Steam Beta Client adds Achievement Sets
The 15 October update groups base-game and DLC achievements, with archiving and completion preservation.
On 15 October 2026, Valve released a Steam Preview/Beta client update introducing Steam Achievement Sets to organise, track and complete achievements. Base-game and DLC achievements can be grouped separately, making overall progress easier to see.
Seasonal or unobtainable sets can be archived. Completed sets remain completed when new sets are added. The achievement page also gains a clearer display and progress summary.
A producer’s perspective
Developers might need achievement metadata updates, increasing integration and testing work; non-backward-compatible APIs could produce synchronisation bugs. Assessing impact requires knowing how many released games need changes and Valve’s expected average update time.
