Infinity Ward served as the lead developer for Modern Warfare 2, but Treyarch stepped in and created Ranked Play for multiplayer and Warzone in MW2. Both modes instantly became a hit within the community, but that party is ending soon.
MW2 multiplayer experienced a massive uptick in interest when Ranked Play was finally added in February 2023. The mode provided a perfect platform for Call of Duty League fans to scratch that competitive itch they get from watching matches from home. The devs also provided extra incentive for pro players to dive in, awarding special recognition if a CDL player entered the top 250.
