I've always been interested in the Spyrers from Necromunda - they are such a unique group with a fantastic background and reason for being. The idea of snobby rich kids donning powered armour bristling with advanced weapons, then descending into the Underhive to hunt the dregs of their society in order to prove their worth is very appealing - at least as part of the grim, dark future of the Warhammer 40,000 Universe.
I decided that it is likely that nobility from numerous hive-worlds might take up such an idea and send their own heirs into the crucible of battle that exists in the lowest levels of most hive cities. That being said, in a galaxy torn apart by war it is not unlikely that these hunting parties might sometimes find themselves smack dab in the middle of a planetary invasion, a mutant uprising, a political coup or some other conflict - forcing them to fight their way to safety, or to battle for their lives and the freedom of their hive or world.
I figured it was also possible that some of these nobles might get bored, secure passage on a merchant ship and seek out new challenges to test their skills and the limits of their equipment.
I also thought it might be fun to throw the little brats into battle with the most dangerous foes available and see how they fare...
All of this is why I have created the Spyrer Hunting Party army list, presented here in .pdf form for your enjoyment, and especially for your comments and constructive criticism. I have tried to stay true to the nature of each Spyrer, though a few concessions had to be made to make them competetive in the larger Warhammer 40,000 Universe. I also created a list of "Helper Drones" available to the Spyrers (based initially on the "defense systems" the Spyrers have access to in Necromunds, but much expanded), which should help bulk out the numbers a bit to prevent them getting slaughtered too quickly.
Keep in mind that this list is written with games of roughly 500-1000 points in mind. Anything larger would probably not work out so well.
So - what do people think?
