Missing Mission???

[Slayer4000X2008]

I was reviewing the missions I had achieved to get the Warfield portrait. I noticed a mission requirement called "Piercing the Shroud" or something like that. So when I went to go find it and do it on normal it wasn't there.

So what I was wondering is, has anybody else had this problem, or is that actually required?

It is what im talking about, and thanks to Narks I was able to find it (went and googled the secret mission), I have now finished it and can get my Warfield portrait (soon).
