What am I even looking at? 
So glad I decided not to get into game animation. I wish I could upload my AM work, but there's probably a policy against that…
A walking animation of course, can't you tell? It's so obvious. *sarcastic voice 
I'd love to see them though ^^
I'm currently working on a few animations, just the little things we didn't get in the pack we purchased. Sitting idle, flipswitch etc.
So, what can you make using that software? Sorry, I'm just not familiar with those kind of programs.
Unreal is an game engine. Let's keep it simple: it's the collection of all the elements of the game. You create the levels in it, mechanics, lighting, everything.

We just finished the new trailer for our game btw. I'll share it when we release it ^^
