So I was watching John Carpenter's Ghosts of Mars, and it struck me for the first time how "40k-ish" it is in atmosphere and such. Seems like the story has potential to be converted into at least a short-ish, one-off type module. Gonna throw a couple of ideas out here, and if anyone has any suggestions/improvements/additions I'd love to hear them!
1. Party choices . Have two different thoughts here. Either a standard party of Adepts, as this seems like the kind of thing an Inquisitor might send his people to do, or else have them all roll Arbiters and maybe one or two scum.
2. Desolation Williams . Since there's a fair amount of gunplay, thinking a hardened Metallican Gunslinger. Could use him as dramatically appropriate if encounters are too tough, etc. Would likely change his name, so it wouldn't be instantly obvious what the module is to those who may have seen the film.
3. Bad guys . Thinking either Khorne cultists (archaeologists unlock a door that was holding back daemons or some such) or Dark Eldar influence of some sort. Not 100% sold on Khorne though (as that is more violence for a deity's sake). Dark Eldar would seem to fit in with some of the speed and horror tactics that the enemies use in the film, although I'm not sure about how that would spread. Maybe some Dark Eldar cult was locked away and their ghosts are what is possessing folk.
Those are my initial thoughts, at any rate, for what they're worth.
