Danganronpa: Survivor's Guilt is an in-progress Fangan (a Danganronpa fan game that follows the DR formula with original cast and story) made in RPG Maker MV by Aru & Raven. It is a sequel to Danganronpa: LIVe or Die , but is a standalone game and can be played without any knowledge of the prequel. The game up to chapter 3 (of 6) is available for download.
Two years after the end of the Danganronpa TV show, and one year after the events of Danganronpa: LIVe or Die, a huge meetup event for survivors of the various seasons is held. However, someone releases sleeping gas and kidnaps 16 of the attendees to put them in a new killing game on a deserted island. What they don't initially realize is that all of them won their respective seasons by committing murder and getting away with it - so everyone in this game is already a killer!
