Ok guys this isnt something you download, and its actually pretty easy to do.
****NOTICE****
THIS IS ONLY FOR PEOPLE WHO HAVE WINDOWS XP!
I DO NOT HAVE VISTA OR A MAC SO THERFORE I DO NOT KNOW HOW TO DO IT ON THOSE OS'S.
Step 1- go down to the start button, and right click.
Scroll up to where it says "Explore"
A menu of all your computer files will pop up.
Find the Nexon file.
Go into Combat arms => Game.
Near the top left there will be eight values:
CHARS_M_BODY
CHARS_M_FACE
CHARS_M_HEAD
CHARS_SND
CHARS_M_BODY
CHARS_M_FACE
CHARS_M_HAND
CHARS_M_HEAD
Select the last four, and cut them.
Paste into the overall Nexon folder.
Start Combat Arms
Enjoy!
P.S.- After you do this, cut the file from the nexon folder back into the "game" folder to reverse the affects.
P.P.S.- All characters will show up white, including teammates, so this is best used for inside maps, or night maps.
