Visceral Games artist "Joebot" has released concept pics (or so he claims) for an unannounced, cancelled Jack the Ripper game, titled simply "The Ripper". Looks like it would have been bloody good. Emphasis on the bloody.
According to Siliconera, players would have stepped into the shoes of the one and only Jack, tasked with ridding Victorian London of baldy vampires. Makes a refreshing change from gutting prostitutes, I guess.

Take a look at the shots. Concept artworks are rarely unattractive, but these are especially memorable. Almost Thief-ish. Cheers, VG247.
