Treason is a free-to-play fast-paced social deduction first-person shooter. Inspired by Cluedo/Mafia but with real-time combat, 3-16 players must investigate, shoot, and deceive to survive among Italian mobsters.

In Treason, the Don has been murdered! Innocents must find Clues to identify the Traitors before they strike again.
Each round, a small group of players become Traitors who must eliminate all Innocents. Meanwhile, Innocents work with the Detective and Doctor to expose the killers using the Clue Processing Unit.
