Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Fees and releasing games on UDK or UE4

For UDK 1) Is UDK still OK and FREE to use? 2) Can we still release games made using UDK? 3) If I make a game in UDK and want to release it, what are the fees?

For Unreal Engine 4 1) If I pay a subscription fee now, download Unreal Engine 4 and then cancel the subscription for now, do I have to re-subscribe before I can release the game?

UDK: Yep, you can still use and release games with it. https://www.unrealengine.com/products/udk/udk-licensing-resources#commercial

At the bottom of the page you can see the UDK licensing terms.

1 - UDK is ok to use and it is free for non-commercial use.

2 - You can release a game made with UDK with the purchase of a commercial license.

3 - There is a $99 commercial license fee as well as royalties on game sales.


1 - No, you don't have to resubscribe before you can release the game. You do need to notify us of the game's release though.

Hi Canon, thanks so much for the info.

I want to use UDK commercially - that is - to make a game I can publish and sell. What do I have to pay in this case?

OK, I see you've answered this question in number 3.

OK, so there's a $99 license fee for UDK (did not know). For UE4, is there a similar license fee or just the royalties?

The following link addresses commercial terms for UDK:


The UE4 subscription grants you a commercial use license; there isn't a separate commercial use license fee, but as you said, royalties will apply.
