PDF + Softcover, B&W Book

The bombs fell. Nations wielded varied and monstrous weapons against one another. Fires, clouds of poison, and worse have swept the world. Now only the savage Wastes remain: haunted by mutants, deranged robots, and genegineered monstrosities. But from the fire, heroes and villains rise: tribals, survivors, mutants, all the warped remnants of Humanity. Armed with primitive weapons, pre-Collapse artifacts, and afflicted by strange mutations, they set forth to conquer the wastes, or at least to survive them. By spear and laser, they shall prevail – or die a horrible death.

Cepheus Atom is a lightweight role-playing game where players assume the roles of survivors exploring a sci-fantasy post-apocalyptic world. This is, as some people call it, a “gonzo” apocalypse – expect sentient mutant animals and plants!, death-ray guns, and wild mutations, rather than the grimmer darkness of a more realistic apocalypse. The rules are designed for fast, “beer and pretzels” play, where players roll dice and blow up stuff between bites of pizza and sips of soft drink, all while enjoying an evening with friends.

All you need to play are this booklet, a few six-sided dice, writing supplies, and your wild, mutated imagination!

Cepheus Atom is compatible with Stellagama Publishing's Barbaric! sword & sorcery rules. Bring dark sorcery to your post-apocalyptic wasteland! Pit your atomic survivors against mythical monstrosities! Arm your barbarians with laser rapiers!

How long is it supposed to take to heal lifeblood before a severe wound?

Can you play it solo?

There are no solo rules in the core Cepheus Atom rules, but we are considering publishing a solo-play module in the future.

Hmmm ... as a post-apoc nut I am curious. Looks good, but starting PCs are just not wild enough ... need more mutations, and animal, plant and machine player characters. Is that in this?

We are considering publishing a short supplement with even more gonzo options, such as sentient animal and plant player characters.

A note to all customers - We have completed the Cepheus Atom print layout and uploaded the files for the print process. Fingers crossed, the print version should be ready in a short time.

This is a fantastic PA game! Amazing content for the price!

I actually find the progression through accumulation a great concept, and so it is in this vein that I'd love to see a "settlement" or "sanctuary" supplement! A way of building a home through adventuring and scavenging the wastes.

We will definitely consider writing a "Sanctuary" supplement.

Where are the rules for experience gained?
Customer avatar
Omer J August 19, 2020 8:13 pm UTC
There are no rules for experience at this scale; your character develops by mutating and hoarding pre-Collapse technology. Skills are a big deal, and thus a one-point increase should be rare, and characters already start competent at the end of character generation. If you want skill advancement, allow the character to gain one skill point per in-game year (or 5 adventures). Again, this would be a major change in character abilities.

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.
