This massive, full-colour volume is filled with deep resources just for the Delta Green game master.
The Past: details on the world and history of Delta Green.
The Unnatural: details on the Cthulhu Mythos, from monsters to hyper-geometry to the Great Old Ones, including rules for creating new threats.
The Schism: deep details on the Delta Green organisation itself -- or rather, two different Delta Green groups, not always working to the same ends.
The Opera: guidelines for creating scenarios, running campaigns, and customising the setting.
Appendices: a ready-to-play scenario, The Sentinels of Twilight, a Handler-facing glossary, index, recommended media, sample NPCs to use in any game, rules variants, and more.
