Recent developments in the adventure I am running have led me towards thinking of sending some Mandrakes after the group. They've had a run in with the Cabal of Crimson Woe in the past due to Shades on Twilight, which I slotted into my campaign as a diversion for them. The current thought is to have the Mandrakes slip aboard the players ship in the same way as they got onto the Twilight, with what I presume was a warp gate of some kind. I was originally planning on a full-scale Dark Eldar attack, but further thought on it made me consider this to just be daft.
Instead a squad of mandrake will slip aboard the ship in an effort to assassinate the players and the senior crew. This should enable me to ramp up the fear rating a little more, and make it more RP based instead of plodding through lots of combat. The thing is I can't remember much about mandrakes from 40k, apart from their super-sneaky nature. So what sort of equipment should I be looking at, and what kind of weapons etc?
After poking through the Radical's Handbook I quite like the idea of them all wearing Eldar bodygloves with chameleoline coatings. If I go with the bodyglove from the core rules and simply make them best quality, this should make them very hard to detect with the chameleoline coating as well. Weapon wise a brutal mono-knife of some kind and splinter pistol seems the most logical, but I'm considering the garotte from the Radicals Handbook. I think that kit should make them fairly nasty, but hopefully not too nasty. I'm thinking of having them attempt to take care of the players in their sleep, a few will be detected as I have some light sleepers, who will probably be able to deal with the one's sent to take care of them before dealing with the ones attacking the other players. After that, preventing the other mandrakes from murdering key personel onboard the ship seems a good bet, and at this point I'd probably really play with their stealth abilities, having them apear to attack whoever is at the back, phantoms on the players auspexes etc.
Any other ideas would be welcome!
