How to test map with mutator in UnrealEd

[ADPdirty]

Years later i too wanted to know

Step#1
Mutator files must be installed into game folder such as C:\UT3\CookedPC\
Step#2
Edit UTEngine.ini that is located in Your User Name\Documents\My Games\Unreal Tournament 3\UTGame\Config
Step#3
Look for InEditorGameURLOptions
Here is an example of RBTT Invasion mutator run in the editor.
InEditorGameURLOptions=?quickstart=1?numplay=1?mut ator=RBTTInvasion.RBTTInvasionMutator

Look up the INI setting for the game options to use for in-editor play (not sure what it'S called) and append ?mutator=MutatorPackage.MutatorClass to it.

You mean UTEngine or UTEditor?

I'm looking through the UTEditor but I don't know where to place the line of code =/
