In space nobody can hear you scream... but that doesn't mean that there isn't something to scream about. Although they can arise anytime, anyplace, in some ways zombies are science fiction, with Frankenstein being regarded as the first science fiction novel. This book is the science fiction sourcebook for All Flesh Must Be Eaten, with new rules for creating characters and playing in science fiction settings, five full-blown settings and a whole bunch of other ideas. After explaining this, Chapter 1: Introduction runs through the standard conventions of presentation, and provides an extensive list of books and films to mine for inspiration.
Next, Chapter 2: Starship Shamblers provides specifically science fiction rules to enhance your game, starting off by defining various technology 'types' or broad classifications - biotech, cybertech, space travel, nanotech and the far reaches of space opera - that can be used to categorise your game. It then looks at character creation, noting that standard characters do just fine but you may want cybernetic enhancements or something, ot play a non-human alien sentient. There are rules to accommodate all that, along with new skills, qualities and drawbacks appropriate to a science fiction game. You can even be a robot - at least you won't have a 'brain' for zombies to munch on... and this presents the interesting concept of running a game where it's robots rather than zombies which are on the rampage!
And now on to the full-blown settings. The first is cybertech mixed with Mad Max. Then there is one in which nanotech gone rampant leads to the fall of nations and a resurgence in religious belief, followed by an Aliens style setting in which the party is sent to investigate a colony which has gone silent. Another is purely virtual, taking place in a digital realm... but you cannot escape zombies even there, and finally there is a space opera setting complete with warring empires. Plenty there to choose from - but if that's not enough, there is a selection of other ideas that will need further development but could do nicely for a short-term game even if you don't want to build them into a full campaign.
There's no reason to leave the zombie menace in the past. Encounter them in the future, on other worlds as well.
