About City Defense

City Defense is a real-time battlefield game built around placing troops and obstacles where they can protect the city. Enemies arrive in waves, so your decisions must combine immediate defense with a longer view of how your available forces can handle the attack.

The strategic interest comes from choosing when to deploy units, where to add barriers, and which elements deserve an upgrade. It is not only about stopping the current wave: thoughtful placement and improvements help you create a defense that can keep eliminating attackers as the battle continues.

Tips & Tricks

1Place troops with the approaching enemy route in mind so their positions serve the city rather than leaving gaps.
2Use obstacles to shape the attack instead of placing every defensive element without a plan.
3Choose upgrades that address the pressure your current wave is creating, keeping your strongest response focused on the immediate threat.
