Welcome to America at the end of the millennium. Do you know who is pulling the strings? Delta Green knows. Things from beyond space and time that lurk and titter in the shadows, the slow rot at the core of humanity, the dark stars that whirl madly above—these are the true masters of the world. Delta Green has been fighting since the 1928 Raid on Innsmouth, and the fight rages on. This book is your weapon and your guide. The Conspiracy resurrects Delta Green, the smash hit sourcebook that launched decades of horror.

The Conspiracy updates the groundbreaking Delta Green in a new, full-color hardback. It is edited and revised for Delta Green: The Role-Playing Game, restructured, and filled with beautifully dreadful new illustrations. This 1990s sourcebook presents government conspiracies, alien activity, undead Nazis, and much more through the lens of Lovecraftian cosmic terrors. And it details Delta Green itself from those lost days: a handful of men and women who use the resources of the government to fight a secret, illegal—some would say treasonous—war against monstrosities which threaten their world.
