IMPORTANT: Client Notice

Recommended Client Version

To ensure maximum compatibility with map scripts and exploit the latest network fixes, we strongly recommend using the 2011M client version. This version is the most stable for running downloaded map scripts successfully.

  • 2011M offers the best balance for running custom scripts and recent maps.
  • Using other clients may result in scripts not loading correctly.
  • Always check the client-specific compatibility notes before launching.
