Steam launches Achievement Sets to separate DLC trophies from base-game completion
Steam has introduced a beta feature called Achievement Sets that groups achievements into defined collections, distinguishing base-game trophies from DLC-related ones. Base sets appear in blue and DLC sets in purple, with DLC achievements excluded from overall completion tracking until a player owns that content, and a game's 100 percent progress stays locked in even if developers add achievements later. The achievements page has also been redesigned to show set progress and let users compare stats with up to three friends.
