A little while back we revealed that Epic Games was working on an HTML5 version of Unreal Engine 3 that could be used on most modern browsers. Today, Epic Games has released Epic Citadel and through the use of HTML5, WebGL, and JavaScript, you can now experience Unreal Engine 3 through Firefox.
If you have a capable browser, be sure to check out the Epic Citadel browser demo right now. Don't forget that the same demo is also available for Android and iOS devices.
“Epic Citadel” is built using standards-based technologies like HTML5, WebGL and JavaScript, and should work in any standards-based browser implementing those features. For optimal performance, Epic recommends loading “Epic Citadel” at http://www.unrealengine.com/html5 using Firefox Nightly version 23 or above, which includes optimizations for asm.js, a highly-optimizable subset of JavaScript pioneered by Mozilla, whose performance can rival native code.
