Whether you're building a game or developing an internal application for your business, we have a commercial UDK license to fit your needs. If you're not sure which license is right for your UDK project, please check out the UDK frequently asked questions.
Frequently Asked Questions
- Is UDK really for me to use?
Sure, you can download UDK, create your project and distribute it completely free of cost.
- Can universities, high schools, faculty and students use UDK for free?
Educational institutions can use UDK under our "free for educational and non-commercial use" policy, even though they're charging tuition. No commercial license is required for faculty or students.
If a student, for example, decides he wants to sell a game he made as a school or hobby project he is welcome to do that as well. He would need to purchase our $99 license and then pay us royalties of 25% of his earnings after the first $50,000 he makes.
Note: We highly encourage all students and academic organizations to consider Unreal Engine 4!
- If I or my company makes more than one UDK based game or commercial app. do I need a new commercial license for each product?
No. You or your company will only need one commercial license to cover all games and commercial applications developed with UDK.
- Can Kickstarter, IndieGogo or other crowdfunding programs be used to fund games made with UDK? Is a license required?
Using crowdfunding to help get your UDK game is perfectly acceptable. We do require developers to execute the $99 commercial UDK license as soon as the game becomes a commercial product, whether through direct sale, pre-orders, or a promised "backer reward." All money received for game copies sold whether through direct sale, pre-orders, or "backer reward" are considered to be part of revenue, and are thus subject to the standard UDK royalty at the market value of the standalone game.
Funding earned through donations, non-game backer rewards (e.g., thank you cards, hats, t-shirts), and "fund my life" campaigns, are not subject to UDK royalties. For "backer rewards" that combine merchandise plus a game, only the market value of the game is attributed to total revenue. For example, if you offer a $100 pledge that includes swag and one copy of your $10 game, you only count $10 toward UDK revenue. Any pre-sales of the game are subject to the standard UDK royalty.
- Does selling individual assets, content packs and starter kits require a commercial UDK license?
No. You do not need a commercial UDK license nor will the assets, content packs or starter kits be subject to the standard UDK royalty.
Scenario 1 - An individual creates a weapon pack consisting of meshes, textures, materials, particle effects and UnrealScript files; everything needed to drop the weapons into UDK for use in developing a game. The individual decides to sell the weapon pack through a content marketplace and earns US$75,000 (after any fees imposed by the marketplace) over a period of several years. No commercial UDK license or royalty is required and the individual keeps the entire US$75,000.
Scenario 2 - A team is creating a real-time strategy game. During development, they decide to sell the framework of the game as a "starter kit" that includes a collection of UnrealScript files and some simple stand-in art assets. The team is not required to purchase a commercial UDK license prior to selling the starter kit; however, the team would be required to purchase a royalty-bearing commercial UDK license prior to selling the full game they are developing. They charge US$150 per asset pack and sell 350 starter kits, earning a total of US$52,500. No royalty payment is required and the team keeps the US$52,500.
Scenario 3 - A technical artist creates freelance art assets (materials, particle effects, etc.) for several different teams all working on games using UDK, which are later sold commercially. The artist is paid a total of US$62,500 for their work. The artist is not required to purchase a commercial UDK license or pay royalties and keeps the whole US$62,500. The teams selling the games using the assets created by the artist are required to purchase royalty-bearing commercial UDK licenses and pay royalties on their revenue over US$50,000.
- How much knowledge is required for someone to make a project with UDK?
If you are using Unreal Engine 3 for the first time a good place to start is the Unreal Developer Network. You can visit UDK's home here: http://udn.epicgames.com/Three/DevelopmentKitHome.html
And the Getting Started with UDK portal is here: http://udn.epicgames.com/Three/DevelopmentKitGettingStarted.html
There are also "Mastering Unreal Technology" books, authored by 3D Buzz and published by Sams.
- "Mastering Unreal Technology, Volume I: Introduction to Level Design with Unreal Engine 3" http://www.informit.com/store/product.aspx?isbn=0672329913
- "Mastering Unreal Technology, Volume II: Advanced Level Design Concepts with Unreal Engine 3" http://www.informit.com/store/product.aspx?isbn=9780672329920
UDK is aimed at anyone who wants to work with Unreal Engine 3.
- How is developing UDK different from making mods?
