Batman: Arkham Asylum (Xbox 360) Walkthrough

7. 100%

This will be the last achievement you will get, but i will add a checklist so you can make sure you have everything in order before you start calling the game glitched for not giving you the achievement. Ok? So keep your wig on!

To achieve 100% you must:

  • Complete story mode on any difficulty, but hard is best.
  • Get every riddler trophy.
  • Purchase every upgrade.
  • Solve every riddle.
  • Find all the Arkham Chronicles.
  • Get gold on all combat challenges.
  • Get gold on all predator challenges.

After all of this, order a takeaway then the achievement will unlock, well maybe not the takeaway part, but you must be hungry after getting all of that, i'm just looking out for you.
