Can we trust our senses? How do we know that what we see is real? Are our eyes inherently deceptive and prone to misdirection? If so, then such flawed organs must be removed, for only in blindness can one perceive the truth: that all the world is horror. Sight Unseen is a LARP experience like no other. When an assortment of Arkham citizens check into the local hospital for surgery, they find themselves blinded by a madman and forced to confront the unearthly terror he has unleashed upon the world. Sight Unseen is a game script for Cthulhu Live 3rd Edition and requires the Cthulhu Live 3rd Edition game rules. The text contains the game overview and timeline; detailed guidelines for simulating blindness in LARP, including safety precautions; prop, special effects, and stagecraft techniques designed to play upon your player's senses of touch, smell, taste, and hearing; and detailed character sheets and backgrounds for seven player characters. Ideal as an event for a Live Action Role-Playing (LARP) party with friends or as a convention event, it offers hours of fun, intrigue, and horror.
