Shin Megami Tensei: Digital Devil Saga is a duology of role-playing video games developed by Atlus for the PlayStation 2. They are a spin-off of the Megami Tensei series. The first Digital Devil Saga was released in Japan in 2004, North America in 2005, and Europe in 2006. Its direct sequel, Shin Megami Tensei: Digital Devil Saga 2, released in 2005 in Japan and North America, and 2007 in Europe and Australasia. The games were published in Europe and Australasia by Ghostlight and in other regions by Atlus and its North American subsidiary Atlus USA.

Digital Devil Saga follows the Embryon, a tribe who fights against five other tribes in a digital world called the Junkyard. After being infected with a demon virus that grants them demonic powers, the Embryon must fight with and devour the other tribes to ascend to "Nirvana". During the conflict, they shelter a woman named Sera, who has the power to calm their demonic powers. In Digital Devil Saga 2, having escaped into the devastated real world, the Embryon are caught up in the fight against the Karma Society, who are intimately linked to the source of the disaster. The gameplay of both titles feature third-person navigation of playable characters around to-scale environments, and turn-based gameplay against demonic monsters and human enemies.

Digital Devil Saga began development pre-2002 under the working title New Goddess. The game's concept and original draft were written by Japanese author Yu Godai, who collaborated with Atlus scriptwriter Tadashi Satomi until withdrawing from the project for health issues. The gameplay concept of characters transforming into demons was based on an unused idea for Shin Megami Tensei. The second game began development immediately after the first, with the main development effort going into refining and improving the gameplay. While their commercial performances varied, both games were heavily praised by critics for their story, graphics and gameplay. Since release, the game has inspired a mobile prequel, and Godai wrote a series of novels based on her original premise for the story.

Gameplay

In the Shin Megami Tensei: Digital Devil Saga role-playing games, players take control of the characters Serph, Heat, Argilla, Gale and Cielo, with the characters Sera and Roland becoming playable in Digital Devil Saga 2. These characters are able to transform into a demon form, which is their main form in battle. Characters navigate to-scale environments, fighting enemies in both random encounters and story-focused boss battles. After each battle, experience points are awarded to characters. Character abilities are governed by Mantra Grids, a system where Mantras are bought using the in-game currency Macca, then mastering them using Atma Points gained from defeated enemies. The maximum number of abilities that a character can equip at a time is eight. If two or more characters equip a certain ability, they can perform a stronger version of it through a combo. Each character can learn abilities from one of four categories: Physical, Magic, Shield and Auto.

The Digital Devil Saga games use a turn-based battle system, with three allied characters fighting in battle. Both player characters and enemies are governed by a mechanic called the Press Turn system: each character has a symbol representing a turn. The character can pass a half turn to allow the next character an action; turns cannot be passed more than once. If an enemy's weakness is exploited or a character lands a critical hit, an extra turn is gained; if a character resists an attack, a turn is lost. In Digital Devil Saga 2, characters will sometimes enter battle in a half-transformed "berserk" mode, which increases attack power while locking away magic skills and lowering a character's defense. While battle is focused around strengthening characters' demon forms, they can also fight in their human forms using conventional weapons, and can equip ammunition. A human character can perform a combo with one in demon form. The magic system uses nine magic attributes. Ice and Lightning magic have a chance of causing the "freeze" and "stun" status, while Expel magic reduces an enemy's hit points by a certain percentage, and Death magic causes an instant kill. Status magic can inflict status effects on enemies.

Characters gain Karma after a battle is finished, raising their levels. Each time a character's experience level raises, they receive stat boosts. While the protagonist can assign stat points at will, the other main characters each have certain specializations. Money is also dropped, which can be used to buy supplies from merchants. Atma is gained after each battle, but a greater amount is gained from eating enemies. If an enemy is "frightened", the amount of Atma is further increased. Characters can also be afflicted with a status ailment if they overeat. In Digital Devil Saga 2, special Karma Ring items can be assigned to characters to grant stat boosts. Fitting different gems dropped from defeated enemies grant specific stat boosts and effects. Effects range from granting free status buffs on the player party to casting ailments on enemies. Importing save data from the first game enables some skills and abilities learned during the first game to be transferred to the characters that learned them.

Synopsis Setting and characters The first Digital Devil Saga takes place in the Junkyard, a combat simulator program where it always rains. Throughout the story, a conflict takes place between six tribes: the Embryon, Vanguards, Solids, Maribel, Brutes and Wolves and the territories held by them: Muladhara, Svasdhisthana, Anahata, Manipura, Ajna, Vishuddha. The only common ground is a great tower at the Junkyard's center called the Karma Temple in Sahasrara, which acts as a meeting place for all the tribe leaders. The following game is set on Earth, which has been devastated by a phenomenon known as the "Black Sun", a manifestation of God's anger. The survivors of humanity are ruled by the Karma Society.

