How To Add Mutators On Your Unreal Server

Mutators change the rules of every match on your Unreal server, for example giving everyone the same weapon or changing gravity. Unreal doesn't come with mutators of its own, but the community has made plenty.

Adding Mutators

  1. 1
    Download the mutator and unzip it on your computer. You'll usually get a .u file and an .int file.
  2. 2
    Log in to Bropanel and Stop your server.
  3. 3
    In the sidebar, go to Files and upload the .u and .int files to the System folder.
  4. 4
    In the sidebar, go to Settings.
  5. 5
    Under Gameplay, find Mutators and enter the mutator's class name, for example MyMutator.MyMutator. Separate several mutators with commas.
  6. 6
    Click Save & Restart to apply your changes.

The mutator's readme tells you its class name. To turn mutators off, clear the Mutators field and click Save & Restart.
