Valve is rolling out a new feature for Steam called achievement sets, which allows developers to organize base game and DLC achievements into distinct groups. According to Valve, players unlock achievements through standard gameplay, but the platform now displays these unlocks within the specific sets created by developers. This structure breaks long achievement lists into smaller categories, making it easier for users to review completed items and identify related achievements to pursue next. Each set includes its own progress bar, and completing all achievements in a set awards a visible "set complete" trophy. The feature is currently available on Steam.
