I searched through the tag list for "Blood" and none of the results were for Bloodborne. I even searched through the new tags page as the game came out yesterday the 24th but I couldn't find a tag for this game. Could someone add it for me please?
If you ask a question about it and can't yet create tags yourself, someone can create the tag for you on the question if you let us know it needs it. Otherwise, it will have to wait until someone asks a question about the game - tags are only created when they are used on a question.
