Check out some media from a UDK project I built called The Babylon Spire. This was an early project that helped experiment with some new concepts for Oculus Rift DK1.
As an exercise in level design, this project was lots of fun to put together, mostly because of the atmosphere. The rain and thunder, along with the lights and fog, created a really cool ambiance to work in. Thanks to Allen P. Smith for providing a really cool music track to go with it!
