Or just grab the attached configuration file (angelmapperhalloween.ini) and add it to your UT2004/System folder.
You'll see this when you open the ini with notepad or another text editor:
[HMDEK2011.HalloweenMutator]
bSkeletons=False
MaskName=BloodyKnife
;MaskName=HockeyMask
;MaskName=PumpkinHead
;MaskName=Skull
;MaskName=FrankBunny
;MaskName=Mandalorian
;MaskName=Boba
;MaskName=Happy
;MaskName=Trollface
;MaskName=ShroomHat
;MaskName=StarMan
;MaskName=Halo
;MaskName=Horns
;MaskName=BloodyKnife
;MaskName=Unicorn
The different mask options are "commented out" with semicolons. The one at the top of the list doesn't have a semicolon in front; this is the "chosen" mask. Just change which one doesn't have a semicolon in front to change to a different mask when you play on the server.
You can also set up your mask in instant action mode (pick the mutator, and pick your mask in the mutator configuration tab.)
