An Xbox PC app update appears to have exposed the name, emblem and unlock sound for a new completion reward called a Mythic Achievement. The assets suggest Microsoft is moving closer to giving players a distinct marker for earning every achievement in a game, but Xbox has not formally announced the feature's rules or release date.
Klobrille posted on September 22 that the update revealed the Mythic Achievement label, a symbol and an unlock sound. The post described the reward as an expected marker for reaching 100% Gamerscore in a game. That is a report about assets found in the app, not confirmation of the final implementation.
Insider Gaming reports that the audio cue runs for 16 seconds. Its accompanying image shows a green circular badge with a pale, star-like center beneath the words “Xbox Mythic Achievement.” Neither source shows the feature working on a retail Xbox account or identifies a public rollout date.
A completion reward is taking shape
The apparent design resembles PlayStation's Platinum Trophy, which marks completion of the rest of a game's trophy list. For Xbox, the expected trigger is 100% of a title's Gamerscore. The comparison explains the feature's purpose, but it does not establish that Microsoft's eligibility rules will copy Sony's system exactly.
The new assets follow an earlier clue. that high-Gamerscore player Raymond “Stallion83” Cox saw a Mythic Achievement category on September 19. The outlet stressed at the time that Xbox had made no official announcement.
