DoubleZero Core Book


DoubleZero is a percentile based, skill-driven modern action thriller tabletop roleplaying game. You can be anything from a secret agent to a world-weary cop, a hard-boiled private eye to a petty criminal, a trained assassins to a victim on the run. Keep players on the edge of their seats with dramatic gunfights, thrilling chases, and nefarious death traps. Adversaries range from corporate sociopaths to organized crime rings, political terrorists to serial killers. Possible adventures span forensic investigations, solving cozy whodunits, foiling acts of international espionage, and uncovering vast conspiracies. Protect deadly secrets, handle ransom demands, or plan clever heists and cunning revenge plots. All manner of suspense and intrigue are possible with the DoubleZero Core Book.

For a brief, shining moment in the 1980s there was an officially licensed roleplaying game based on Britain’s most famous secret agent. While other people spent their youth playing Dungeons & Dragons, I was playing that. It had a quirky percentile-based core mechanic, eschewed heavy rules for a flexible minimalism, and was groundbreaking in its use of Hero Points to mitigate random die rolls and give players some control over their characters’ success or failure. My friends and I used it to run everything from 1930s pulp heroes to gritty police procedurals, action movie pastiches to sweeping historical epics. It remains one of my go-to game systems for any setting that doesn’t have magic or superpowers,

With the original being out of print for decades, it’s become increasingly difficult to share it with new players. I’ve tried to fill the niche with other games over the years, but none of have scratched the itch in quite the same way. Lacking a definitive alternative, I finally gave up and set out to write one. DoubleZero is less of a straight-up retro-clone than an homage and spiritual successor. It is similar in tone, but not identical in execution to that game.

"That other game" is were I started role playing and let's be honest, you never forget your first love. Classified is a pretty loyal recreation of that game, but I really like the way Double Zero streamlines and modernizes the original into something fresh and new. My only "complaint" (if you can really call it that) is that there is no "world building" to add thematic flavor. Of course the other side of that is that you can take this game in any direction that you want to go without wasting time wading through unwanted background information.
That being said, is there any plan for an agency or antagonist expansion?

The focus on the core book was rules. There are going to be setting books that offer different takes on how the rules can be used, which include agencies and antagonists. We just released the first, MOLOCH.

Comparing to Ghost ops and Covert ops what differences are in this game?

I'm not overly familiar with those games, but DoubleZero is designed for a wider variety of character types and adventures, not specifically focused on covert military operations. The first 48 pages are available to read in the preview, so you can make your own assessments.

I was looking through the preview and saw on page 10 (page 14 of the pdf) something that didn't quite make sense to me. The outcome table for Information appears to be inverse to other outcome tables. Why would an excellent outcome of 1 only grant 20% complete information and an acceptable outcome of 5 give full 100% complete information?

You are correct. Outcome 1 grants 100% complete and accurate information. That table has since been fixed.

Will you be including a preview option (quick or otherwise)?

Hmmm. I set up the preview to show the first 48 pages, fully 50% of the book, but it's not appearing now. It was working at launch. Let me check into that.

This sounds like sort of a retro-clone of James Bond 007. Is this similar or different than Classified (which IS a retro-clone of James Bond 007)?

From the description above: "DoubleZero is less of a straight-up retro-clone than an homage and spiritual successor. It is similar in tone, but not identical in execution to that game."

I'm not at all familiar with Classified, so I can't offer a comparison.

It is similar, but less focussed than Classified which is still very heavily structured like a Espionage/Covert Opps type of game, complete with shadowy worldspanning secret organisation detailed in the back as antagonists.
Double Zero is broader in scope. This is a system that you can use for any Police Procedural, Investigation, or Espionage/Covert opps game. CSI, NCIS, Hawaii 5-0, even The Laundry or CoC would be possible. It's kind of like Gumshoe I think, but with more action scene potential if nccessarry.

The SRD will be available at the end of June.

Print likely will not be available until autumn, due to the ongoing issues with business shutdowns, printer backlogs, and postal delivery details.

May I suggest you allow a hardcover print option, as even though the page count isn't too great, core rulebooks get a lot of use, and hardcovers just retain their looks on the shelf better, almost every softcover that I own, that has seen much use, has a curling cover.

One question, is the book entirely black and white text with no illustrations, as shown in the full preview?

The book is exactly as shown in the preview.

Original electronic
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.
