hey i read your post in the batman platinum difficultly thread and i dont think you should give up....the combat challenges are really about keepin you combo up....go slow and make sure u counter everytime its possible and use as many of the nine moves as possible...all nine is a 5000 point bonus, and in the levels where they can get guns, as soon as the alarm goes off get over there and dont leave....and the throw move is great when u have a high combo because u throw a guiy into three other and u can ground pound at least two of them safely and that 100xyour combo in points....it may have took me only 5 days but i put a good amount of time into learning the combat system while in the story mode...good luck
