Modus Operandi is a roleplaying game of super spies and secret agents set against the backdrop of the Cold War of the 1980s.

Go back to basics and become an expert.

Modus Operandi is an espionage role-playing game in which you play an agent employed by a secret organisation working to stop those who would destroy or dominate the world. The default setting for Modus Operandi is the 1980s but your games can be set in any decade.

Modus Operandi is inspired by old school espionage games but, using the Old School Essentials SRD as its core, brings a fresh take to the genre. Included in Modus Operandi are all new character classes (called specialities), weapons, equipment, communications gear, gadgets and rules for contacts.

Available in PDF ($6.99), softback ($9.99), and hardback ($19.99). Print editions come with free PDF (if you forget to select this option, please let us know your order number and we can arrange for the PDF to be issued to you).

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.
