We've been playing around with the Unreal Engine 4 a bit over the first half of this year. We fell in love with it!
The first major project was created a couple months ago but we decided to publish it just now. This was our first major experience with the engine (that's why there's still some glitches in it)
It is available for download so you can explore it: http://www.nodevisual.com/a33-nodelive
Really hope you like it.
