The highly anticipated Season 4 for Modern Warfare 3 and Warzone has made its debut, bringing a host of additional content to both games. From the addition of two 6v6 maps, Paris and Tokyo, to the arrival of Gulag variants and updates to the opening Urzikstan Bunkers, there is plenty for gamers to dive into. One of the most welcome additions, however, is the return of the fan-favorite Kar98k.
