What is Impostor Online?

This free-to-play, Early Access social deduction game divides 4–16 online players into civilians, impostors, and neutrals in a town threatened by killers. You use role-specific abilities at night to investigate, heal, or kill, then discuss suspicions and vote to execute a suspect during the day. Each faction pursues its own victory conditions.
