Shin Megami Tensei: Devil Survivor 2 is a tactical role-playing game developed by Atlus for the Nintendo DS. It is a spin-off of the Megami Tensei series, and a standalone sequel to Shin Megami Tensei: Devil Survivor (2009). It was published by Atlus in Japan in 2011, North America in 2012, and in Europe by Ghostlight in 2013. The story follow a group in Tokyo after a series of natural disasters heralds the arrival of divine forces which threaten to destroy humanity in seven days. Gameplay is similar to the first Devil Survivor, combining grid-based combat with turn-based battle sequences, with a character relationship system unlocking new gameplay elements and different endings.

Devil Survivor 2 was developed over two years by many of the same staff as Devil Survivor, including producer and director Shinjirō Takata, and character designer Suzuhito Yasuda. The team's goal was to expand and refine their work from Devil Survivor. The music was co-composed by Kenji Ito and members of Atlus's sound team, while manga artist Mohiro Kitoh contributed enemy designs. Journalists praised the storyline and refined gameplay, while criticising the high difficulty and lack of new features. The game saw media expansions including a 2013 anime adaptation.

An expanded version subtitled Record Breaker was developed for the Nintendo 3DS and released worldwide in 2015: Atlus published the game in Japan and North America, while NIS America published it in Europe. Record Breaker was produced to both address fan criticism of the 3DS versions of Devil Survivor, and restore cut content. New music was composed by Shoji Meguro, and both Yasuda and Kitoh returned to create new character and enemy designs.

Shin Megami Tensei: Devil Survivor 2 is a tactical role-playing game in which players take on the role of a silent protagonist after a catastrophic event causes turmoil across Japan. Much of the gameplay is carried over from the game's predecessor Shin Megami Tensei: Devil Survivor (2009) and is split into two parts: story sequences which take up half an hour of in-game time, and combat in grid-based field areas. Combat begins when two units meet, transitioning to a first-person turn-based combat where two parties of three get a single round of combat to act: actions include standard attacks, offensive and support skills. Hitting an enemy's weakness rewarding an extra round to the character who landed the attack.

The protagonist and player characters use demons as allies: demons can either be bought at the Demon Auction, or two demons can be used to create a new demon which can be further enhanced using items as part of the fusion. During combat, the party can use Skill Crack to learn abilities from enemies provided the party assigned that skill defeats the marked enemy.

A new feature is the Fate system, in which talking with party members will improve their relationship with the protagonist and raise Fate rank, starting at 0 and capping at 5. Raising the Fate rank allows access to new skill exchange options, combat abilities, and new demon fusion options. Some characters can die permanently in battle, removing them from the story, and the choices made during the story and who the protagonist interacts with leads into one of the multiple endings.

Devil Survivor 2 takes place across multiple cities in contemporary Japan, including Tokyo, Nagoya and Osaka: the premise is that a series of disasters strikes the country, causing devastation and heralding the arrival of supernatural forces which threaten to wipe out the world within seven days. Shortly before the game's events, a website dubbed Nicaea becomes popular, showing the deaths of people close to the user. Nicaea also includes a portal to the Demon Summoning App, allowing someone to control and attack with demons after making a contract.

The silent protagonist is a high school student who ends up caught up in the game's events and gaining access to the Demon Summoning App alongside many others. His three immediate allies are childhood friend Daichi Shijima, classmate Io Nitta, and the airheaded Yuzuru "Joe" Akie. They end up being recruited into JP's, an organization which protects Japan from supernatural threats. Key characters within JP's are its leader Yamato Hotsuin, his second-in-command Makoto Sako, Osaka-based doctor Otome Yanagiya, and lead scientist Fumi Kanno. Other survivors who end up allying with JP's are the dancer Hinako Kujou, young boxer Keita Wakui, former pianist Airi Ban, and chef Jungo Torii. JP's is opposed by a faction led by detective Ronaldo Kuriki, and the protagonist is often accosted by a figure dubbed the Anguished One. The expanded release Record Breaker adds Miyako Hotsuin, a woman who takes Yamato's place as the leader of JP's.
