Overview
- Valve rolled out the new Achievement Sets feature into the Steam client beta in mid‑October 2026, letting users test the changes and send feedback to the company.
- Developers can group achievements into named sets that each show their own progress bar and award a visible “set complete” trophy when finished.
- Studios can archive individual achievements or whole sets for time‑limited events so players who missed them won’t see them on profiles or have their completion blocked.
- The refreshed achievements page summarizes overall progress, shows per‑set breakdowns, and adds the ability to compare achievement progress with up to three friends.
- Valve published a launch list of supported titles including Portal 2, Team Fortress 2, Left 4 Dead 2, Forza Horizon 5 and several Paradox games, and wider impact depends on how many developers opt in and categorize their achievements.
