How to create a specific movement

Hey Guys,
I started using the unreal engine some days ago and want to create some games like “Stick Fight: The Game”. I personally like the movement of these little figures and I am trying to rebuiltd it with no success. Can anyone advise me how to design this movement?

Steam Website of “Stick Fight: The Game”: http://store.steampowered.com/app/674940/Stick_Fight_The_Game/

I hope somebody can help me out… (Sorry for my bad english I am german :D)
