About Impostor Online
Impostor Online is a multiplayer murder mystery and social deduction game for 4–16 players, inspired by Werewolf and Town of Salem. Each match assigns you a secret role. Killers target players at night while others investigate, heal or scheme; in the morning, everyone argues, accuses, lies and votes to execute a suspect. Play continues until one faction wins.
Factions
Three factions compete for victory:
- Civilians: find and eliminate every killer before it is too late.
- Impostors: eliminate Civilians until they outnumber them, with no other killers remaining.
- Neutrals: pursue their own win conditions.
Roles
Each role has its own abilities and objectives:
- The Impostors: recognize one another at night, coordinate in secret and choose one player to eliminate. They win when they outnumber the Civilians and no other killers remain.
- The Investigator: investigate one player each night to discover their exact role. Revealing the truth too soon can make you the killers’ next target.
- The Nurse: heal one player each night, but cannot heal the same player two nights in a row.
- The Hunter: take one final shot for revenge if murdered at night or lynched during the day.
- The Killer: act alone, murder one player each night and win by becoming the last person alive.
- The Jester: try to get lynched. Afterward, the Jester unleashes a live bomb that players can pass between one another before it explodes.
