Xbox Unveils 'Mythic' Achievements: Retroactive 100% Completion Reward for Insiders

Key points

• Xbox officially announced Mythic Achievements on September 29, 2026, beginning the rollout to Xbox Insiders.
• The feature is retroactive, meaning players who previously completed all base achievements in eligible games, including Xbox 360 titles, have already been awarded the status.
• Mythic Achievements are unlocked by completing all original base-list achievements; DLC and title update achievements are not required and are tagged as 'add-on.'
• The update introduces a new progress bar on game achievement lists and a new gaming tab on Xbox profiles to track Gamerscore milestones and Mythic status.
• Mythic Achievements carry zero Gamerscore and feature a unique 'heroic frame' in achievement history, with no notification spam for retroactive unlocks.

Background

Xbox CEO Asha Sharma previously confirmed that a Platinum trophy equivalent would arrive later in 2026. In late September, leaks revealed a 15-second unlock animation and sound effects for the feature. This launch follows recent Xbox Insider updates, including the expansion of the disc-to-digital feature to all Insider rings in early September.

How outlets are covering it

TrueAchievements emphasizes the retroactive nature of the feature and the lack of notification spam, noting that profiles will simply display the count of previously unlocked Mythics. The Verge highlights the direct comparison to PlayStation's Platinum Trophies and notes that the feature was leaked in an Xbox PC app just one week prior. UA.NEWS and ixbt.games focus on the technical implementation, such as the new progress bars and the exclusion of DLC achievements from the Mythic requirement. All sources agree that the feature is currently limited to Xbox Insiders, though specific Insider tiers (Alpha Skip-Ahead or Alpha) have not been officially specified by Xbox.

Why it matters

This feature addresses a long-standing request from the Xbox community for a completion reward equivalent to PlayStation's Platinum Trophies. By making the feature retroactive, Xbox acknowledges the achievements of long-time players without requiring them to replay games. The exclusion of DLC and post-launch updates from the Mythic requirement ensures that the status remains attainable for games that have received significant post-launch content, preventing the feature from becoming obsolete or unattainable for older titles.

What to watch

Xbox has not announced a timeline for the general public rollout beyond the current Insider testing phase. The company has not specified which Insider rings are receiving the update, though it is expected to be both Alpha Skip-Ahead and Alpha. Future updates may include broader integration of Mythic Achievements into Xbox Guide and achievement details to help players track progress across platforms.
