Can 5% royality payment affect, if I publishing FREE games?

Hello, Epic Games!
This question is VERY IMPORTANT.
I heard about 5% royalty, but if I publishing my projects/games, created on Unreal Engine 4, on App Store, Google Play, Steam for FREE (no monetising), can this 5% payment work and I will need to give your company a 5%?
Please, answer me!
(I think if the game is FREE, there is no royalty paying responsiblity)

5% of zero is zero.

Allar is correct. If the game is completely free (no access fee, no in-game transactions, no advertising revenue, etc.), there is no revenue so no royalty is owed.

THHAAAAAAAANNNNKK YOOOU!!!
Now I have just create a Mac and Windows version of game (Steam or GameJolt), and create a smaller version for IOS and Android (App Store or Google Play).

“Black Recon” wil come to LIFE.

I wanted to publish games on Steam, and Russian cities’ maps (and more game materials) on MARKETPLACE for FREE, because I think I’m not ready to trade and earn $MONEY$.
Projects of Lucky Cat Studios (my creative studio) are ABSOLUTELY FREE and created for having fun.
My royalty for projects/movies/games/arts - is a happiness of my fans.
Thank you, Epic Games, for setting free the engine. :)))))))
