Call of Duty adopts the core gameplay dynamics of the first-person shooter genre. The game aims to realistically portray the atmosphere of World War II. Players advance through enemy lines using weapons typical of the era. One of the game’s most distinctive features is the requirement to move alongside AI-controlled squad members rather than operating as a lone operative. This team-based structure immerses the player in the experience of being part of a military unit. Player health is restored by collecting medkits. The game includes fundamental combat mechanics such as taking cover and aiming down sights, and features mission designs that encourage strategic thinking.
