Kane and Lynch 1 was an abortion. I bought it used for 5 bucks, and still got ripped off. The combat is horrid, on the verge of unplayable. The camera, especially in co op, feels like it was done by an idiot. The cover system is ass, the AI goes from flat out retard to insanely cheap in the matter of seconds, etc.
K&L2 demo was basically more of the same, add a handicam, a little better graphics, and a lot of darkness. And from what I understand, 4 hours is flat out ridiculious for a single player campaign. What the hell were they thinking?
