(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 =]

Nice,I only knew about the edge and radiation sickness,thanks for these!

No problem, please keep this updated with more challenges you find!

I can confirm "Completely Numb", "Living Dead" & "The Avenger" 1000% without a doubt, Go ahead & bold 'em.

What about titles? Any confirmation on titles to go with them?

Yes, Living Dead has one with some zombies... & completely numb has some weird purple one, I'll try and find em.

No worries, I got them, I wasn't sure if that's where they came from though, thanks for the help!

Two more.


If you stab someone that has the STD title selected you complete the challenge

STD infected you get 1000xp and the STD title

------------------------

If you get stabbed by someone who is using the infected title you get

Infected 1000xp and the infected title



Thanks for building this list, im always trying to figure out the extra hidden challenges.

loner (10 kill streak not equipped) also gives you the 8 bit black mario emblem.

actually avenger is a bonus like long shot and payback