What makes UDK different is that it can be used by everyone. You don't have to own a copy of "Unreal Tournament 3" to get access to the engine tools, plus we are continually releasing free UDK updates.
In addition, all UDK releases are standalone products, meaning anyone can release a totally free game that requires no additional software.
- Can I release a UDK game as open source?
The rights to develop and release a game for free are contained in the end-user license agreement (EULA). The EULA is also the license that governs the release of your game as it's built on UDK. You can't release your UDK project under terms other than the UDK EULA (like GPL, LGPL, open source, etc.). You don't have the right to encumber the UDK with terms that we have not already granted to you.
- Can I use UDK to release a game that is free?
Yes. If the game is absolutely free to play and there is no commercial aspect to it then you're welcome to do so under the End User License Agreement. But some free games still require a license. If your game is free but is used to advertise a product or service you need a license for that. If your game is free to download and play but you sell content, services or products within your game that also requires a commercial license. If you're uncertain about whether you require a commercial license or not please email the particulars about your situation to [email protected] and we'll be happy to answer you.
- How does this differ from an Unreal Engine 3 license?
The primary difference is that UDK does not include Unreal Engine 3 C++ source code access. UDK ships with all the UnrealScript code and Unreal Engine tool integrations as the commercial version of Unreal Engine 3, offering the same features the pros use.
The tools and technology are the same however a “full” license includes the underlying C++ source code to the engine and tools, which allows licensees to make virtually any change they want and potentially ship their game on consoles provided they’re licensed by the console manufacturer.
Both UDK users and traditional Unreal Engine 3 commercial licensees have access to all UnrealScript source code. UnrealScript is comparable to a programming language like Java in terms of features and performance (byte-compiled), with features designed to simplify game development, e.g., state scoping of functions, automatic serialization, simple system for defining networking replication of properties and remote functions, etc.
There are tons of great materials and support avenues for UDK users, including the “Mastering Unreal Technology” books, hundreds of pages of support items on our Unreal Developer Network (http://udn.epicgames.com), community forums (http://www.udk.com/forums), and hundreds of hours of free video tutorials from 3DBuzz and many other great developers.
Full UE3 licensees also get direct support from Epic’s engineers.
- Can you explain the UDK commercial license terms?
The UDK is FREE for educational use. Feel free to use it in your school’s curriculum. Educational institutions can use the UDK for free even though they’re charging tuition. No additional license is required for faculty or students. Your students are encouraged to use UDK inside or outside of school to learn game development.
The UDK is also FREE for non-commercial use. Feel free to use the UDK to make any application (game or othe rwise) for free distribution. No additional license (beyond the EULA) is required. Just go for it.
If you use UDK in your business, sell a game or application created using UDK, sell services or training and in connection with that business, distribute an application you’ve created using UDK, or use UDK in any way to generate revenue, directly or indirectly, in addition to your agreeing to the UDK EULA, you are required to sign a UDK Commercial Use License Agreement.
A summary of the current terms of this license are as follows (note that the below terms are only a summary – the actual terms appear in the UDK Amendment):
If you are using UDK internally within your business and the application created using UDK is not distributed to a third party (i.e., someone who is not your employee or subcontractor), you are required to pay Epic an annual license fee of US$2,500 per installed UDK developer seat per year. This license fee only applies to UDK seats used for development; no license fee is required for hardware where only the resulting applications are installed.
If you create a games or commercial applications using UDK for sale or distribution to an end-user or client, or if you are providing services in connection with a UDK based game or application, the per-seat option does not apply. Instead the license terms for this arrangement are US$99 up-front, and a 0% royalty on you or your company’s first US$50,000 in UDK related revenue from all your UDK based games or commercial applications, and a 25% royalty on UDK related revenue from all your UDK based games or commercial applications above US$50,000. UDK related revenue includes, but is not limited to, monies earned from: sales, services, training, advertisements, sponsorships, endorsements, memberships, subscription fees, in-game transactions, rentals and pay-to-play. You or your company will only need one commercial license to cover all the UDK based games or commercial applications you develop.
Here are some examples:
-
A warehouse company uses UDK to create an application for employee safety training. They develop it on one computer and then install the resulting application on two computers for their internal employees to use. They require a single UDK development seat license for a total cost of US$2,500 per year, for as long as they use UDK to develop and/or maintain the application.
