Yeah but you have to change some of the .cbf names.
Change "vc2onlindemo.cbf" to "vc2onlindemo.real" and change "vc2onlindemo.cheat" to "vc2onlindemo.cbf".
That way your new cheat file will run in VC2...
At least i think thats right..
IF you have unpacked the data, en changed some data,
()IE INI/weap.txt)
make sure you repack it, and name it vc2onlindemo.cbf.
Just stick it in the vietcong2-online demo folder, and run the vietcong2.exe.
Make sure you keep a backup of your original vc2onlindemo.cbf,
might come in handy.
