What it does

The addon sorts its roles into four factions. The Civilian faction holds more than 40 characters, including Doctor, Detective, Athlete, Superstar and Psychologist, and its players win by finishing tasks that assist the Vigilante. The Killer faction holds more than 25 characters, such as Ninja, Enforcer, Demolitionist, Morphling and Puppeteer, and aims to eliminate every non-killer player.

The Neutral faction has more than 30 characters, including Gambler, Thief, Ghoul, Nian and Monokuma, each with its own personal victory condition. The Vigilante/Sheriff faction has more than 10 characters, among them Patroller, Advanced Vigilante and Baseballer, and its Possess ability lets a player eliminate killers. Original signature characters, physique types, economic types and special types such as Split personality and two players sharing one body add further variety.
