Yea, I didn't think it was that bad of a game, but I'd say rental or Gamefly only. I will say that I have played worse games on the 360, but I think that list only includes Hour of Victory, Raven Squad and Damnation.
Mickey Rourke does the main characters voice and his comments are so over the top that the first play through is entertaining enough and short (4-5 hours on the hardest difficulty). You will spit out your drink when you hear him yelling "Lick my Balls" to the bad guys while in "stealth mode" at the beginning of levels.
If you want a full 1000 you have to do 3 playthroughs because difficulties do not stack, but you can fly through in a couple hours on the easier difficulties and there are only 8 missions. There are MP achievements that you need 4 people for and one you need 5 for which you will need to boost with friends.
