Animated and captured in-engine.
One of the bigger parts of the UI I was asked to help out with whilst on the Zombie Army 4: Dead War project was the Mission Results screen. This screen was sequence and animation heavy, requiring a lot of iteration and testing. A good example of some of the work was animating the medal artwork (by the super talented Alex Gibson [http://linkedin.com/in/ajgibson] and Karla Lozano[https://www.artstation.com/karlalozano])
