"And if the next map would be located in Ypres, Northern France/Belgium, the word will be T.E.D.D.Y"

If you're basing the acronym off of where it's set than you would lose all the letters before the Y since those locations lack any of the letters you need. You can't really say there's a a connection when you have to pick and choose which words you want to use for your acronym. Otherwise I could state that PTRS is the magic acronym since they added the Peacekeeper, Tommy gun and Raygun Mk II and the next map must have a gun that begins with S.
