Investigator Weapons for Call of Cthulhu in the Classic era is a comprehensive collection of weapons available to stalwart investigators of the Cthulhu Mythos and their crazed cultist opponents.

Investigator Weapons covers handguns, rifles, shotguns, submachine guns, machine guns, flamethrowers, melee weapons, explosives, and special ammunition; and gathers together all the spot rules for injury, environmental conditions, and firearms combat in one place, as well as introducing many optional rules for enhanced play.

Hans-Christian Vortisch (author of Cthulhu – Waffen-Handbuch, GURPS High-Tech, GURPS Martial Arts: Fairbairn Close Combat Systems, and GURPS Tactical Shooting) has selected several dozens of the most typical or iconic weapons available to the discerning shooter in the 1920s and 1930s. These range from the famous Colt M1911 and Thompson submachine gun to lesser known but more widespread firearms.

Each weapon is illustrated and described in detail, as are variant models. Significantly, each weapon’s operation is described, as are its typical malfunctions. Finishing each weapon description is the movie use of the weapon – so you can see it in action – and a comprehensive statistics bar.

Keepers are not forgotten either. Typical weapons for non-player characters are suggested, as are likely weapons for cultists from around the world. A Keeper’s chapter examines the consequences of magic on firearms and ammunition, and the effect of firearms on Mythos creatures.

Investigator Weapons – the essential weapons book for Keepers and players of all editions of Call of Cthulhu.


Also included in this purchase are separate weapons summary charts, weapons record sheets, and a rules summary sheet.

The book is available as PDF and POD from this site. A softcover edition is available in games stores.

This is what some reviewers had to say about Investigator Weapons:

“Maybe it’s the history buff in me or maybe I just like old weapons more than I thought. Whatever the reason, the angle this book took won me over ... I didn’t want to like this book, but I did. I think fans of the game or weapon buffs will too.” ‒ Todd Cash (Flames Rising)

“The obvious amount of scholarly research that has gone into this book is truly awe-inspiring. Despite the fact that I’m probably less fascinated with firearms than most (both in real-life and in Call of Cthulhu), I can’t help but agree with the sentiment that this is destined to be one of those “must have” books for Cthulhu gamers. Keepers interested in injecting additional realism and danger around weapon use will find plenty of stuff here ... as will players who (perhaps foolishly) seek more firepower to combat the forces of the Mythos.” ‒ Dean Engelhardt (Cthulhu Reborn)

“The style of writing is witty and engaging with just the right tempo without reverting to a stiletto style. Lavishly illustrated with loads of real world photographs and period piece advertisements gives the impression that one is flipping through the Sears Roback [sic] or equivalent from the day.” ‒ Kafka (

My group loves this book! The core CoC rulebook is a bit sparse on available weapons, so we really appreciate the expansive roster and meticulous detail on how the guns all differ. This sourcebook doesn't skive on any details; you'll know eve [...]

If you want an expanded weapons list plus some alternate rules for combat this is a great product. I found this works well with Pulp Cthulhu and it gives those students of history, which many who play this game are, a reward for their erudition and ent [...]

A well written and presented example of that rarest of things; a Call of Cthulhu supplement that you can give to players. HKV has been producing quality work for Call of Cthulhu and GURPS for years and this is no exception. I particularly liked the sug [...]

I am intersted in running a First World War scenario, and I decided to try this product in the hope that it would have statistics for the weapons of the First World War. This supplement has detailed information on weapons and new firearms rules. [...]

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.
