Each Call of Duty season comes with massive content patches. These patches are essential to keep the existing player base engaged in their favorite game, while also attracting many returning or new players to the franchise.
Activision's Call of Duty League (Quick Cast 9/25)
The seasonal system took its final form with the release of Modern Warfare and Warzone. It was unclear what would happen to the seasonal count with the release of new CoD games, but Black Ops Cold War answered that question by resetting the seasonal count to one.
That trend continued with Vanguard and Modern Warfare 2 , and now Modern Warfare 3 looks set to continue that trend even further with subsequent Call of Duty releases over the next few years. Activision has found a formula that works when it comes to making money and pumping out content.
The first season of MW3 kicked off less than a month after release and added a ton of new content to the game, including new maps, weapons, game modes, operators, and MW3’s Warzone integration.
