The city has a life of its own. Your task is to protect it. PPO: Defend Your City is a strategy game about defending a city from aerial threats. Deploy air defense crews, choose positions and targets, keep ammunition flowing and rebuild damaged neighborhoods. Every decision shapes how your city faces the next attack. BUILD YOUR DEFENSES Machine-gun crews, missile systems and heavy systems serve different roles. Consider their range, cover vulnerable approaches and upgrade your equipment as your defenses grow. MANAGE YOUR CITY Balance your budget between defense, supplies and repairs. While your crews repel attacks, traffic moves through the streets, firefighters tackle blazes and emergency services help residents. SET YOUR OWN PACE Pause time to assess the situation and plan your next move. Speed through quiet moments and return to normal speed when the battle begins. EVERY GAME, A NEW CITY Procedural layouts, different city sizes, a day-and-night cycle and changing weather reshape the conditions for defense. Play a standalone operation or start a campaign. AT HOME ON YOUR SCREEN Use touch controls on iPhone and iPad, or a mouse and trackpad on Mac. Choose a light, dark or automatic interface theme. Previously playable in your browser, PPO is now available on Apple devices too. No separate game account is required.
