UE2 - UT2kX Changing xplayer for custom player(controller)

Hi, I was wandering if you guys know how to change the xplayer that is used in the game for a custom player controller. To clear out what I'm asking I'll tell you what I'm trying to do:
I saw in this forum that to remove the adrenaline combos you would have to change some functions in the xplayer class. And so I did, but I don't know how can I tell the game to change the custom one for mine, I have an idea that this is done in the mutator class, but i dont know in what function neither how =/
Oh, and , another thing: I don't know if this will change anything, but I already use a custom pawn, and change it in the mutator class. so if I change the controller class, will this imply in some necessary changes in the pawn change too?

tanks!!

OBS: is good to be back here, since the forum had a problem I'd lost my ID and didn't had time to create again, and now that I'm doing a different project I decided to change it to a new ID (Old ID: NarutoSensou) =]

No, because I will use the adrenaline =/ for what i've seen the only way is to reaplace playercontroller, and since I don't expect to use bots(only custom paws, that don't have adrenaline) this won't be such an advantage =]
And what problems would I have replacing the player controller? Could you tell too the most er... problematics?

I was wandering if is possible to create some variable similar to adrenaline in a custom pawn class, since it's seams troublesome to create a custom controller class...
