Valve introduced a new Steam achievement system — developers will be able to separate the base game and DLCs

Some achievement hunters have been waiting for such an innovation for many years.

Valve has officially rolled out the new Steam achievement system into full release. Previously, players could access it during client beta testing.

The new system will allow developers to create “achievement sets” — grouping achievements into named categories, tracking player unlock percentages for each of them, as well as adding or archiving achievements over time without taking them away from players who have already earned them.

For example, it will be possible to link a set to DLC ownership so that achievements are only displayed to users who own the DLC. Developers can also group achievements by game modes (single-player/multiplayer), add seasonal sets, or “character sets.”

Sometimes certain achievements are tied to multiplayer or a mode that no longer works. For such cases, there is an option to create “archived achievements.” These achievements will remain visible to players who earned them, and they will retain the ability to feature them on their Steam profile. However, players who did not manage to earn an archived achievement will not see it, and it will not count toward the set's progress.
