Killing Time was originally created for a cult gaming platform called 3DO, then in 1997, Logicware released the Macintosh version. Critics dismissed it as a "Doom clone," but I was impressed by the music, sound effects, gore, and overall mood of Killing Time. I played it off and on for about a year, unable to figure out the conclusion, so I searched online for help and found a whole galaxy of reviews, screenshots, and cheats... but no walkthrough... so I decided to lock myself up for a week and write one.
