Valve beta tests Steam Achievement Sets for DLC and multiplayer

Valve has launched Steam Achievement Sets in beta, separating base game achievements from DLC, seasonal updates and multiplayer so a 100% completion badge no longer resets when new content arrives. Developers can also archive broken achievements and earn separate sub-ribbons for full sets.

• Base game and DLC achievements now live in separate sets
• Archived achievements no longer block new players from 100%
• Campaign and multiplayer can be split into different sets
• Feature is in beta, early adopters include Against the Storm and DREDGE
