreamcast version of the game a 30 out of 40.[8]

Black/Matrix II brings the series into full 3D,[11] modifying gameplay elements found in previous Black/Matrix releases. The game is divided into four chapters, and the basic flow of gameplay initiates with the player selecting a destination on the overworld map, followed by alternating expository cut scenes and battle maps. Towns, a usual element of tactical RPGs that allow for the purchase of items and equipment, are omitted in Black/Matrix II and shops are accessible from the overworld map and pre-battle menus.

Black/Matrix II features a branching plotline, where the player's choices influence the course of events.[12] There are numerous possible endings and four possible heroines.

Reiji (レイジ, Reiji), the main character, is said to be the strongest devil in Hell. Widely known by the sobriquet "General Tempest", he is the younger brother of the master of Hell, and the leader of the "Fear Quartet" of top-ranking devils. Despite his power, Reiji is killed when human armies invade Hell and resurrects later with no memory of his prior life.

Vidia (ヴィディア, Vidia) is Reiji's subordinate and friend. Known as the "Killing Dust", she favors broadswords and other heavy weapons and is teased for her fierceness and impatience. She harbors an unrequited love for Reiji.

Gilvise (ギルヴァイス, Giruvaisu), like Vidia, is Reiji's subordinate and friend. He has a glib manner of speech and appears to not take things very seriously, but is actually very observant and cool-headed. He serves as Reiji's main adviser.

Ridiearl (リディエール, Ridiēru) is the commander of the paladin army that led the human invasion of Hell. She has a zealous hatred of devils, yet bears a striking physical resemblance to Jenarose, the master of Hell.

Parge (パージュ, Pāji) is the only female member of the Fear Quartet. She possesses a power called Squeeze that drains the life from anyone who approaches her, inspiring a lifelong sense of isolation. When her deadly powers fade after the death of the master of Hell, she begins looking after an abandoned human child.

Uni (ユーニ, Yūni) is a member of the Fear Quartet whose bishōnen looks disguise ruthless battle capabilities for which he is feared by foes and allies alike. As he enjoys pulling the wings off of his defeated opponents, he is nicknamed "Feathercide Uni".

Forester (フォレスター, Foresutā) is a member of the Fear Quartet known throughout Hell for his intelligence. Like a mad scientist, he has no interest in anything other than his experiments and the automata he builds.

On release, Famitsu magazine scored the game a 30 out of 40.[13]
