The Cepheus Engine RPG  comprises the core rules for a Classic Era Science Fiction 2D6-Based Open Gaming System. Inspired by the original three books of the oldest 2D6-based science fiction roleplaying game, the Cepheus Engine system incorporates elements of Open Game Content from previous releases of that game of intergalactic drifters and wanderers to create a basic system that will allow players and Referees alike to create their own science fiction universes or play in the ones they are already familiar with.

You'll find the core essence of your favorite sci-fi game here. You can explore interstellar space, make a ton of Credits on speculative trade, find yourself halfway across the sector after a serious misjump, or blow people up with your mind, if you can find training. You can even die during character creation. This stand-alone manuscript provides all the rules you need to play the game. The Cepheus Engine rules were intentionally designed to integrate well with other 2D6-based science fiction gaming systems, especially your favorite Classic Era modules and supplements. All of the material in the Cepheus Engine rules is considered Open Game Content.

Please note this set of rules is the same as the Cepheus Engine System Reference Document.
There are a few minor changes and fixes. It also includes a blank character sheet, blank sub sector sheet, combat reference sheets and a complete index. There is no internal art, except for the cover art and the blank sheets.

Jason Kemp has kindly let Moon Toad produce this edition with his permission.

Hi there--

On p. 46, the Common Personal Armor table shows Cloth as TL 6, Mesh as TL 7, Vacc Suit as TL 9, and Hostile Env Vacc Suit as TL 12; but the Armor Descriptions have them as Cloth TL 7, Mesh TL 6, Vacc Suit TL 8, and Hostile Env Vacc Suit as TL 8.

Thanks for spotting that one. The text descriptions are correct and not the table>
I'll get the PDF fixed as soon as I can.

What's the difference between this and the SRD? What are the "minor changes and fixes"? How come this edition has a smaller page count? Does the author get any money from the sale of this edition?

Sometime ago I mentioned to Jason about doing the POD version, he unfortunately had no time to do it. So the deal was I would do it and publish it under Moon Toad - so any $/£ from the sales pays for my time doing the work - 170 pages of layout, a cover, subsector/character sheet and a few edits - plus an index (I paid for) He is good with this.

Minor edits/changes, to be honest no much. But I need to get a list up to say what is different, nothing earth shattering or radically alters the SRD

Let me see:
Prospecting skill added, this is missing in the SRD
Spinal Mount skill - added a line about saying Spinal Mounts would be covered in a future supplement
Vehicle cascade skill list- better organised - ground vehicles now belong to a sub cascade group
Vehicle List - this now matches the CE Vehicle SRD
Ship Design - minor clarification about software and computer capacity.
Under Sciences skill description, changed "types of planetary transportation"...See more

One other thing.

Aerospace System Defense is now Aerospace Defense
Maritime System Defense is now Maritime Defense
Surface System Defense is now Surface Defense
These where like this in the skill tables but not the Career descriptions list. (bit of a contradiction)

Perhaps of interest to those reading it on a phone. The text has been reformatted to two columns (form 1 column in the original Cepheus) so it's much easier to read.

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.
