God of War is an enormous game, so it's likely that there are plenty of secrets hidden throughout it. But what few people could have guessed was that there'd be something revealed by clues buried in the physical map that came with the Collector's Edition. (Warning: some spoilers below.)

As Kotaku reported, players have now unraveled a puzzle that stems from runes scattered across the Collector's Edition map. These runes were deciphered by YouTube user BRKsEDU, who used in-game alphabets to assist in the transliteration. You can read the full runic riddle at the bottom of this article; essentially, it recounts the tale of Sindri and Brok and their journey for treasure.
