After a wildly successful last few months thanks to Fortnite, Epic Games is delivering some substantial new updates to its Unreal game engine which supports a variety of cross-platform titles and experiences. Some features like smoother compatibility on mobile and better support for Switch come directly from the fact that they’ve had to iterate so quickly on building such a massively successful cross-platform title.

“Our engine is as good as it is because we ship games,” Epic Games CTO Kim Libreri told TechCrunch. “How many clicks an artist has to do to be able to change the color of something or adjust the look of something is all highly optimized because the artists scream at us day-in and day-out on the engine team if it’s not efficient.”
