Several different websites for fictional organizations or individuals mentioned on the show or in part of the Lost Experience were introduced. The websites, particularly the Hanso Foundation website, contain background information into the mythology of Lost. The character Rachel Blake, also known as Persephone, is introduced to guide players through the game. Most clues on the Hanso Foundation website are revealed by clicking on faintly marked anomalies in the web page design or by entering specific codes into webpages. Some require passwords found elsewhere, such as in the voicemail service. The clue revelations are designed as minigames, though with little challenge as they are completely linear.
