Unity City Builder

Everything you need to create a city-building sim game like Clash of Clans. Players can build their own villages with buildings you create. Design buildings using your favorite 3D modeler like Blender, Maya, or 2D graphics programs like Adobe Illustrator, Photoshop, or even GIMP.

Import animated sprites, set wait timers, and build your city builder prototype in days instead of weeks.

The game engine kit supports basic assets or animated sprites. Demos and source code included. For advanced developers, we have private documentation for how to convert from 2D to a 3D Unity City Builder.

Build your own mobile strategy games with

Includes 11 building types you can use in your game

(add your own 3D or 2D buildings too!)

Plus, monetize extra builders to earn revenue from your players!

Like popular city building strategy games, players get one free builder to take down trees, create buildings, or make defenses. Each of these actions takes time to complete.

Extra builders can be purchased in the store, but they cost a rare gem currency you can charge game players real money for with in-app-purchases (IAP).

Monetize your game and allow paying players to build more than one thing at a time in your game. All this timesaving code is structured and ready-to-go for you with more great features..

Frequently Asked Questions

What do I need to run the Ultimate Kit?

Unity Hub (or 2019.4.2f1 (LTS))

NO LONGER NEEDED- 2D Toolkit v2+

What about Unity’s 2D support?

Yes, Unity comes with 2D and UI support but it’s not enough to build the entire kit. You still need the further advanced assets that we include at NO additional cost to you!

Can I upgrade my kit?

Yes. You can upgrade from Starter Kit to the Ultimate Strategy Game Kit for $300. Also, if you have a prior version of the Complete Kit or the Pro Kit, you can upgrade for a reduce price of $50). Upgrades are available in the download center for customers.

Can we change everything in the kit?

Yes. You’ll receive the complete Unity3D source code after buying. Add/remove your own features, scripts, or characters. Nothing is locked in DLLs and you can access all the code needed to create a functional prototype.

Does this game kit support attack and defense like Clash of Clans?

The Ultimate Strategy Kit includes attack and defense, plus server side scripts necessary for managing player villages just like top-ranking games like CoC, GoW and other RTS mobile games. It’s more like CoC is, not a full-on MMORPG or MMO.

What devices does the kit run on?

The kit runs on all devices – Apple, PC/Mac, web applet and Android devices. Plus, the game is optimized for Unity 2d mobile with the touch controls. Export straight to XCode for iOS 8 games using this clash of clans game engine.

How do I setup In-App Purchases?

The included In-App Billing script is setup so all you have to do is connect the purchase variable to your billing system, for example Store, a free Unity IAP asset you can download from the Unity Asset Store. See the In-App Billing documentation

I’m getting a UI Label Error?

When trying to build the game in Unity3D and getting those UILabel errors, we recommend that you double check if you have The Ultimate Edition. It is needed to run the starter kit properly.

So everything is setup and ready to go?

Yes, everything is setup already. (We recommend build and running on your mobile device with Apple XCode or the Android SDK)

How can I get the latest version?

Click the download link at the top of this page and login with your purchase details, downloads, tutorials, and special offers only available for City Building Kit Unity3D customers.

Why chose Unity 3D over other engines?

Because Unity 3D has over 2 million developers all over the world and games that reach over 600 million gamers. Unity 3D also offers a huge collection of expansion assets and free game tutorials perfect for a clash of clans game engine.

Purchased By Game Developers Worldwide

Some of the world’s biggest asian game brands worked with the City Building Kit
— along with famous US game developers like Levelord, entrepreneurs, and hobbyists.

I’ve played with others, but this one is the best! It’s definitely more than a mere “start-up” kit as it already has 90% of a game foundation in the kit. It is easy-to-use and intuitively designed. I highly recommend this kit for anyone considering making a city building game!

Levelord Games

Update: In less than a day, I am comfortable with most of the pipelines to add my own buildings and characters (graphics and behaviors/parameters), and I have modified menus, buttons and various GUI interfaces. This is a great kit!

Levelord Games

If you are looking to make a city building game, this is the kit for you. Everything works [straight] out of the box, and I have spent a good amount of time playing around with the default buildings/units. Awesome kit, I can’t suggest this enough!

Ronime Studios

Wow, thanks a lot! Your package saved us a lot of time prototyping! Keep the good work!

Fantix, Flow Forge

What can I say? .. wow, just wow! 🙂 you guys making things above expectations. I haven’t fully tested yet Unity Project and all new features, but what I’ve seen from Video and new description simply awesome. I did however tested APK-file on my Android tablet and I can confirm: the feelings of game touch improved significantly. Movements / zooming with On-touch on Android device is really-really pleasant.

We have build a city builder game from the ground up before in pure Javascript. This was a very time consuming effort, and since we [were] looking now for something similar using Unity this city builder kit was the answer. We have tried it out and where impressed by the quality and ease to use! These guys really did an outstanding job!

Martijn Gun Van Der

Awesome Building Complete Kit!
What can I say? .. wow, just wow! 🙂 you guys making things above expectations. I haven’t fully tested yet Unity Project and all new features, but what I’ve seen from Video and new description simply awesome.

Update: Let me start by saying that I’m a big fan of ‘Clash of clans’ game, and if you are looking for an asset that will help you to develop something similar, then the City Building Kit is exactly what you need. Seriously, if you think of complexity of the games like Clash, how much must be done before you own creation turns into a game, then this Kit is a life-saver!

As Unity designer and programmer I sure do know how many hours one has to spent to develop and release a dissent game. That is why this City Building Kit saved me tons of hours in the beginning, so I could concentrate on my own game idea and polishing of game elements. You need to have two other assets in order to make it work, but who of us devoted developers doesn’t have already NGUI or 2DToolkit now-days? )

I bought a Starter Kit about a year ago and then upgraded to Pro version, and I do not regret it.

Alex Shmit


Very nice kit!

Andre, Info Team


Very Good Kit, easy to expand and easy to use.



Beautiful Updating …

Daniele DalCin

Bigger and more documentation is always good. I have been able to read through gigantic manuals and it helps my learning and it is how I have become incredibly profient with the 3D pieces of unity. The 2D stuff is new for me so the more the better. I’m always for developers reaching out and I will continue to update my rating as things improve and I will reach out regardless with some specific issues I have that are more geared towards support than a written review. Thanks.

Felix George

This is a nice kit really well coded and documented.

Good Kit

Great Kit!
I bought this kit over a year ago and even though i have yet to publish a game with it, it is by far my favorite kit in the asset store. Its packed with great systems and is more than a starting point for anyone looking to make a game like this. Thanks for the amazing asset & I greatly look forward to the new updates!
