The Vampire wins by secretly turning all the living players into undead. The Vampire demonizes players; if a demonized player is killed in the night, they will instead turn into an undead.

Each night, the Vampire may demonize one player. On even numbered nights, the Vampire may demonize a second player. The player will not know they have been demonised. Vampires cannot demonize themselves or other members of the underworld. When a demonized player is killed in the night, they will turn into an undead. The Vampire wins the game, along with the undead, if all players are either Vampire, dead or undead. Demonizing a player is an immediate ability. If there are several Vampires, they work together. If no members of the underworld channel remain, all demonized players are no longer demonized.

The Undead is a part of the vampire’s secret army and pretends to be their old role. If a demonized player is killed during the night, they will not die, and will instead lose their original role and become an Undead.

The Undead wins together with the vampire. A player converted into an Undead loses their previous role. However, if they were a member of a group channel, they will remain as such and will still be able to vote if applicable (though their vote will not count). If all members of a group have changed role or died, the group is disbanded and any abilities it may have had are lost.
