The story of Vaas and Jason isn’t the only tale to be told on Rook Island. The Letters of the Lost offer an insight to some of its previous inhabitants as various soldiers from WWII, and a man named Hurk, have left their thoughts and memories scattered about in the form of letters. There are twenty different letters that can be found on the bodies of dead soldiers that tell a disturbing tale of things during their time on the island. It’s an interesting tale, but to get all of it, you’ll need to find each of the hidden letters. If you are having trouble locating some of them, or you just want to save yourself some extra coin by not purchasing all of the maps, we have each and every letter found and marked out to make life easier and to get you the Dead Letters Achievement and Trophy.
