How to defeat the White Witch  -  After Edmund is injured by the White Witch, you will be playing as Peter. Defeat all her enemies and walk over to her. When you hit her a few times, she will kneel and it will look like she's dead. She is not. If you walk away, she will attack you. When she's kneeling, press R and choose Unified Face in gifts from Aslan. Press B and Aslan will come and attack and kill her.
