Isn't it strange to think there's been countless video games based around Batman over the decades, but for some reason despite various games based on Batman Forever, Batman & Robin and even Batman Begins, there wasn't a game based around Christopher Nolan's seminal work The Dark Knight?
It's because that one was scrapped!
Not a lot his known about that game, aside from some concept of The Joker you can see above (which isn't directly lifted from the film actually) and that Heath Ledger even voiced some lines for this canceled game.
Some footage has finally been uncovered recently thanks to Unseen64, check it out:
In a way, it's a good thing we never got this Dark Knight game because we would be getting Arkham Asylum shortly afterwards. But it did seem to come up slightly better than the released Batman Begins game. How can we know, it might have been awful.. or actually been pretty decent.
But it does make you wonder...
