Mission-based gameplay is a game design structure where players complete specific tasks or objectives to progress through the game. These missions often have clear goals, such as defeating an enemy, collecting items, or solving puzzles. This format helps guide players and provides a sense of direction and purpose within the game world. In many games, missions are organized into levels or chapters, allowing players to experience a narrative or storyline as they advance. Popular examples of mission-based gameplay can be found in titles like Grand Theft Auto and Call of Duty, where each mission contributes to the overall experience and player engagement.
