Retrospective: Kafer Sourcebook

For reasons I'll explain in an upcoming series of posts, I've been thinking a lot about GDW's other science fiction roleplaying game, 2300AD (né Traveller: 2300). As I've no doubt explained on several occasions, I was, for a time, a huge fan of the game and – especially – its setting. Truth be told, I still am a fan, even though I've not played the game in almost forty years. One of the things I've always admired about the game was its commitment to a plausible and "realistic" approach to the building blocks of its setting, whether scientific, technological, or political. Unfortunately, that same commitment has also probably contributed to my inability to ever sustain a 2300AD campaign.

Emblematic of the problems I've always had with the game is, ironically, one of its best supplements, the Kafer Sourcebook. Published in 1988 and written primarily by William H. Keith, Jr, it's a deep dive into the society, culture, history, and, above all, biology of the alien Kafers, humanity's only serious interstellar rival. It is a 96-page softcover, though it feels longer, due to the sheer amount of terrific science fictional speculation packed into its chapters. Even within a product line celebrated for its world-building rigor, this book stands out for its imagination and ambition.

Remember that, when 2300AD debuted in 1986, it was pitched as the “hard science” alternative to the looser, Golden Age-inspired SF of Traveller. 2300AD's other supplements focused on Earthly politics, interstellar cartography, and the starships, among other more "grounded" topics. For all its detail, however, the line lacked a unifying extraterrestrial element, something distinctive that would shape humanity’s place in the larger galaxy. The Kafer Sourcebook was the first supplement to supply that missing anchor. It thus introduced not merely an opponent but an entire framework for understanding alien intelligence within the setting.

At a glance, the superficially insectoid Kafers fill the recognizable role of an expansionist, technologically capable adversary, the kind of civilization that might form the backbone of a future interstellar war. But the Sourcebook's treatment of the species elevates them above cliché. Their defining trait is an evolutionary system in which intelligence surges only under stress, which feels both biologically plausible and conceptually daring. In their calm state, Kafers possess little more than animal cunning. Faced with fear, danger, or uncertainty, their mental capacities accelerate rapidly, granting them the clarity and ingenuity needed to confront threats. The result is a species whose history, culture, and institutions have arisen to support continual conflict, since it's only under such stress that the Kafers' intelligence continues to increase.

This evolutionary need for conflict becomes the core organizing principle for the book. Keith uses it to explain Kafer rituals of testing and challenge, their competitive clan structure, their tendency toward authoritarian politics, and the peculiar way they approach science and technology. The chapters on physiology and psychology are particularly strong, dense with speculative xenobiology that is nevertheless readable, even compelling. The cultural chapters, meanwhile, succeed in painting the Kafers not as a hive of faceless antagonists but as a coherent civilization with internal debates, eccentricities, and historical traumas. One comes away with the sense of a genuinely alien species whose motives can be understood but never comfortably predicted.

For all its strengths, however, the Kafer Sourcebook also highlights the central challenge of the species it so creatively presents. The Kafers are genuinely difficult to use in a typical 2300AD campaign. Their hostility isn’t ideological, political, or territorial in any human sense; it is biological. Once threatened, they are almost compelled to escalate conflict, their intelligence and aggression rising in tandem. This leaves little room for negotiation, espionage, manipulation, or the many shades of diplomacy that fuel most science fiction RPG adventures. A referee who wishes to portray the Kafers accurately must accept that they are not suited to casual interaction. They are best deployed as a looming existential threat or as the fulcrum of a military campaign, rather than as participants in the varied social and exploratory scenarios that populate the rest of the setting.

That is what makes the Kafer Sourcebook and, by extension, 2300AD’s use of the Kafers so frustrating. The supplement is filled with wonderfully imaginative speculation that makes these aliens excellent antagonists, yet it offers little sense of how they might function in any capacity other than that of an implacable foe. Keith’s efforts to avoid making the Kafers one-dimensional “bad guys” by rooting their behavior in evolutionary psychology paradoxically reinforces that very one-dimensionality. A species that becomes intelligent only when threatened cannot be negotiated with, reasoned with, or engaged meaningfully outside the context of conflict. In a game line otherwise rich in politics, exploration, and cultural interplay, the Kafers remain locked into a very narrow role. The result is an alien species that is brilliantly conceived on the page but difficult to integrate into the broader possibilities the 2300AD setting seems to contain.

Mind you, this is my eternal complaint about 2300AD. It’s an extraordinarily imaginative and beautifully presented setting, one that feels right in all the ways hard science fiction should, yet it somehow ends up feeling strangely dull. Unlike Traveller, I could never quite get a handle on what GDW expected players to do with the game. Its “realism,” whether technological, cultural, or political, always seemed to work against the very things that make adventure possible. Instead of opening doors, its grounded assumptions often closed them, leaving referees to do the heavy lifting of carving out reasons for danger, mystery, or wonder.

I think hat’s the tragedy of 2300AD: a setting bursting with potential, yet one that never quite shows you how to tap into it. It’s a toolbox full of fascinating parts, but without a clear sense of what you’re meant to build.
