Considering the gargantuan size of Rocksteady's final trip to the Arkhamverse - and their ultimate version of Gotham City within - fans were never going to be able to discover everything on offer within the first week or so of being on sale. True there's Easter Eggs, obscure side-missions and discussions on what works and what doesn't - but what about when it comes down to actually playing the game, 'being the Batman' in all his goon-scaring, cape-flowing glory? Well, Rocksteady left the best parts of that up to the user. Sure they'll teach you how to chain together a combo, how to sneak up behind some thugs and drop them in a flurry of brutal slams and screams, but the really juicy stuff is what fans have dug up after hours of experimentation and game-time. Not everything here is specifically a new combat move, though. Instead there's some hidden gadgets, a secret cutscene, a really slick interact-able easter egg and more. If you've discovered something in Arkham Knight that wasn't covered in the tutorial section or across the main campaign, let us know in the comments and between the thousands of gamers currently reclaiming Gotham bit by bit, we'll all be sure to do it in style.
