Can you elaborate your question a little please? Do you mean where I got the file to mod this or how to obtain this specific battle suit in the game?
Both.
Ah, well, I am not sure in game. I am just towards the end of chapter 4, but I assume that you will get it one way or the other once you progress further enough. As for the file itself, just google around and add "Model Resources" in your keywords and you should find them.
Thanks. By the way great work. Looking forward to your next piece of art.
