Batman: Arkham Knight – 9 Things You Didn’t Know You Could Do
4. Find Batgirls Costume
Many of the easter eggs across Gotham are verbal references or visual in nature, but considering you only visit the Clocktower a couple of times with a very defined forward-facing objective, you might have totally missed accessing the console in the corner of the room instead. To do so, wait until the point in the story where you return to Wayne Tower and pick up the Remote Hacking Device, then dart back to the Clocktower and use it on the green terminal in the corner. You'll see the front panel drop down and reveal a small shrine (of sorts) to Barbara's time as Batgirl (subject of a future DLC pack) showing even though she's taken on a new life as Oracle, her past exploits as another of Gotham's saviours was never far behind.
