What happened

Valve has launched a new Steam feature called 'achievement sets' that allows developers to organize achievements from a base game and its DLC into distinct groups, each with its own progress bar. Players unlock achievements through normal gameplay but see them organized into developer-created sets when browsing. Completing an entire set awards a 'set complete' trophy visible on the player's profile. The feature supports seasonal achievement sets that developers can archive, enabling time-limited holiday or season-based achievements. A range of games already support the feature, including Against the Storm, Forza Horizon 5, Portal 2, and Team Fortress 2, with the new functionality available in the latest Steam client beta.

Context

This addresses the existing problem of games with extensive DLC or seasonal content accumulating long, difficult-to-navigate achievement lists. By segmenting achievements and providing visual progress indicators, the feature reduces friction for players trying to understand what they've completed and what remains available. For developers of ongoing games with rotating seasonal content, the ability to create temporary achievement sets creates new design opportunities tied to time-limited events.
