It looks a little Bioshock-y. I assume some of that is the use of the Unreal engine...
I don't think it looks anything like broshock & I am wondering why you think that? The art style is completely different.
Now lets see what info we can pull from this shot. It has a flintlock pistol so that suggest some kind of Renaissance setting mix that with the cover and I say we might be looking at a steampunk setting (The crane also looks like it has a motor on it).
Can anyone tell what is behind the guy? It kind of looks like wrapped bodies, but I can't tell for sure.
The mask suggest the old trick of putting a mask on someone so you don't have to animate their lips.
There is a what looks like a water tower in the back. I can't think of the last time I saw a water tower in a game, so that kind of makes me think we will have some kind of power to use on that water tower. Maybe exploding it or doing something with the water in it.
