Gearbox Software released the demo for Duke Nukem Forever today, though it's only available to preorders and other promotions for the time being. After more than a decade, it looks like this game will actually hit stores this month. After 12 years in development, will it live up to the hype?"
Included with the linked article is DNF's launch trailer. This should go without saying, but just in case: NSFW. Seriously.
