From introduction: The Chaos Iteration is a Cthulhu Rising adventure for a small group of investigators, with the requirement that one of them is a Computer Specialist, having a background in computer hacking / security. The corporations involved in the adventure are Hallidor Corp and Cenargo Corp, but feel free to change this to suit your own campaign. The adventure starts with a plea for help from a hacker friend of the Computer Specialist Investigator. If they respond, they will soon be drawn into a web of intrigue, involving industrial espionage, two rival corporations, a piece of software called The Chaos Iteration, and a group of Nyarlathotep cultists.
