How to apply for a UDK commercial license?

Could you please show me how to apply for a UDK commercial license?
I have visited UDK Licensing Resources - Unreal Engine and found nothing relevant.

Thank you.

Do what it suggests under licensing terms and email, see quote:

“If you have any questions about licensing UDK or require custom license terms, source code licenses, or use on consoles please email udk-licensing@epicgames.com for more information.”

Thank you for your help.

Also, just want to add that the royalties for the UDK license are the exact same as for the UE4 license, so the 15% royalty rule no longer applies. You only owe Epic 5%.

At least according to Joe Kreiner. (Not sure if I am at legal liberty to show a screen-cap from the email conversation I had with him when I asked for questions with releasing my game.)
