A Traveller campaign set somewhere on the Imperial Rim. The PCs are members of a platoon of Imperial Marines, stranded on a suddenly-deserted planet, trying to escape the terrible alien invaders who seem to have done away with the entire population, and slowly uncovering a web of secret "black" projects and hidden agendas.

As is now apparent, this campaign includes races and concepts lifted directly (well, tweaked a bit) from the Blizzard RTS game Starcraft. For more (lots more) information about the Zerg, the Protoss, and a game which still rates for me as one of the three best I have ever played, visit the Blizzard site or the SCUM homepage.
