City Defense is a real-time strategy tower defense game that blends tactical placement with fast action. Your goal is to protect the city from successive enemy waves by deploying troops, building obstacles, and upgrading defenses. Each level introduces new enemy types and patterns, so you must adapt your plan as the battle unfolds.
Gameplay centers on resource management and positioning. Earn resources by defeating enemies and completing waves. Use those resources to place units such as infantry, gunners, and heavy units, and to deploy obstacles like barricades, mines, and turrets. Upgrades improve attack power, range, health, and special abilities. The game uses clear 3D visuals and a dynamic camera so you can zoom and pan to watch the battlefield and fine tune placements.
Challenges increase with each wave and include faster enemies, flying units, and armored bosses that require focused strategy. City Defense rewards smart planning: mixing unit types, placing obstacles to funnel enemies, and timing upgrades will keep your city standing. Sessions are suitable for short play or longer strategic runs, offering replayability through varied maps and escalating difficulty.
