Understanding the Delta Green Mythos

The Guide details the origins of these beings, their influence on human history, and the insidious ways they manifest in the modern world․ It emphasizes that the Mythos isn’t merely about monsters; it’s about the erosion of sanity and the unraveling of reality․

Knowledge, in Delta Green, is often a curse․

Majestic 12 and the Great Old Ones

The Delta Green: Handler’s Guide (available as a PDF download) meticulously details the fraught relationship between Majestic 12 and the terrifying Great Old Ones․ From February 25, 1994, to March 2, 2001, Majestic 12 waged a secret war against the encroaching Mythos, a conflict extensively documented within the Guide․

Furthermore, the PDF download illuminates the roles of various support organizations, providing Handlers with a deeper understanding of the resources available to their agents․ These include research facilities, safe houses, and logistical support networks․

Delta Green Cell Structure

The Delta Green: Handler’s Guide, available as a PDF download, dedicates significant detail to the organization’s cell structure․ It’s revealed that Delta Green operates through a deliberately decentralized network of autonomous cells, a direct response to the vulnerabilities exposed during its conflict with Majestic 12․

The Handler’s Guide PDF emphasizes that cells lack direct oversight from a central authority․ Instead, communication flows through indirect channels, utilizing coded messages and trusted intermediaries․ This adds a layer of complexity for Handlers, requiring careful management of information flow․
