Some questions on this engine!!!

I’m thinking of making a moba game out of the udk moba kit here’s some questions:

  1. Can I release my moba as non-commercial beta first before paying up?
  2. After I get some donations or crowd funding for this one, how do I pay up? (I don’t own a credit card)
  3. Is there a permanent one-time payment for this engine?(it’s ok for me not to get some upgrades)

If you have questions about UDK please use the UDK forums:

As for licensing–with UDK you don’t have to pay anything until it’s commercial and you’re making money. There is no one-time payment for a license for either UDK or UE4, both have a royalty system besides a license cost.
