This a recreation of Soldier 76's abilty: Biotic Field. I decided to make this one on the fly since i was playing with some friends.
Credits:
The biotic emitter is from: https://grabcad.com/library/soldier-76-biotic-emitter-1
I simply twisted it a little bit and added a simple animation on the brackets using the Animation tab in Unity.
