Once a year or so someone starts a "Most Underrated WADs" thread on Doomworld and it seems like Donald Howard's Kill! Zone (and its sequel, KILLZON2) are perennial favorites. Don's fanciful publishing house was Heuristic Software, though whether he had anything to do with the then defunct chess game company is beyond me. A reading of the now archived Team TNT roster reveals that he is also the same Don Howard who contributed three levels to Daedalus: Alien Defense. His debut, Vile-Lab, is apparently lost to the sands of time. KZ#1 is a seven-map episode for Doom II and was published in 1996. The author did not bother attempting to establish any semblance of a narrative but if it bears any relation to the tongue-in-cheek follow-up then each of the maps represents a separate bastion of Hellspawn rather than a single adventure with multiple stages.
