Publisher's Note: A revised edition of this title is in the works for Summer 2021. If you purchase this version, you will automatically have access to the updated edition when it is released. You will not need to purchase the new edition separately. 


DoubleZero is a percentile based, skill-driven tabletop roleplaying system. It's a minimalist, 96-page core rulebook that contains everything you need to build characters and run an exciting campaign!

It is designed to emulate the action thriller genre, including things like the John Wick films, the Fast and the Furious franchise, and James Bond movies. You can dig into mysteries, procedurals, and crime dramas based on your favorite television series, from Law & Order to Murder She Wrote to The Sopranos. The system also draws inspiration from the spy novels of Len Deighton, John Le Carre, and Frederick Forsythe. That's not all it can do! The mechanics can be used for any sort of “realistic” modern setting that doesn’t lean into magic, the supernatural, or superpowers.

It is impossible to narrowly succeed at a difficult task. On Mx 5 every grade of outcome is possible. On Mx 4, Excellent, Above Standard, Standard, Below Standard, and failure are possible. On Mx 3, Excellent, Above Standard, Standard, and failure are possible. On Mx 2, Excellent, Above Standard, and failure are possible. On Mx 1 only Excellent and failure are possible. On those really hard shots, you always either hit the bullseye or miss the target completely.

You chance of an excellent outcome is independent of task difficulty. With a Dexof 12, you get an Excellent result on every Dex check regardless of its Mx.

Sorry, that last paragraph is garbled. It ought to read

"Your chance of an excellent outcome is independent of task difficulty. With a Dex of 12, on any Dex check regardless of its Mx, you get an excellent result if you roll 01–12."

Yes. That's how it's designed. It's so incredibly difficult that if you do manage to hit you're rewarded for the incredible luck of it with the best possible result. The intention is to be dramatic and cinematic. While it may not be to your tastes, it's not a flaw.

I'm sorry the system isn't for you.

Bought the print version and I really like it. I checked your website and here but did not see any sample characters or a sample adventure for DoubleZero. If you would upload a sample character or two, that would be great. A sample quick one shot scenario would also be awesome. Thanks for the fun game. I like how you used GORE as your System Reference Document.

I have just been trying to grasp the Fire Combat Rules ... and failing ...

1) I can't figure out what the Mx for a standard shot at a Range within that listed, but not within DEX Feet, is. Is it Mx3? Or what?

2) The rules state that attacks at up to double the weapon's range are at Mx -1, but the very next sentence states "Attacks against targets beyond the weapon's range automatically fail." These two statements are, to me, completely contradictory.

Which brings me to ...

3) Weapon Ranges. When I was in the Army Reserve we were equipped with SLRs (Australian made FN-FAL Rifles) which we sighted in to 50 meters, but which we were expected to be able to use to hit a target at at least 100 meters ... and which were sighted to, IIRC, 500 or 600 meters (which presumably would only have been achieved with an Optical Scope).

I guess the equivalent would be the .30-06 Semi-Auto, at least functionally, which has a range of 130 meters ... or 260...See more

Can I use these rules to play the scenarios made for James Bond 007 straight up?
If not, how much converting would I have to do?

It's not a straight-up retroclone. I'd suggest reading the full-sized preview, which has half the book, to get a feel for the system.

No, certainly not. The list of Characteristics is the same, but the range of characteristics is different. The skill list is similar but skills are binary instead of levelled, and Concentrations are a complete innovation. Converting NPCs will take a bit of work. Mx replaces Ease Factor, is on a different scale (1 to 5 instead of ½ to 10) and works differently, so tasks and checks will need to be converted.

If your goal is to play the published scenarios for JB007, then the "Classified" RPG from Expeditious Retreat Press would suit your needs much better. It is a retroclone.

Since the release of the DoubleZero Core Book, people have been asking for a mode that’s less gritty. Sometimes you just want to play something a bit more lighthearted and freewheeling, where the characters crack jokes as they succeed at tasks that defy physics. Easy Mode is meant to be used with that style of play, and more cinematic sorts of campaigns and settings.

The Easy Mode PDF has been added to the Core Book files. Previous and future purchasers can download it as part of the file set.

My reason so far for holding off on downloading was that I prefer a printed version. Now noticing that you are providing setting books as well, I might actually reconsider.

There will be print versions available eventually. The whole global situation has slowed everything down. It's taking 4 to 5 months for me to get packages, so I'm hoping the proofs will arrive for approval before the end of the year. No joke.

"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?
Customer avatar
Berin K June 01, 2020 9:33 pm UTC
PUBLISHER
You are correct. Outcome 1 grants 100% complete and accurate information. That table has since been fixed.

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)?
Customer avatar

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.

'Classified' is a straight-up mechanical retroclone of 'JB007', with only the following changes: "Ease Factor" was re-named "Difficulty Factor"; copyright material about the characters in the films and books,"M.I.6", and T.A.R.O.T. were removed; the weapons, vehicles, and gadgets were updated to the early 21st century; the NPC encounter table was re-written and expanded to use d10 instead of d6; the d6 used in the Draw rule was changed to a d10; notes (but not rules) were added about using the rules in other Thriller, Action, and Mysteries adventures and campaigns rather than James Bond operations.

'DoubleZero', on the other hand, has substantial differences to the core rules. Skills are represented in a very different way than in JB007 (there is no such thing as a PCS), Crucially, the core resolution mechanic works quite differently: it produces a lot more excellent results on difficult tasks, but does not let success chance go over 90%.

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.

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.
