@3rd street saint.
Sounds silly but you done the game on hard, got all upgrade weapons and got gold on all the challenges. To see how much you got to go when you go and choose your saved game it will tell you what % you have done the game. I had same problem thought I did it but was on 99% nd did not get gold on 1 of the challenges.

okay i googled it, and it appears that you must beat the campaign on ANY difficulty (Big Bang) you must solve every riddle (Crack the E Nigma), find all tapes and all those cockroach things (World's Greatest Detective) and beat both predator (Predator Gold) and combat challenges (Fleefow Gold) then youll get 100%

The story mode is really not that difficult on hard.The problem most people have is Shock n Awe Extreme. Now that is hard. I found a great tip for this which helped me more than anything.
I was getting all the points I needed on the first 3 rounds but couldn't manage to finish the 4th round in time. At the start of the 4th round equip your exploding gel and run straight for one of the side platforms. Gel the floor and all the thugs will climb up and hit the gel together. Now ground takedown like your life depends on it. You won't take them all out in one go but you can get over to the other platform and repeat. I couldn't have done it without this technique. Hope that helps people

i just done this last night... i played the game on hard.. solved all riddles to upgrade my weopens.. when u play on hard the counter notice doesnt appear above the thugs heads.. so get used to playing the story on hard and try and perfect the freeflow perection actievement.. and then wen u have done story on hard..jump straight to the combat challanges and try and keep ure como as high as possible.. and the second you get your combo number flash yellow press A+X together to grab the knife or electric thug and try and throw them out the ring so the standard thugs are left to make it easier to gain a hhuge combo.. i kno its easier said than dne.. but im only trying to help

Read the roadmap to 1000 on the forum, it helps with challenges and lets you know about the 2 achievements you could miss, one right before the final fight with joker and his mutants.

I actually finished all of arkham city first.. and now I'm doing arkham asylum. I heard its easier.... So far so good. Anyone know if difficulty matters for this? I don't want to do all this Shit then find out later I have to do it all again on a save with hard difficulty..... ? I don't think it does but to be sure ya know.
