This is a big mech robot plugged in to Movement Animset Pro controller in Unity. As you can see, motion capture animations work great on anything, that walks on two legs. If you bought Movement Animset Pro, you are pretty much set for life, regardless of what type of game you are making, as long as your characters can stand in t-pose :)
