Here is an interview with the Creative Director on Darkness 2 at E3 2011. As you can see it is very dark indeed, but after getting a look at the sequel, I was very impressed by the style of it. The whole game just feels more evil than the first one, mostly from the new visual style but from other elements as well. I would love to share more on what we were previewed, but I saw so much this year that it was mind blowing, but I will be posting more on what experienced there soon enough.
