Forum:Curiosity of new secrets

I am amongst one of those people that enjoy exploring new levels to figure things out but I'm not having to much luck as to finding much so far I've found that in K.D.T there are portraits of the team dempsey, nikolia , takeo and richtofen but there are 2 blank portraits as well ( personally raises questions) there are also stacks of paper through out the level on podiums , in crevices now normally I wouldn't notice stacks of paper but I have learned that if something is irrelevant it's normally stationary and they don't appear often now shooting or stabbing these papers disrupts them i have still yet to find them all I think but there may possibly be another small secret behind them like apparent perk upgrades like in w.a.w or music if anyone else has any small things they have found I love to hear about them to test new theories please add my gamer tag (xbox) or add to this post?
