Rockstar is going to repeat the pattern in the generation recently started, that’s adapt former titles to the new systems to kept the base for the online modes. Red Dead Redemption could receive the same treatment.
Amazon listed (now deleted) a title called Red Dead Redemption: The Outlaws Collection. This pack would include Red Dead Redemption Remastered and an enhanced version of Red Dead Redemption 2 for Xbox Series X | S and PS5. The release date was a placeholder estimated for December 2021.
