Easter Eggs relating to Superman nemesis Lex Luthor and his home city of Metropolis have been uncovered with Rocksteady Studios' Batman: Arkham Knight. While not exactly hidden, they are reason enough for some rampant speculation.
Gathered together in the video made by Arekkz Gaming embedded below, the three Easter Eggs found so far range from the obvious to the seemingly innocuous.
The first Easter Egg is obvious – a large billboard for Lex Luthor's company Lex Corp hanging above Gotham City, promising hope for Batman's beloved city. The second took more work on the part of the developers, who hired a voice actor to play Luthor, who leaves a voicemail for Bruce Wayne which can be listened to at the top of Wayne Towers.
Luthor's voicemail doesn't drop any particularly juicy hints, he is just pushing Wayne to sell Wayne Tech's Applied Sciences division to him. That division being how Wayne amasses the arsenal of gadgets he utilises as Batman.
The final Easter Egg is a small poster for Metropolis – the famed city where Superman/Clark Kent lives. The location of it couldn't be found by the video's creators, but has been spotted and screengrabbed by other players.
In Arkham Asylum, the first game in its Batman series, Rocksteady included one of the best hidden Easter Eggs ever. A blueprint for Arkham City – the giant prison and back-up plan for if the asylum was to fall – could be found in the warden's office in a hidden area not on the map, giving away the name and location of Asylum's sequel.
The Easter Egg was so well hidden that it wasn't discovered until Arkham City had already been announced. If Rocksteady has left a hint at its next project in Arkham Knight, it is probably hidden slightly better.
That said, it could still be a hint that Warner Bros is looking to make more games about DC Comics superheroes. A Justice League game was long-rumoured, for Rocksteady no less, but has yet to see the light of day.
Batman: Arkham Knight is out now for PS4, Xbox One and PC.
