Valve introduces Achievement Sets splitting single-player and multiplayer on Steam

Valve released the Steam Client Beta update on October 15, 2026, at 6:03 PM EDT, introducing Achievement Sets that split achievements into categories such as single-player and multiplayer.

Valve says each Achievement Set includes its own progress bar, and completing all achievements in a set awards a “set complete” trophy on the user profile. Developers can split achievements into categories like single-player, multiplayer, DLC, updates and events. Users can see a customized total when they compare Achievement Set progress with as many as three friends, counting only the DLC and achievements they have.

Developers can archive achievements or whole sets that are no longer obtainable; archived items stay visible on profiles of earners but do not appear for others and do not block set progress. On the updated achievement page, you can compare your progress with three friends, pin achievements you’re aiming for, and filter the list more broadly.

Two set types exist: Base Game sets, shown with a blue progress bar, are earnable by all players, and DLC sets, shown with a purple progress bar, remain excluded from progress until you own the content. This distinction clarifies what counts toward a player’s completion. Valve highlights that finishing every set adds extra satisfaction and gives developers freedom to design their own achievement groups, such as a set based on eight character classes.

Achievement Set progress is tracked per set; completed sets are preserved even if new achievements are later added to the same set. Players therefore keep their set‑complete status despite future updates. To try the new Achievement Sets, players need to go to Settings, choose Interface, then select Client Beta Participation.

The updated achievement page lets players compare progress with up to three friends, pin pursued achievements and use expanded search filters. Valve made the beta available on October 15, 2026, launching it at 6:03 PM EDT.

Completed sets now appear in the Recently Played section, Games List and Library; the former Perfect Games tab is renamed Completed and supports the Completionist Showcase. Linux users now get a 64‑bit Steam client that runs within a Steam Runtime container.

Games played via Steam Family Sharing appear in the Games List and enable friends with shared playtime to join achievement comparisons. Sharing a library broadens the circle of people who can view progress. Two kinds of sets exist: Base Game sets, which everyone can earn and show a blue bar, and DLC sets, shown in purple, that only count toward progress if you own the extra content.

Store and library pages now show when a title has Achievement Sets enabled. The system measures progress separately for each set, so finishing a set stays complete even if the game later adds more achievements to that set.

Valve says completing all Achievement Sets brings extra joy and allows developers to create custom sets, exemplified by an eight class‑based set suggestion. Finished sets now show up in Recently Played, your Games List and Library, and the old Perfect Games tab has become the Completed tab, which highlights your Completionist Showcase.

Valve notes that ongoing DLC, expansions and seasons can make new achievements hard to find and may unintentionally break completion status for players who already finished a game. When you share a library through Family Sharing, those games appear in your Games List and let friends who’ve played them join your achievement comparisons.

Users can opt into the Steam client beta via Settings > Interface > Client Beta Participation to test the new Achievement Sets. The store and your library now flag games that support Achievement Sets, so you can see this before buying or launching.

The beta moves the Linux Steam client to a 64‑bit application running inside a Steam Runtime container. It also adds Remote Play Display Style settings for aspect‑ratio adjustments, a Steam Controller firmware fix, and improves Library activity feed offline support. The beta also brings Remote Play display tweaks for aspect ratio, fixes the Steam Controller firmware, and upgrades offline support for the Library activity feed.

Among the titles that now include Achievement Sets are 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, Portal 2, PowerWash Simulator, PowerWash Simulator 2, Team Fortress 2 and Victoria 3. Valve warns that frequent DLC, expansions and seasonal updates can hide new achievements and might accidentally reset completion for players who thought they’d finished the game.

Valve will continue refining Achievement Sets during the beta period and directs feedback to the Steam Client Beta discussion group. Valve plans to keep improving Achievement Sets while the beta runs and wants players to share thoughts in the Steam Client Beta discussion group.
