Humble is giving away The Darkness II on Steam for PC and Mac during the next 24 hours. I played the heck out of the Darkness II demo on PS3 back when I first got my PS3 and that one level was incredible, even after playing it 15 times. I imagine it ports over well to PC and Mac and since it's not quite a cutting edge game, I imagine it will run extra well on your gaming PC.

"Inspired by the popular comic book series produced by Top Cow Productions, Inc., The Darkness II is an intense first person shooter that delivers a twisted and gripping narrative of tragedy, modern crime drama, and supernatural horror.

Players will be taken down the brutal and personal path of Jackie Estacado, head of a New York crime family and wielder of an ancient and ruthless force of chaos and destruction known as The Darkness.
