Step-by-step explanation:
As of my knowledge cutoff date in 2023, Overwatch has four official game modes. These game modes are: Assault, Escort, Hybrid (a combination of Assault and Escort), and Control. Each mode has unique objectives and strategies, offering a diverse gameplay experience to players.
