Call of Duty: Modern Warfare 2 has three different game modes: Campaign, Spec Ops, and Multiplayer. Campaign is a single-player mode where the player completes eighteen levels connected by an overarching plot.

For some it's the original Modern Warfare, whereas others may hail Warzone as the best advancement the series has seen yet. The original Call of Duty: Modern Warfare 2 completed a terrific campaign, and its single-player mode was remastered in 2024 to remind fans why it was so beloved.
