Requiem is the last level. Allow the credits to play all the way through. 47's body will be lowered underground. This level is playable. As the credits are playing, you can hear 47's heart beat and his health bar moving to the rhythm of his heart beat. As the credits are playing, repeatedly tap [X], [B], [A], [Y], [LT], and [RT] in any order. This must be done quickly. You will notice that his heart begins to beat faster and that his health bar rises. When his health bar reaches full, he will rise up and you will have control of him. The objective is to leave no witnesses, kill everyone.
