I am finishing up on the Hanger chapter, there is one area where you are on a pipe rounding it and you drop down to get around a rock that is in the way, you do this to get to a container on the other side, This could have had a nice surprise in it, it didn't have to be a trophy or achievement, but a Cap bobble head or something and make it worth a little more than 100 for an enemy film canister, though putting a schematic or Zola film would have been nasty!
