Delta Green: A Night at the Opera


ENnie Award Nominee for 2018: Best Adventure and Best Electronic Book!

“A Night at the Opera” collects six Delta Green operations, or “nights at the opera” as agents sometimes call them. Each scenario stands on its own as a moment of terror. Combined, they expose 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.

  • REVERBERATIONS: An introductory scenario in which the agents confront foes that were old before Delta Green was born.
  • VISCID: Investigating a geneticist’s gruesome death, the agents face lethal conspiracies and uncover horrors that never should have been made.
  • MUSIC FROM A DARKENED ROOM: The agents must investigate a house that may be haunted by things more terrifying than ghosts.
  • EXTREMOPHILIA: Can the agents stop the spread of an unnatural threat? Or will they become just another vector for the disease?
  • THE STAR CHAMBER: The agents must hear and adjudicate the horrific after-action report from another team—by way of playing out scenes from the earlier mission in between scenes of the present day.
  • OBSERVER EFFECT: The agents investigate a cutting-edge physics laboratory that may have looked a little too deeply into the nature of reality.
  • An index helps the Handler build broader connections between horrors in the campaign.

A Night at the Opera is playable with Delta Green: The Role-Playing Game, an award-winning update to one of the most acclaimed RPG series of all time: the Agent’s Handbook, the Handler's Guide, and the free quickstart rulebook, Need to Know.

FYI The "Reverberations" bookmarks are duplicated inside Viscid.

If I own the individual pdfs of all six adventures, am I missing out on any content in this book?

Only the index, that lets you put the adventures together easier. I dont think its worth buying it if you have all the parts that it's made of, though I dont have this version, so I cant tell you what the index is like.

I don't think so. My PDF version that I bought here has the index.

Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
