So having played Rogue Company for a good while and getting to know the characters in that game, I think they would be a good fit for Xcom. Each of the characters and their voice lines could fit right in since they have defined roles in RCO and their voice lines don't make any references to the game they're in. I would attempt to do this but I don't have a clue of what I'm doing when it comes to 3D models. Anyone interested in creating a mod for RCO characters, I have a couple of ideas for a few starters:
These characters have relatively simple outfits apart from Saint and maybe Dima.
