The December update to the UDK has brought us Epic's latest engine updates as always, but this time it's including support for iOS and the entire code and content for their Epic Citadel game and an additional castle map for it.

The entire update focuses on the mobile support as you might imagine, but there is more updates in there for the more traditional user too. Here's some cut and pastes from the update page in case you are still hanging out here:




NEW! iOS Support
Brand new features and content that users will immediately notice are:

  • Build levels, visually script gameplay events and add visual effects for mobile applications using the Unreal Editor and its major tools, including Unreal KismetUnreal Cascade and Unreal Matinee.
  • Superior rendering features for mobile development, including Unreal Lightmass global illumination accelerated by Unreal Swarm distributed computing.
  • The full source and content for the “Epic Citadel” App, plus an additional castle demo map.
  • UDK Remote:  A handy tool that enables iOS devices to serve as wireless controllers with full touch and tilt functionality for testing games on the computer.
  • New Unreal Frontend system compiles scripts and deploys builds for multiple platforms with the simple click of a button.
  • Mobile Previewer: Preview your application locally using a fully feature OpenGL ES 2.0 renderer with mobile input simulated.
  • One-click Deployment: Easily deploy your application from the Unreal Editor to your iOS device with only one click.
  • Next-gen Mobile Graphics: UDK's highly optimized mobile renderer has support for per-pixel lighting, environment mapping, precomputed visibility and more!  And of course, Unreal Lightmass computes stunning light and shadows to bring your scene to life.
  • Unreal Kismet Visual Scripting: Artists and level designers can string together actions, inputs and events in Unreal Kismet to dictate how the world flows and how the player interacts without having to touch a single line of code.
