Call of Duty: Modern Warfare 3 — About this game
Defiance follows its own military story during an attack on the United States. Infantry combat alternates with vehicle assignments, including a tank, so the objective and controls change between sections. The touch interface handles weapon changes and usable objects while movement and aiming can use the selected stylus or button scheme. Follow the squad's instructions and use cover before concentrating on distant targets. Clearing an enemy group is only useful if you also reach the current objective; watch the mission marker before searching for the next fight.
