    Aidenkael31. Should be armory, not infirmary :P Confused me a bit there.

    Blunt EastwoodYes
    Dossiers # 47 & # 48 are glitched. Well they were glitched for me and few others have said the same thing. I just started wrecked from the begging and picked all dossiers (42-48) up. But once I picked up # 45 the investigator achievement popped.
    This I believe only happens when have #'s 47+48 to find.

    Epsilon ThetaPlease include the location of the dossiers in your solution and not just the sub-sections they can be found in. All solutions should be able to stand on their own!

    finallife6I think the soultion is helpful enough as the top solution is just a big pile of info and no clearifying a simple thing like levels
