The highest progression level in Overwatch 2 is technically unlimited, as there is no cap on how many levels you can achieve. However, the game’s progression system changes after reaching level 100. Initially, players level up from 1 to 100, earning rewards like hero skins, sprays, and voice lines. Once you reach level 100, you enter a new "prestige" tier, where your level resets to 1, but your border changes to reflect your higher progression tier.
These prestige levels continue to progress indefinitely, allowing players to keep leveling up and showing off their experience with unique borders and other visual indicators. Although there is no maximum level, the focus shifts to showing off your dedication and time spent in the game, rather than hitting a final level cap.
