Bought and finished The Darkness over the course of the weekend, and I have to say it's one of the best first-person shooters I've seen in a long while. It's also staggeringly violent. It's the only game that I know of in which you level up your character by eating your enemies hearts.
Good voice work and storyline don't hurt either. The developers have taken the brave and sensible step of redesigning almost everything from the comic. Makes sense, given that the comic was originally illustrated by Marc Silvestri, one of the many hacks that formed Image, and insisted on drawing in exactly the same style as Todd McFarlane, Rob Liefeld, et al. So, as a result the main character doesn't have a ridiculous superhero suit made out of 'darkness'. This can only be a good thing.
