Batman: Arkham Knight – 9 Things You Didn’t Know You Could Do

5. Spot Arkham Asylum & Arkham City From Wayne Tower

There are easter eggs the way most developers do them - an obscure reference here, a doll of another game's character there - and then there are how Rocksteady handle things; multi-layered jaw-droppers so perfectly tucked away you'll need Sherlock himself to help you out. Anyway, we've put together a bunch over here for your perusal, but one such brilliant nod to the past games requires you to hop over to Wayne Tower, ascend all the way to the top and peer out over the night sky. Across the harbour and away into the distance you'll spot Arkham Asylum, but on the right the now-defunct Arkham City lies still. A particularly brilliant detail is the central tower with its left side shattered, courtesy of the events of the last game. Considering AK's end credits are a montage depicting just how perfectly planned the trilogy has been along the way, this is a great way of showcasing such a thing in-game.
