CALL OF DUTY
Did you change the difficulty? It only unlocks when you click New Game -> Super-Hero.
You cant just replay all levels on super-hero difficulty, you have to start a new game and select super-hero difficulty.
I finished it yesterday on super-hero difficulty to get the last 2 achievements (vigilante and spider-man, i usually play games on easy first to get to know the controls etc). Both achievements popped up after the chapter 13 intro where you watch TV.
