Mutators must be uploaded into the "System" folder of your Killing Floor server.

Then to load them you need to create a new command line from the panel / command line changer ; tick the  ?mutator and in the corresponding field type the mutator name to load. To find the mutator name format to use in command line please refer to the mutator installation instructions provided by the mutator creator.

If you cannot find the correct mutator name in documentation you can edit the mutator .ucl file and find the name just after "Mutator = (= ClassName"

For example with mutator antiblocker (mutator name in bold):

Mutator=(ClassName=MutKFAntiBlocker.MutKFAntiBlocker,GroupName=KF-AntiBlocker1.1,IconMaterialName=MutatorArt.nosym,FriendlyName=MutKFAntiBlocker.MutKFAntiBlocker.FriendlyName,Description=MutKFAntiBlocker.MutKFAntiBlocker.Description,FriendlyName=MutKFAntiBlocker.MutKFAntiBlocker.FriendlyName,FallbackName="AntiBlocker 1.1",FallbackDesc="Disables player-to-player blocking during trader time.")

So the name to type in command line is:
MutKFAntiBlocker.MutKFAntiBlocker

If you have multiple mutators separate the names with commas (no spaces):
MutKFAntiBlocker.MutKFAntiBlocker,Mutator2,Mutator3

Then save the newly created command line (after giving it a name containing no spaces nor special characters) and select it to enable.
