Amnesia the dark descent - Good Ending

The good ending of Amnesia the dark descent.

Wait for Alexander to prepare the portal. As he makes his speech it will get
more and more power. Keep a close eye on it. When it opens take AGRIPPA'S HEAD out of your inventory and place it in the portal. The shadow will consume Alexander and Daniel both, but you'll find yourself floating in a void. Agrippa's voice can be heard amidst the darkness, asking Weyer to help you. He tells Daniel that everything will be alright and the screen fades to white as the credits roll.
