Back in the late 00s a developer called "Atomic Games" was developing a tactical shooter for the Xbox 360, PS3, and PC called "Six Days in Fallujah," based on the historical Second Battle of Fallujah that occurred in November 2004. Konami was originally set to publish it, but in 2009 pulled out of the publishing deal and the game was put on hold. The reason why Konami pulled out of the publishing deal is because the game was causing a lot of controversy among special interest groups who thought the game looked like it'd be disrespectful to the veterans of such a recent event, even though the developers assured it'd be a realistic and accurate portrayal of events rather than a Call of Duty styled "Action movie" like game. Atomic Games went out of business in 2011 and never was able to find another publisher.
Now in 2021 it's been confirmed that a development studio consisting of ex-Bungie staff called "Highwire Games" is taking on the project (with publishing duties being handled by a company called "Victura") and aiming to keep the game's depiction of events as authentic as the original developers wanted (and the trailer seems to indicate they're heavily working with Iraq War veterans to assure it's respectful, unlike what some people tried to claim back in 2009). The game is set for release in 2021 with a PC release on Steam being confirmed and it'll likely come to consoles like PS5 and Xbox Series X as well.
