So my question being, if I were to unlock the weapons and body types would I be able to play with my mate without getting banned or something?
I don't think this game uses VAC but still...
If I use it in a single player scenario, then use the same character I have unlocked everything with on multiplayer with my friend will I get flagged as a cheater and get my cd key disabled or something?
Logically that sounds about right. Personally I wouldn't risk using a character you've unlocked everything with with a trainer in MP.
Also @ Escthiil- Afghanistan was probably just the default country since it comes first alphabetically. You can change your profile country here: Link
