Sort of a reverse Expedition to the Barrier Peaks, then… I’m still unclear just what kind of mash-up this was. A straight D&D game where the characters are shocked to find out they actually live in a high-tech world and that they’re secretly mutants, pyskers and chaos heretics (not wizards and whatnot), or more of a blending, using the mechanics (and some classes) from D&D fully within the context of a WH40K setting, possibly with things like guns bodged in. I’m assuming the latter, but the first has a perverse appeal too (I have a not entirely dissimilar game world written out).
I’m only aware of the various Fantasy Flight RPG books (of which there seem to be an excessive number). It’s kind of surprising, as the first edition Warhammer 40k - and that “Rogue Trader” subtitle - was very much set up to be RPG friendly, at least in terms of the focus. (Not so much emphasis on Space Marines, etc.) I always expected a 40K version of the Warhammer Fantasy RPG, but it never came.
