this game is not nearly as bad as people make it out to be.  If you play the game on expert, it adds a lot more challenge. Playing on expert removes the secondary crosshair that shows where your bullet will hit, and makes the AI notice where you are and where shots come from much quicker. This means that you have to make your shots count.  However, it also takes away certain markers on your mini map that show enemy positions for some missions. Its in no shape a perfect game but it is an enjoyable one, especially for a budget price.
