Gameplay modes refer to the different ways players can engage with a game, each offering unique experiences and challenges. Common modes include single-player, where one person plays through the game alone, and multiplayer, which allows multiple players to compete or cooperate, either locally or online. Other modes may include co-op, where players work together to achieve common goals, and competitive, focusing on player versus player challenges. Some games also feature story mode, emphasizing narrative, and sandbox mode, allowing players to explore and create freely without specific objectives.
