Steam has rolled out Achievement Sets and a redesigned achievements page to all users. The feature lets developers group a game’s achievements into separate collections, such as a base-game set and additional sets for downloadable content. Players can track completion for each group independently, while newly added content no longer has to erase a previous set’s completed status.
The update makes Steam’s achievement system more flexible, especially for games that continue to receive expansions, seasons or other updates long after release. It does not automatically reorganize every game on the platform, though. Developers must support Achievement Sets for their titles before players will see the feature applied to those games.
Achievements can now be split into sets

Achievement Sets let developers organize related achievements into named groups. A game might separate its base campaign from multiplayer challenges, or use different sets for expansions and other large additions. Each set has its own progress bar, so players can see how much they have completed without treating every achievement added over the game’s lifetime as one growing checklist.
When a player completes every achievement in a set, Steam records that completion with a set trophy. If a developer later adds more achievements, the player’s earlier completion remains intact. That gives studios room to keep expanding a game without making long-time players feel that a previously completed game has suddenly become incomplete.
DLC achievements have their own progress

The system can place achievements tied to paid DLC into separate sets. Players who do not own the additional content will not have those achievements counted toward their overall game progress. Once they own the DLC, its achievements appear as their own track, helping distinguish the base game’s completion from optional expansions.
That separation is useful for games with years of add-on content. Under a single undivided list, a new expansion can make a previously complete game look unfinished, even for someone who has no intention of buying the DLC. Sets let players see the content they have completed while making new achievements visible to those who can actually access them.
The new page adds more ways to track progress

Steam’s redesigned achievements page brings overall progress, individual set progress and achievement details together. Players can toggle global completion statistics, search achievements and filter by set or by whether they are locked or unlocked. The update also adds tools for comparing progress with up to three friends, including completed sets and DLC progress.
Completed sets now appear in more places across Steam, including the Library, Games List and profile. The old “Perfect Games” tab has been renamed “Completed” and now includes games with completed achievement sets as well as games where every achievement is complete. It gives players more ways to show progress without requiring every game to reach one all-encompassing 100 percent mark.
Seasonal content can be archived

Developers can archive an achievement or an entire set when it is no longer possible to unlock. That could apply to time-limited seasonal events or achievements tied to content that has ended. Players who already earned the achievement will continue to see it on their profiles, while players who missed it will not have it block completion of the set.
This addresses a familiar frustration with online games that retire seasonal challenges or event modes. An achievement list can remain visible without permanently preventing future players from completing the game. The feature gives studios a way to preserve a record of past content while keeping completion attainable for people who arrive later.
Game support still depends on developers
The update is available across Steam, but Achievement Sets appear only in games whose developers have implemented them. Steam introduced the feature in beta before the general rollout, and developers have been adding support to individual titles. Players may therefore see the new interface on Steam before they see sets in every game in their library.
That distinction is important: the rollout changes what Steam can display and what developers can configure, rather than automatically rewriting every achievement list. As more studios adopt the system, players should see clearer separation between base games, DLC and seasonal content. The biggest immediate benefit is that a new expansion no longer has to undo a player’s completed set.
