Dead or Alive: Code Chronos was the code name given to a cancelled Dead or Alive video game. During a interview with Play Magazine in July, 2006, Tomonobu Itagaki stated that Code Chronos would be a prequel to the Dead or Alive series, and would relay the story of Ayane and Kasumi before the first tournament. The progress of Code Chronos seemed to come to a halt due to Itagaki's dispute with Tecmo.
