Xbox PC App Hints at Possible Mythic Achievement

Published 25 September 2026

Xbox references to a possible new “Mythic” achievement have surfaced in an update to the Xbox PC app, alongside a symbol and an unlock sound lasting about 15 seconds, according to reports describing a clip posted by gaming creator Klobrille. Microsoft has not officially confirmed the feature, its rules or a release date, so it remains unclear whether the app material signals a finalized rollout. Details attributed to TrueAchievements describe Mythic achievements as a zero-Gamerscore reward for earning all of a game’s base achievements. Downloadable content achievements would not be required. If implemented as described, the reward would serve as an additional marker for players who complete a game’s main achievement list, rather than adding to their Gamerscore total. The reports say the app update contained a Mythic-labeled symbol and audio. Klobrille’s post showed the symbol and played the sound, which reports described as roughly 15 seconds long. The material establishes that the references appeared and were demonstrated in a clip, but Microsoft has not verified that they represent a publicly available feature.
