Up until now Epic Games has used its Epic Citadel software to show off the Unreal Engine's abilities on mobile devices. The medieval town and elaborate castle is reminiscent of the company's Infinity Blade franchise, featuring rich detail and impressive lighting. An HTML 5 version of that same tech is now available for perusal in your web browser.

The video below shows off the environment, and even features brief gameplay footage of an Unreal Tournament-like game being played free of hiccups.

Epic Games recommends running Epic Citadel in Firefox Nightly for the best performance. After you've installed the free browser click here to check out Epic Citadel.
