Dev Builds


Metamod:Source uses rolling releases, and updates are continuous. Updates to stable versions of MM:S are small and non-disruptive. It is generally recommended to run the latest stable build, however, it is not necessarily urgent to upgrade when a newer build appears.

These are unstable, development MM:S builds. For stable builds, see this page instead.
