Ever since season six of Call of Duty: Modern Warfare concluded, Activision and Infinity Ward seemingly put the game on ice. Since that date, there has been no fresh content added to the game, but that all changed recently when Call of Duty: Black Ops Cold War's season two reloaded update went live, as three new maps were brought to the game, including a Call of Duty 4 fan favourite, Killhouse.
The three maps that are Killhouse, Al-Raab Airbase, and Drainage have joined Modern Warfare's map rotation now, with Drainage being added for the Gunfight game mode. There has been no mention about the new maps from Infinity Ward, meaning we can likely assume that this is just a nice addition and that it is probably not going to be a common occurrence in the future, unfortunately.
