A level I built for Unreal using a variety of asset packs. This was more of an experiment to see if I could create interactive user interfaces that happened at random times. This was fairly successful, and using Unreal's blueprints system I was able to create a ui element that only appeared when the character was in the 'activation zone' for the object. That also enabled a sound, and, when pressed, would spawn in a gold brick on the top of a strange device.
