Very cool, thanks for your help! Hope you add things like turrets, vehicles, and shield walls/destructible terrain. Watching the video again it reminds me of Battalion Wars, Star Wars Battlefront and Battlefield Heroes with way more fun abilities. Hope you add capture points.
There are a lot of voice actors who will offer their services for unpaid work/in-game credits, maybe to add vocal commands or grunts, or a more narrative multiplayer mission like what Titanfall/SWTOR does before and after a PVP match.
I love third person games in general and your game brings back a lot of memories 
, definitely will keep up on it!
