If the rumors and the statements of a leaker are true, Mafia will soon be available in the Xbox Game Pass subscription.
According to leaker NateDrake on Resetera, Mafia will be released for Xbox Game Pass next month. Neither a date nor an exact game from the series was mentioned.
However, it can be assumed that the Mafia Trilogy includes Mafia: Definitive Edition, Mafia II: Definitive Edition and Mafia III: Definitive Edition.
