Item description:

After searching for the last Batman AA: GOTY saves I needed and having no luck I ended doing them myself. So...

These are for those who need the following achievements on Batman: Arkham Asylum - Game of the Year:
Freeflow Gold
Predator Gold
Perfect Knight (100% Completion) [Easy difficulty]
and/or
Biggest Bang (Complete story mode on Hard difficulty)


If you need BOTH challenges in GOLD you'll have to do it OFFLINE because they'll pop at the same time screwing the timestamps. If only one challenge in Gold is needed then it's OK since Perfect Knight pops at the same time anyway.


****WHEN YOU LOAD THE 100% SAVE DON'T GO TO THE CAMPAIGN INSTEAD GO STRAIGHT TO THE CHALLENGES. If you go to the campaign Perfect Knight will pop regardless if you have done any challenge, making it look very "UN-Legit" in the order****


SAVE0 - 100% EASY - PERFECT KNIGHT
By completing any challenge you'll unlock ALL of the related achievements (BRONZE, SILVER & GOLD), but they'll unlock at the same time. I would recommend doing it OFFLINE. (I tested it once on a dummy account and they unlocked in order).
If by any chance you only need Perfect Knight the just load the campaign.

SAVE1 - 74% HARD - BIGGEST BANG
You're already in the fight with Joker. Just run away from him, beat his thugs and grapple him down for a beat down. Repeat if necessary since I can't remember how many more were needed.


Sorry for all the BOLD used, I just wanted to make sure it was done right and not screw anyone. Regardless you should try them on a dummy account following the instructions.
