Have you played the previous one, Bound in Blood? If so, you might be a little disappointed.
If you haven't played the last one and you like COD style shooters, you might like it, though beware... the f word is included in almost every (not exaggerating) sentence and can get a little old.
Overall, it is not as good of a game as the previous, its missing the clever dialog and amazing auto-cover system from Bound in Blood. (Why they didn't include it is a mystery to me!)
Try it out and see what you think, it's no COD or Battlefield, but it isn't bad, especially if you like co-op games.
If you haven't played Bound in Blood. Go find it for as cheap as possible, trudge through the first 3 levels (they aren't very good) then be prepared to be amazed at level 4 through the rest of the game. You'll definitely love it!!!
