I know there is a code that makes you invisible to others because I saw someone using it...

So has someone got it? (the one i saw wasn't perfect, i.e. you cant lock on to them or see them, but you can hear them and see the flash of their bullets)

I only want this to mess about with in locked rooms... (i play the EU version, but if you give me the US I can port it :))

Maybe it is a VIP code, but I would prefer if someone actually told me it was rather than ignoring he thread...
