Last year, Epic released a Flash version of its Epic Citadel tech demo. Now, thanks to WebGL, there's a new flavor of Epic Citadel that can run inside your web browser without plug-ins—and it's ready for public consumption.
Here's what's going on behind the scenes, as explained in the official FAQ:
Now, one of the downsides of standards-based web apps is that they rely heavily on browser support. That's the case with this demo. For best results, Epic says you'll want to grab the latest Firefox nightly. The stable release of Firefox works, but it's slower. As for other browsers, well, the demo crashes in Chrome (Epic says Google is working on a fix), doesn't work in Internet Explorer (that browser lacks WebGL support), and is "currently not compatible" with Opera.
Which leaves just Firefox, pretty much.
It's still early days, of course. Epic says it expects that "most or all browsers" will "eventually" support this demo. Also, as we reported last month, Epic has big plans for standards-based browser gaming based on Unreal Engine 4. Considering Epic's size and influence, I think browser developers may not drag their feet too much.
