A second boxed set called "Knight Hawks" followed shortly. It provided rules for using starships in the setting and also a set of wargame rules for fighting space battles between the UPF and Sathar. Included were counters for starships, two-ten sided dice, a large folding map with open space on one side and on the other a space station and starship (for use with the included adventure), and the adventure SFKH-0: "Warriors of White Light". This set was designed by Douglas Niles (who also designed the D&D wargame "Battlesystem", released two years later).
