This stealth/adventure game series was developed by Frictional Games. There are things I need of you. Things you may not understand, and may not wish to do, but please, do not make the same mistakes I did. My father, Howard, sent me a letter last year that led me into all this. To think that such a small event can change your life in such a violent way. Without this knowledge, without this foundation, you could not have the will to do what I must now ask of you.
