Call of Duty: Warzone

Since its first release in 2003, the Call of Duty has rapidly become a staple of historical and hypothetical first-person shooting. Whether sending players into the trenches of World War II or out to distant space stations, the series has retained one constant, and that's the thrill of competitive multiplayer. With Call of Duty boasting its own esports market, players vie for opportunities to join the most notable leagues and square off against skilled players. But to get to that point, they must improve their skills and prove their abilities behind the controller.
