Animation Doubt?

Hello Guys, I have a doubt whether a particular animation is a 3d or 2d animation. Just see this video from time frame 0:30 and watch the character who is firing. I feel it's 2d and done either in sprite animation or skeletal animation (using spine etc). What you guys think about it? https://www.youtube.com/watch?v=XpOvvCxLi0w&t=536s I want to achieve this animation using 2d skeletal animation in Unity but having problem while rotating the character around the fixed point ( hip part of the character).
