Shin Megami Tensei: Digital Devil Saga 2, known in Japan as Digital Devil Saga: Avatar Tuner 2, is the direct sequel to Digital Devil Saga: Avatar Tuner, both for the PlayStation 2. In addition to an improved mantra grid, the game adds a "Karma Ring" system, allowing the player to increase character stats. By equipping these rings with gem stones found in the game the player can further increase a character's stats.
Digital Devil Saga 2 also adds in the 'berserk form', in which a character can enter a half-demonic state, transforming only a part of their body (typically their arm). They have more powerful abilities, but suffer from weakened defenses.

They find that the land has become uninhabitable due to the sun and the streets are lined with what appear to be human statues.
