The Darkness 2 has a release date, October 4, 2011. The Darkness 2 continues the story of The Darkness, released in 2007. The series draws from the Top Cow comic series of the same name. The Darkness 2 picks up two years after D1 as Jackie Estacado has advanced to Don of the Estacado crime family. The game boats Quad-Wielding gameplay, and they trade-marked Quad-Wielding, that's how serious they are about it.
The Darkness 2 will be released on the Xbox 360, PS3 and PC.
Side note: I've named his two shoulder-demons Flotsam and Jetsam.
