If you still need to pick up The Darkness II, you can get it for free for a limited time from Humble. For about the next two days, Humble is offering up the PC version of The Darkness II for $0.00 (USD).

The game also features four-player co-op if you're so inclined. If you would like to play the arguably superior first game, you'll need to pick up an Xbox 360 or PlayStation 3 for that. It sadly never made its way to the PC.
