I worked on this project in the last year that I worked at BeyondSports.
The idea is that you can watch a match LIVE in 3D and have the advantage of seeing a simulated football match from all angles. You can change how the players look by changing visual themes. You can record a part of the match and then share it with other users like a certain popular app that 'some' people seem to dislike.
I worked mostly in implementing the 'BeyondSports engine' that visualizes a football match, that I designed and created together with a coworker.
Some other things I created for GameFace:
Shaders of the players
TextToTexture to create the textures on the players shirts
CameraSystem(not proud of how that turned out)
AutomatedDirector tells what camera's to use in specific orders depending on events in the match(penalty, corner etc.)
IAP created package that can take dynamic entrees to buy (and of course the buy calls/callbacks etc.)
NOTE: for some reason the app performs terrible, this was not the case before I left the company so I am unsure what is going on. This is obviously not the way the app usually behaves
