I was playing Batman: Arkham City yesterday, and I found some fun little details in the city that I never noticed before.
Dr. Leslie Thompkins is one of Bruce Wayne's confidants in the comics, and runs a medical clinic for Gotham's addicts and criminals in the slums.
As you can see in the top picture, when you look at the police station from a certain distance away, it looks like the Bat Signal is on, but when you zoom in, or move any closer, it turns off.
After Batman and Freeze finish fighting over poison antidote, and discover that Harley Quinn stole it, you can see the hole in the wall she made to take it out of the safe.
I thought it was funny to see an Arkham mug in the GCPD, as I would expect the Gotham police wouldn't have cared for the place (what with it's lax security and all). Somebody start making these for real!
And here's another pause screen!
