""Cthulhu Live is a live-action roleplaying game (LARP) version of the popular horror roleplaying game Call of Cthulhu. Based on the bleak works of horror author H. P. Lovecraft, Cthulhu Live is an action-oriented game that has been seen as an alternative to LARPS like Vampire: The Requiem.
Created by game designer Robert "Mac" McLaughlin, the first edition of the game was published in 1997 by Chaosium. A second edition and four supplements were published over the following years by Fantasy Flight Games. Its third edition was published in September 2006 by Skirmisher Publishing LLC, which has supported it with a Companion CD-ROM, a number of ready-to-use scripts, and a section of the company's interactive forum.""
