New Game+ is a replay mode that lets a player begin a game again after finishing it while retaining selected progress, equipment, abilities, or other advantages. The exact carryover rules vary by game; enemies, difficulty, or available challenges may also change.
In games, this mode encourages replay by letting players revisit familiar content with a different level of power or new constraints. Clear rules help players understand what carries over and how a run is balanced, especially when replay features connect to competitive leaderboards. New Game+ is a game-design term, not a cybersecurity mechanism, but it illustrates how software features can change progression and user experience.