The main protagonists of the Digital Devil Saga duology are silent protagonist , leader of the Embryon; and , a woman who can commune with God. The other Embryon are the kind ; the hot-tempered the light-hearted ; and the highly logical . The main antagonist is , who is Sera's intersexual biological parent. In Digital Devil Saga 2, two new main characters are introduced: Roland, the alcoholic leader of the Lokapala resistance group; and Madame Margot Cuvier, head of the Karma Society. All the main characters barring Cuvier become infected with the demon virus, a condition that causes them to turn into demonic beings and lust after human flesh.

Plot During a border skirmish between the Embryon and the Vanguards, a demon virus is introduced that infects everyone in the Junkyard: branded with a mark representing their "Atma" and gradually awakening to basic emotions, the people of the Junkyard must devour their foes to satiate their demonic hunger or risk going berserk. Sera, a so-called cyber shaman, arrives suffering from amnesia and is taken in by the Embryon, revealing herself capable of calming their hunger with her singing. The Embryon first become conscious of their new powers when they meet the surviving Vanguards: during their time there, they are forced to kill the Vanguards' leader Harley. Serph is then summoned to the Karma Temple along with the surviving tribe leaders. Once they are assembled there, a female being calling itself Angel orders the tribes to conquer their neighbors and ascend the Temple's tower to "Nirvana", bringing Sera as proof of their achievements. The Embryon decide to ally with the Maribel as a means of defeating the stronger tribes.

After gaining the trust of the Maribel's leader Jinana, they are betrayed by her second-in-command Bat, who allies with the Brutes along with the Solids' leader Mick. Jinana, having refused to eat as she needed to, goes berserk and must be killed. The Solids then capture Sera, leading the Embryon into a fight to the death against Mick. They also successfully trick the Brutes' forces and Bat into a booby-trapped ship, killing them. During this time, the Wolves are subdued by the Brutes, whose leader Varin has awakened memories of a former life where he was known as "Colonel Beck", and unsuccessfully attempted to persuade Angel to release him from the Junkyard. With help from the Wolves' deposed leader Lupa, the Embryon infiltrate the Brutes' castle, but Lupa is killed after going berserk. Later, the Embryon end up fighting Varin, who accuses Sera of being a monster before he dies. Sera regains her memories and runs to the Karma Temple with the Embryon in pursuit. There, Sera faces the human form of Angel, who threatens to delete the Junkyard with a computer virus if Sera does not return to the real world with her. The Embryon arrive and successfully fight Angel, but in the process release the computer virus. The Embryon, Sera and Angel only just escape as the Junkyard is destroyed.

In Digital Devil Saga 2, the Embryon appear in the real world, which is slowly being destroyed by the Black Sun: the only ones able to survive the sun's rays are those infected with the demon virus. Serph, Cielo, Argilla and Gale learn that Sera is the captive of Angel and Madame Cuvier at the Karma Society headquarters. With the help of Roland and a young boy named Fred, the group infiltrate the Karma Society's building. While they attempt to rescue Sera, Angel plans to subvert Cuvier and use the demon virus to create a society ruled by the strong. The Embryon are also faced by Heat, who is working with Cuvier on the promise of Sera's safety. Reaching the EGG, a man-made replica of God, the party rescue Sera, but Heat appears and seems to kill Serph. Both fall into the EGG, and God begins absorbing the Earth's data: in the chaos, Angel kills Cuvier, while the remaining Embryon and Sera, now able to assume a demon form herself, shut down the Power Plant in an unsuccessful attempt to stop the EGG. In the process, both Roland and Argilla are killed by a powerful demon. Returning to the EGG so Sera can speak with God, they are confronted by Heat, who has fused with the EGG and gone berserk. Inside the EGG, Serph is met by a higher being calling itself Schrödinger, who reveals the truth about what happened.

The Karma Society was founded to study God, who was losing faith in humans due to their behavior. Sera was the only survivor of a group of children with the ability to communicate with God. To hide from the pain of the experiments, Sera created an artificial environment populated by benign versions of Karma Society staff: this environment was redesigned to become the Junkyard and the artificial beings would become its five tribes. The original Serph manipulated Sera and his team for his own ends while the original Heat attempted to protect her. When Sera saw Serph killing Heat while linked to the EGG, God felt her pain and attacked Earth. The original Serph was overwhelmed by a flood of data and became a demon before being killed. Now knowing the truth, Serph escapes from the EGG, killing Heat in the process. Sera then decides to head for a secondary Karma facility to communicate with God: on the way, Gale dies while killing Angel, and Cielo sacrifices himself so Sera and Serph can reach the transmission site. As Sera begins transmission, the base is destroyed, killing her and Serph. Their data travels to the sun—the physical manifestation of God—and merges into a new being called Seraph. Aided by the data avatars of the Embryon, Seraph fights God's avatar to prove humanity's worth. Upon victory, Seraph achieves enlightenment and travels with Schrödinger to new worlds, while God restores the sun and Earth. At the game's end, it is shown that the Embryon, Angel, and aspects of Sera and Serph have reincarnated, with a grown Fred acting as their caretaker.
