WebGL Game Demo – Unreal Engine 3 (Epic Citadel)

WebGL Demo - Unreal Engine 3 (Epic Citadel) - 1

Epic Citadel is a WebGL Game Demo showcasing the amazing graphics of the revamped Unreal Engine 3. Be aware however that this demo is so cutting edge that it has been specifically optimized for Firefox and may only work if you install Firefox Nightly. In order to get Unreal Engine 3 converted into WebGL, the developers over at Mozilla used a combination of asm.js and Emscripten libraries. We’ve seen Emscripten used before in the Unigine Crypt Demo.

Below is a list of graphical features employed by Unreal Engine 3 for WebGL.

  • Amazing visuals. Through the latest advances in Unreal Engine 3 technology, “Epic Citadel” pushes the envelope for modern game visuals on the Web.
  • Realistic reflections and animations. Environment mapping and other high-end rendering techniques produce lifelike reflections, while vertex deformation and skeletal animation bring trees and banners to life with dynamic movements.
  • Global illumination. Unreal Engine 3’s built-in global illumination system, Unreal Lightmass, provides realistic lighting and shadows with minimal development resources.
  • Dynamic specular lighting with texture masks. Sophisticated graphics features impart a tangible quality to cobblestone roads and vivid reflective marble surfaces, while lens flares and light coronas add dramatic emphasis when panning across light sources. For more information, visit
