Baden of WGB tackles the Knightfall ending: "The ending to Batman: Arkham Knight is slightly mysterious, to say the very least. No, not that one. The other one. No, the other other one. The one that you can only obtain by completing everything in the game, including finding and solving every single Riddle spread throughout Gotham, a slightly daunting task which is why so many people have opted to instead view the Knightfall Protocol ending on Youtube. Exactly why Rocksteady opted to have three tiers of ending is beyond me, because frankly the first two are a bit pants, and the true one should have been shown to everyone."
