Mozilla Video Shows Unreal Engine Running on Firefox

March 13, 2014 by Stephen Daly

Check out Soul and Swing Ninja demos running directly through a browser.

Firefox maker the Mozilla Foundation and Epic Games have released footage of the Unreal Engine 4 running at "near-native" speeds on the web browser. 

No plugins are needed for the technology which is shown running Epic's Soul and Swing Ninja demos in the video below. 

Mozilla chief technology officer Brendan Eich commented: 

"This technology has reached a point where games that the user can jump into via a web link are now almost indistinguishable from ones they might have had to wait to download and install.

"Using Emscripten to cross-compile C and C++ into asm.js, developers can run their games at near-native speeds, so they can approach the Web as they would any other platform."

Epic's founder and CEO Tim Sweeney added that the studio was "blown away" by Mozilla's technology saying they had quickly agreed to work with the Foundation to bring Unreal Engine 4 to Firefox. 

Mozilla announced its partnership with Epic in March, 2013 when it was announced that more than one million lines of Unreal Engine code would be transferred to the Firefox application.
