In City Defense Z, manage your base by day and fend off zombies at night. With roguelite upgrades, see how long you can survive as you build smarter with each attempt.
About this game
What you do during the day pays off at night: gather resources, place buildings, merge structures, trade resources, choose your NPCs wisely, send them on expeditions, deploy soldiers, merge units, and position your troops strategically.
Factory Buildings: Produce the main resource you need to build and upgrade your base.
Ammunition Buildings: Create ammo for soldiers, defenses, and special attacks.
Barracks Buildings: Train new soldiers every cycle.
Laboratory Buildings: Generate research points for permanent upgrades that carry over between runs.
House Buildings: Increase population limit, allowing you to grow your army.
Merge-Based Building System: Soldiers and buildings automatically merge when placed smartly on the grid.
When night falls, don’t give up if your strategy isn’t working. You still have tricks: call in airstrikes and collect boosters to power up the defense units you placed during the day.
Lost a run? It’s time to come back stronger. Spend the research points you’ve earned, pick the permanent upgrades that match your strategy, and try again. Each run, you’ll get better than the last.
Permanent Meta Progression: 13 research trees providing persistent upgrades.
13 Research Trees: Choose upgrade paths trough 150+ meta upgrades that complement your playstyle.
Constant combat, constant adrenaline! As you defend your city, the action never slows down for a second. Build your strategy and stay in control in the heart of the battle.

One Year of City Defense Z | Built With Your Feedback
One Year of City Defense Z | Built With Your Feedback On August 25, 2025, City Defense Z went live. One year later, this is not the game we launched. That is because of you. Your reviews, forum posts, Discord messages, and bug reports shaped the year. We read them all. We still do. What Changed in Year One We started with a 10-day patch challenge, then kept going through roadmaps, major updates, and hotfixes, listening to you guys the whole way. Here is the short version of what your feedback turned into. • New map, new units, new cards, and new traps • Bigger permanent upgrades, a market, and seasons • Faster army control, merging, and building flow • Rebalanced pacing, economy, food, and expeditions • Hand-drawn NPCs, a full UI rewrite, and clearer tutorials • Steam Deck verification, controller support, and performance work • Audio, cinematics, localization, achievements, and hundreds of fixes We Are Still Here We are a small team, and we are still answering every review and every forum post. That has not changed in a year, and it will not change now. If you bounced at launch, the game is in a very different place. If something still feels off, tell us. We are still listening. Thank You, Survivors From Good Mood Games, thank you for one year of defending the city with us. Keep talking. We are still reading.
