In 1968, in response to sinister influences that threatened to corrupt America from within and without, the Federal Government established a new agency – one that quickly acquired a reputation for ambitious operations overseas, for covert action, and for doing what had to be done, no matter the cost.

This new agency was the Bureau of Narcotics and Dangerous Drugs, the BNDD. And within it – the forces of DELTA GREEN.

Hunt the Unnatural across the world! From the opium fields of Laos to the skies above the Pacific, from Turkish smuggling routes to the secret heroin labs of Marseilles, follow the trade in misery and fight the horrors along the way. Expose the criminal underworld – and discover that it’s inextricably linked with other secret realms.

The Borellus Connection is a campaign for Fall of Delta Green, using the heroin trade and the United States Bureau of Narcotics and Dangerous Drugs as a narrative spine. The campaign runs from South-East Asia to the Middle East to Europe, as the Agents uncover the sinister machinations of a necromantic cult.