-
A team creates a game with UDK that they intend to sell. After six months of development, they release the game through digital distribution and they earn US$60,000 in the first calendar quarter after release. Their use of UDK during development requires no fee. At some point prior to the UDK Applications’srelease they would to secure a royalty-bearing commercial UDK license with its US$99 license fee. After earning US$60,000, they would be required to pay Epic US$2,500 (US$0 on the first US$50,000 in revenue, and US$2,500 on the next US$10,000 in revenue). On subsequent revenue, they are required to pay the 25% royalty.
-
An architecture firm uses UDK to create a live walk-through presentation for their customers. They charge their customers a fee of US$500 for each walk-through. Before they begin to charge customers for the walk-through, they would pay Epic US$99 for a royalty-bearing commercial UDK license. They sell walk-through presentations to 100 customers in the first quarter, bringing in US$50,000 in revenue. No royalty payment would be required to Epic for that first US$50,000. In the second quarter, they sell another 100 walk-through presentations, bringing in another US$50,000 in revenue. They are required to pay US$12,500 to Epic. On subsequent revenue, they are required to pay the 25% royalty.
The UDK Commercial Use License may be executed by an individual or a corporate entity. If an unincorporated team wishes to license UDK, we recommend setting up a simple corporation or partnership for the team before contacting us for a license. If that is not feasible, please designate a single individual to contact us who will be responsible for executing the license and fulfilling the terms.
A note to developers under the age of consent (minors): Please have your parent or guardian contact us for a UDK Commercial Use License, as we cannot enter into a license agreement with a minor.
If you have any questions about licensing UDK or require custom license terms, source code licenses, or use on consoles please email [email protected] for more information.

You further agree that Epic shall be allowed to apply for injunctive remedies (or any equivalent legal relief) in any jurisdiction. For the avoidance of doubt, this Agreement shall be construed and enforced without regard to the United Nations Convention on the International Sale of Goods, which shall not apply to this Agreement.
13. Disclaimer of Warranty. The UDK is licensed “as is.” You bear the risk of using it. Neither Epic nor its suppliers give any express or statutory representations, warranties, guarantees or conditions. Epic and its suppliers also exclude all implied warranties, including any warranty of merchantability, title, durability, fitness for a particular purpose and non-infringement. Nothing in this Agreement shall affect those statutory rights which You are always entitled to as a consumer and that You cannot contractually agree to alter or waive.

The limitations and exclusions of liability do not apply if and to the extent (a) You sustain damages which were caused by gross negligence or willful misconduct of Epic, or (b) Epic violates Your life, body, or well-being.
15. U.S. Government End Users. The UDK and related documentation are “Commercial Items”, as that term is defined at 48 C.F.R. §2.101, consisting of “Commercial Computer Software” and “Commercial Computer Software Documentation”, as such terms are used in 48 C.F.R. §12.212 or 48 C.F.R. §227.7202, as applicable. Consistent with 48 C.F.R. §12.212 or 48 C.F.R. §227.7202-1 through 227.7202-4, as applicable, the Commercial Computer Software and Commercial Computer Software Documentation are being licensed to U.S. Government end users (a) only as Commercial Items and (b) with only those rights as are granted to all other end users pursuant to the terms and conditions herein. Unpublished-rights reserved under the copyright laws of the United States.
16. No Waiver. Any act by Epic to exercise, or failure or delay in exercise of, any of its rights under this Agreement, at law, or in equity shall not be deemed a waiver of those or any other rights or remedies available in contract, at law or in equity.
17. No Support. Neither Epic nor its suppliers has any obligation to provide support services for the UDK or any portion thereof.
18. No Assignment. You shall not, without the prior written consent of Epic, assign, transfer, charge, sub-contract or deal in any other manner with all or any of its rights or obligations under this Agreement. Epic may at any time assign, transfer, charge, sub-contract or deal in any other manner with all or any of its rights or obligations under this Agreement.
19. Legal Effect. This Agreement describes certain legal rights. You may have other rights under the laws of Your jurisdiction. This Agreement does not change Your rights under the laws of Your jurisdiction if the laws of Your jurisdiction do not permit it to do so. Limitations and exclusions of warranties and remedies in this Agreement may not apply to You because Your jurisdiction may not allow them in Your particular circumstance. In the event that certain provisions of this Agreement are not enforceable in Your jurisdiction, such provisions shall be enforceable to the further extent possible under applicable law.
