If you are about to die, just pause the game and hit the restart button, or if are already dead, hit the power button(sensor)immediately because if you don't do it in time, it wont work. Or if you hesitate but does not show the enemy, you may lose ALL your progress on the game. To avoid losing your progress, copy your profile on another storage device(like a flash drive or hard drive).
Big Head Mode
This feature is the same as the one in Arkham City Batman. To enable Big Head mode take out the cryptographic sequencer and hold L1 and R2 and rotate the right analog stick clockwise until Batman's head becomes big.
