Mozilla has teamed up with Epic to create a port of the Unreal Engine 3 for use in your Firefox browser without the need for any plugins or installations.

At the Game Developer’s Conference in San Francisco, Mozilla revealed that it has partnered up with Epic to work on a new technology that could allow high end, console quality games in your Firefox browser. This is all possible thanks to OdinMonkey, an optimized version of Javascript which Mozilla has been developing behind the scenes for some time now.

OdinMonkey was described in a Mozilla blog post as being able to “[supercharge] a developer’s gaming code in the browser to enable visually compelling, fast, 3D gaming experiences on the Web.” Epic used the code to port a version of their Unreal Engine 3 to the browser, and after tweaking the engine for a few days, they were able to demo their Epic Citadel game in Firefox. The demo is available for download online, but Epic hasn’t mentioned whether it will commercially release the Unreal Engine for browsers in the future.


Equally exciting is that Mozilla is planning to port the technology to their mobile browsers and Firefox OS, meaning we’ll soon have compelling 3D experiences on the go, in addition to our regular apps. During development, Mozilla has been partnering up with Disney, EA and ZeptoLab to provide some ported games to the browser once a stable build rolls out sometime in June.
