Valve Launches Steam Achievement Sets In Beta To Fix Completion Tracking
Valve is treating the completion percentage as a record worth preserving rather than a running tally, which changes what 100 percent means on Steam from a moving target into a snapshot a developer can freeze.
Key Facts
- Valve began offering Steam Achievement Sets in beta on October 16, 2026.
- DLC achievements are excluded from a game's overall completion rate until the player owns the corresponding content.
- The Achievement Archive lets developers hide achievements, including seasonal ones, from players who did not unlock them while keeping them visible on profiles of players who did.
- Seventeen titles support Achievement Sets at launch, including Portal 2, Team Fortress 2, Forza Horizon 5, and PowerWash Simulator 2.
- Steam now lets players compare achievement unlock status with up to three friends, including friends who played a game through Family Sharing.

Valve began offering Steam Achievement Sets in beta on October 16, 2026, on the Steam client beta and for games that have added support. The feature splits a game's achievements into groups, such as single-player and co-op, and adds a separate category for DLC achievements. Base game sets display in blue, DLC sets in purple, and DLC achievements are excluded from a game's overall completion rate until the player owns that content. A companion Achievement Archive lets developers archive achievements, including seasonal ones, so missed time-limited achievements no longer block 100 percent completion. Players who already unlocked an archived achievement keep it visible on their profile, and developers received a rebuilt Steamworks achievement editor with CSV import and export, bulk moving, and developer-only test sets. The beta also adds set-by-set progress bars, a Set Complete trophy, and a comparison tool for up to three friends.
Valve revised the wording across the achievements page at the same time. "All Achievements Unlocked" is now "Completed," and the label applies to games that have been beaten as well as games whose achievement sets are finished. Completed sets can also be added to the Completionist Showcase.
Additional changes touch Family Sharing and store navigation. Games played through Family Sharing appear in the game list, and friends who played through Family Sharing are eligible for the comparison tool. Each game page in the Store and Library now displays whether it has achievement sets.
Seventeen titles already have Achievement Sets in the beta:
- Against the Storm
- Age of Wonders 4
- American Truck Simulator
- Call of Duty: Modern Warfare 4
- Crusader Kings III
- DREDGE
- Euro Truck Simulator 2
- Forza Horizon 5
- Flock Around
- He is Coming
- LEGO Batman: Legacy of the Dark Knight
- Left 4 Dead 2
- Portal 2
- PowerWash Simulator
- PowerWash Simulator 2
- Team Fortress 2
- Victoria 3
Portal 2 splits achievements between single-player and co-op. Team Fortress 2 already has per-class sets and seasonal sets for Halloween and Christmas. Sets can be divided by class or character, with the number and split configured per game. Developers can archive individual achievements or entire sets.
