(adsbygoogle = window.adsbygoogle || []).push({}); Someone else posted a thread asking about hidden challenges, and I realized no one else has spoken of these (from what I could tell) on nextgen. So here's a thread listing as many HIDDEN challenges as I found myself, or read about. Please keep me updated on anymore challenges you come across that are not listed in MW2 challenges section. Would be nice to get this sticky'd!

+Rep if you wish =]

Do you have this title? Could you help me anybody to get the STD title.
GT: AZN Mind Tricks

where has the std and infected come from? do they randomly generate one in a million profiles to start with it or something? do the mods start with it and then spread it?
