Epic Citadel is a tech demo developed by Epic Games for iOS to show off the Unreal Engine 3 running on iOS devices. It was also released for Android on January 29, 2013. The application allows players to explore a medieval landscape without being able to interact with it otherwise. The application further has a built in benchmark mode and a "guided tour" mode. Nonetheless this demonstration garnered significant attention as it showcases a free SDK called Epic’s Unreal Development Kit (UDK)[1]

The game uses dual zones with touchscreen control that are mapped as virtual joysticks. One controls the camera angle while the other controls the motion of the camera. The tech demo allows players to navigate through a fictional castle realm with various areas such as a circus bazaar, a river and a cathedral.[2] The artwork of this demo was created by Shane Claudie and the program itself was created in eight weeks by a small team of programmers at Epic Games using the UDK.[3]

The tech demo was a precursor to the video game, Infinity Blade, for iOS which was released on December 9, 2010.

On January 29, 2013, the app was launched on Android, with exclusive benchmarking features and the iOS version was updated to version 1.1, adding support for the iPhone 5/iPod Touch (fifth generation) as well as optimized graphics for the iPad with Retina Display.

The application is available for the wider variety of Android platforms (works for 2.3 and up) e.g. via the Google Play web page and via Google Play Store application.[4]

Using additional technologies such as the C/C++ to JavaScript cross-compiler Emscripten, the application was ported to HTML5 supporting run time environments such as the Firefox web browser (at least version 22 or higher; underlying platforms might be e.g. Windows 32/64 bit, Linux, Mac and others) where by the means of WebGL a pretty high grade of hardware support, and thus execution speed is achievable and running full screen is quite possible.[5]
