Game: Batman: Arkham Asylum (2009)

When the Scarecrow's level-long boss battle begins, you don't even know you're fighting him. It even seems like there's a glitch in the game until the beginning starts with a devious twist. Fighting Scarecrow scrambles your perspective as if you were battling the fear-obsessed lunatic himself. Game controls act up. You don't know which way is which. Then, as the caped crusader, you must navigate a treacherous landscape of a poisoned perception. Dodge your fears and the Scarecrow's notice in your deranged mind's eye.
