Control Resonant Plans Repeatable New Game+ Runs for October
Remedy is preparing NG++ so players can keep restarting without deleting their progress. Photo Mode is expected in November.
Control Resonant’s current New Game+ lets you finish the story one more time. Remedy is preparing NG++ to let you keep starting additional NG+ runs without erasing your progress, with October as the target month.
October: repeated New Game+ runs
Remedy’s September 25 update says NG++ should arrive in October. The change removes the current limit of one additional completion; the announcement does not detail difficulty scaling or which individual items carry into later runs.
You can already keep playing after the main story to finish side quests, find ones you missed and discover World Feats. Those activities do not depend on the NG++ update.

November: Photo Mode
Photo Mode is expected sometime in November. Remedy says it consulted community virtual photographers while developing the feature, but prioritized getting the game ready over including it at launch.
Neither update has an exact release date yet. Treat October and November as Remedy’s current targets when deciding whether to start another run or wait for Photo Mode.
