Download Myth War Online — osMW client and installer

Playing Myth War Online on osMW takes two downloads: the original MythWar game client, and the osMW installer that points that client at our server. Both are free. Windows only.

Step 1 — Game client

Download and install the Myth War Online game client (build v104835). Install it on any drive other than C: where possible — Windows permissions on the C: drive can stop the client writing its own files.

Step 2 — osMW installer

Download and run the osMW installer. The game client must already be installed, and must not be running while the installer works. The installer applies the osMW files and server connection settings.

Step 3 — Register and log in

Create an account on the registration page, then launch the game and log in with those details. New characters start on the Behemoth world.

Requirements
