F.3.A.R. and Fracture developer Day 1 Studios was once at work on a Batman game based off the one-shot Gotham by Gaslight comic. Well, to pitch, at least.
The game was never greenlit. It was intended for PlayStation 3 and Xbox 360, sometime between 2009 and 2010, and saw Batman track down Jack the Ripper in a foggy 19th century open-world. He had the ability to see in the dark. THQ was meant to be the publisher.
