Six Days in Fallujah (SDiF) é um videogame de tiro em terceira pessoa histórico inédito que foi desenvolvido e deixado inédito pela Atomic Games. Dizem que seria o primeiro jogo a se concentrar diretamente na Guerra do Iraque (que ainda estava em andamento na época). A Konami seria a distribuidora original. The premise of the game was the subject of controversy in 2009, with questions raised as to its appropriateness, especially given the fact that the true events the game is based upon was recent at the time. It was originally to be published by Konami, however, in April 2009, a spokesman informed the Associated Press that Konami was no longer publishing the game due to the controversy surrounding it. The game was originally slated for a 2010 release, but it was cancelled due to controversy; the game was put on hold until 2016 after its original studio, Atomic Games, went bankrupt in 2011. Eventually the game would get picked up again in 2021 by Highwire Games and finally released under the same name by a different team and publisher.

Six Days in Fallujah is the first video game to focus directly on the Iraq War. The game follows a squad of U.S. Marines from 3rd Battalion, 1st Marines (3/1), fighting in the Second Battle of Fallujah over the span of six days in November 2004.
