Batman: Arkham Knight - 15 Hidden Easter Eggs, References & Secrets You Need To Find

15. Superman's Many, Many Teases

It seems when Rocksteady mentioned they'd love to do another superhero game after Batman, there was more than a shred of truth to it. Not only does Lex Luthor appear in audible form in the campaign (more on him soon), but Gotham is positively littered with posters for LexCorp, NPC/thug dialogue discussing "that freak from Metropolis" - even occasionally mentioning him by name.

Could it be Rocksteady are aping their silver screen brethren by using the Arkham trilogy as a jumping-off point into a larger mythology, incorporating Superman into the mix along the way? Only time will tell, but considering how awesome the destructible city tech of AK is, it'd be a perfect fit for any superhero-flinging battles that'd leave any surroundings in ruins.
