Your mission, should you choose to accept it, is to do battle with the undead.

The galactic supply of "Material 82" is regularly mined from a distant, previously life-supporting moon named "Kal-Briden". No other known supplies of these crystals has been found, nor can they be fabricated. They're greatly valuable in their purpose of laser refraction for interstellar vehicles. Yet, the unthinkable has occurred! The remains of the once living beings of the planet have reanimated and are out on a violent rampage through the mine. You are the mining installation's retrieval units; the robot dogs. Your job is the retrieve every piece of "Material 82" you can find from the mines and return to the surface in one piece. Be warned though, that the skeletons will be chasing you relentlessly.
