Six Terrifying Scenarios

"The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age." —H.P. Lovecraft, "The Call of Cthulhu"

A Night at the Opera collects six Delta Green operations that were previously published only in PDF or in standalone paperback modules. Combined, they expose a team of Agents to the edges of the horrors of the world of Delta Green, then suck them into abysses of fear and desperation from which the world itself may never emerge.
