Horizon Forbidden West's Burning Shores expansion has been out in the wild for a while now, and though plenty of players will have seen credits roll, none have achieved true 100% completion... although it wasn't for a lack of trying.
A single missing Brimshine crystal prevented some players from crossing that imaginary finish line each of us draws in our minds. While it's perfectly possible to play through all of the DLC content, it was not possible for the truly dedicated to buy and fully upgrade everything in a single playthrough and thus achieve true 100% completion.
Will you be righting this wrong the first chance you get, officially removing Forbidden West from your backlog, or have you already moved on? Make a careful accounting of things in the comments section below.
