Valve has started testing a new way to organise achievements on Steam. Achievement Sets, announced on the Steam News blog on October 15, 2026, let developers split a game’s achievements into groups, track progress for each one separately and archive achievements that players can no longer earn. The feature is in beta and only works in games that have added support.
How Achievement Sets work
Players earn achievements as before, by playing. The change is in how Steam presents them. Instead of one long list, the achievements page shows the sets the developer has created, each with its own progress bar. Completing every achievement in a set adds a set complete trophy to the player’s profile, and that status is kept even if the developer later adds more achievements to the set.
Valve describes two kinds of sets:
- Base game sets, available to every player, shown in blue
- DLC sets, which cover paid add-ons, shown in purple, and do not count toward overall progress until the player owns that content
VGC notes that a developer could also use sets to separate single-player and multiplayer achievements, so solo players can complete the part that applies to them.
Archiving seasonal and lost achievements
Developers can now archive individual achievements or whole sets. Players who already unlocked them keep them on their profile, but archived items do not appear for those who missed them and do not count against their completion. Valve suggests this for seasonal events and for achievements tied to online services that have shut down. Its guidance is direct: if an achievement can no longer be unlocked, it should be archived.
The redesigned achievements page also adds global completion rates, filters by set and by locked or unlocked status, and comparisons with up to three friends.
Which games support it
To try it, players need to join the Steam Client Beta, following the instructions on Steam Support. At launch, 17 games support Achievement Sets:
- Against the Storm, Age of Wonders 4, American Truck Simulator and Euro Truck Simulator 2
- Call of Duty: Modern Warfare 4, Forza Horizon 5 and LEGO Batman: Legacy of the Dark Knight
- Crusader Kings III and Victoria 3
- DREDGE, Flock Around, He is Coming, PowerWash Simulator and PowerWash Simulator 2
- Left 4 Dead 2, Portal 2 and Team Fortress 2
Valve has not said when the feature will leave beta.
