Xbox’s new Mythic Achievement, a PlayStation Platinum Trophy equivalent, has been revealed through leaked details in the Xbox PC App, with its symbol, unlock sound, and mechanics partially uncovered. The feature, expected later this year, rewards players for completing all base-game achievements but excludes DLC, according to insiders and Xbox Insider tests.
The Xbox Mythic Achievement, a long-rumored counterpart to PlayStation’s Platinum Trophy, has taken shape through leaked details in the Xbox PC App, with its symbol, unlock sound, and mechanics partially uncovered. First spotted by Xbox Insider Stallion83, the feature appears to reward players for completing all base-game achievements—excluding DLC—though its full rollout and retroactive eligibility remain unclear.
The feature was first highlighted by Twitter user Klobrille, who shared a screenshot of the Mythic Achievement’s symbol and a 16-second unlock sound on September 22, 2026. The symbol, described as a little fancier than PlayStation’s equivalent,
and the sound, which includes a “lengthy” audio clip, were revealed in an update to the Xbox PC App. The unlock sound was confirmed by multiple sources, including Xbox Insider Stallion83, who noted the feature’s “far from done” status in the Alpha Skip-Ahead Xbox Insider ring.

How the Mythic Achievement Works
According to insiders and leaked code from the Xbox PC App, the Mythic Achievement is tied to a “BaseGame” group of achievements, excluding DLC. When players complete all achievements in this group, the app unlocks a “Mythic” badge, accompanied by a 16-second sound effect and a custom symbol. The system does not count Gamerscore, meaning players can earn the achievement by finishing original game content without needing to unlock later-added DLC achievements.
A source cited internal code stating, “The Xbox app works out Mythic from a group of achievements that it calls BaseGame. The unlock toast says Unlocked all N achievements in the original game
. The game page has a Required for Mythic achievement
filter, and it labels every achievement outside the group as “Add-on. DLC achievements are not in the BaseGame group, so they do not count. The app counts achievements, not Gamerscore. It is not a
100% Gamerscore” reward.” This design suggests the feature will prioritize core game content over expansions, a distinction that could affect players who complete DLC after the initial release.
Stallion83, an Xbox Achievement hunter with 3,309,665 Gamerscore, shared screenshots of the Completed Mythic Achievement
filter, confirming the feature’s presence in the Xbox Insider program. The filter shows both “Completed” and “Incomplete” statuses, indicating the feature may not apply to all games or could evolve before launch. Stallion83 described the feature as “far from done,” noting that it appeared for them as part of the Alpha Skip-Ahead Xbox Insider ring.

What Remains Uncertain
Several questions about the Mythic Achievement remain unanswered. Microsoft has not confirmed whether it will apply retroactively to older games or how it will interact with backward-compatible titles from the original Xbox, Xbox One, and Xbox 360. Additionally, it is unclear if the feature will be limited to new releases or extended to existing games through updates.
Xbox CEO Asha Sharma hinted at the project in August 2026, stating, Team is working on something for later this year!
in response to a fan’s query. However, the lack of official details has left fans speculating.
Code in the app indicates that it is not a 100% Gamerscore requirement, either. It counts achievements within the BaseGame group, not the associated Gamerscore. The feature’s retroactive application remains uncertain, with one source stating, It remains to be seen whether existing games will support Mythic Achievements, or whether the feature will only be available for upcoming titles.
