Activision may have unexpectedly fixed the matchmaking for some old Call of Duty games, sparking speculation about the series' future. The Call of Duty franchise goes back to 2003, and as a result, there are several installments that have fallen by the wayside as more have been released, but Activision may have new plans for the classics.Given that Call of Duty has been a series that has annual releases, the Activision FPS has an extensive library of titles. While the latest Call of Duty launch is known for having spawn or balance issues, some of the older ones have become unpopulated due to development resources being allocated elsewhere. However, the inactivity of these old Call of Duty games may become a thing of the past based on some fixes that have been spotted in Call of Duty 4: Modern Warfare, Black Ops, and more.RELATED: Call of Duty Fans Worried New Skin Could Be Roze All Over Again Charlie Intel has shared a viral clip from Call of Duty 4: Modern Warfare, not its remastered counterpart. The video that was presumably recorded recently was captured with the Xbox 360 version of the classic Call of Duty, and it shows the player named akaZekco looking for a game of Team Deathmatch. What would normally result in a lengthy queue that doesn't always end in getting a game is instead replaced by an immediate match on Ambush, and Charlie Intel repeats the process with multiple installments to show how widespread the fix is.[EMBED_TWITTER]https://twitter.com/charlieINTEL/status/1679194512466530305[/EMBED_TWITTER]The Call of Duty clip continues its matchmaking test with the 2009 version of Modern Warfare 2. Just as quickly as the initial lobby was found, the video shows Modern Warfare 2 find a group for a match of free-for-all, with each game mode showing an active community of players. The video then shows that it's just as easy to find games in Call of Duty: Black Ops and Modern Warfare 3 which may suggest that Activision has made a fix to its full lineup of Call of Duty titles. While Charlie Intel has stated that Activision hasn't clarified why the adjustment was made, it hints that the changes could be a result of the recent Microsoft legal victory.Though some of the newer Call of Duty releases like Vanguard and Black Ops: Cold War continue to get a level of server maintenance, older titles like the original Modern Warfare 2 and Black Ops 2 are taken over by hackers. These hackers would often activate zero gravity mode or advance everyone in the lobby's experience, making the multiplayer of these classic Call of Duty titles unplayable which may still persist.MORE: Call of Duty: Warzone Caldera Deserves a Finale Like Verdansk
