the engine is not a keylogger.. and if it was, it wont make nexon know that you moved/deleted some texture files =S
BTW...do anyone know what files do I have to move/delete in order to make "white walls" but without falling trough the freakin floor? XD
Have you looked @ engine.exe with ollydbg? If you know what your doing (which you probably don't) then look at it, there are some fucked up codes about where it draws information from, not relating to Combat Arms.
Try quoting my whole post pl0x, you know your precious .dmp file in the Combat Arms folder? It contains many much information on what is gathered from your computer, including a file-check @ the startup of each game. From there it logs your IP and user that you log in with.
