Wow how did I miss this one, set in an alternate-history Metropolis the designer is Viktor Antonov, who did City 17 from Half Life 2.

Arkane co-founder Raf Colantonio is playing his new game all wrong. This is the first time I’ve had a first-hand look at Dishonored, the immersive sim from folk who’ve worked on the likes of Deus Ex, Half-Life 2 and Dark Messiah: Might & Magic, but I can tell you, right now, that one of its creators is playing it wrong. At least, that’s what my brain’s screaming at me. And I, too, am wrong.
