Tip

For a custom mutator, upload its files as its readme describes: .u and .upk packages go anywhere under UTGame/CookedPC (for example CustomMaps), .ini files in UTGame/Config and .int files in UTGame/Localization/INT. Then enter its class name in Mutators, for example MyMutator.UTMutator_MyMutator. The mutator's readme tells you the class name.
