A single-player campaign is a mode in video games where one player engages in a story-driven experience, often completing missions or objectives. This format allows players to immerse themselves in the game’s narrative, exploring the game world at their own pace. Typically, single-player campaigns feature a series of levels or chapters, each with unique challenges and characters. Players often control a main character, such as a hero or anti-hero, and may encounter various NPCs (non-playable characters) that contribute to the storyline. Popular examples include campaigns in games like The Witcher and Call of Duty.
