-if u go to ur combat arms folder
-then u go to the game folder
-u will see a file named CHARS_M_BODY.rez
-move that file to the BGM folder above
And when u start ur game everyone will be invisible but u and u will be half way in the ground with this it makes glitching much easier but u wall off the map and die a lot.
this hack is most useful for the Quarantine map because u can hide under the boxes by the jailcell.
i didn't make figure this out I'm just opening it up to more people.
i may upload a youtube vid of this tomorrow.
