The Ko Combine r450 "Shepherd" sets the standard for civilian drone tenders with its unmatched reliability, low cost, and generous internal volume given to crew comfort. A wildly popular combat modification package for the Shepherd has been assembled by various survivalist and pirate groups, the "HK" mod, which consists of specifications to up-armour the ship for combat and supercharge factory-spec systems for greater burst speed and weapon functions. Even modified, the Shepherd is fragile, so as in civilian life it relies on a swarm of 'Borer' utility drones to do its work.
The "Borer" is built on a hardy, maneuverable semi-autonomous drone chasis with shielding suitable for hazardous operations in which high radiation or physical impacts may be expected. Commonly used in mining applications, they also found use in salvage, ordnance disposal, and even fission meltdown clean-up. The HK mod package gives specifications for altering the primary cutting beam's focus and patches the rudimentary AI with crude tactical algorithms pirated from obsolete Domain Colonial Garrison drone software. Appendices of the mod package note to use caution when employing HK-modified drones in non-combat situations.
