DPAD UP = God Mode
DPAD RIGHT = Noclip
DPAD LEFT = x2 Speed
DPAD DOWN = Normal Speed
There's probably quite a bit more you can do with this but I'm not gonna bother.
HOW TO INSTALL
Go To GAMES/BLXXXXXX-Call-of-Duty-3 (or whatever yours is called)/PS3_GAME/USRDIR/config
Now the files you'll be focusing on are the mp_ps3_x.cfg files.*
mp_ps3_a = Controller 1
mp_ps3_b = Controller 2
You want to backup the one your using (probably Controller 1)
Download the modded cfg (You must login or register to view this content.)
Rename the file to the CFG your using (In my case, mp_ps3_a.cfg)
Replace the file in your config folder via MultiMan or FileZilla*
Load into MP
TAH DAH, ENJOY!
