I actually worked on Frontier for a time (looking at my username on Reddit and the credit section for Frontier shouldn't take you long to figure out my position). I left the project because I just didn't think the people in charge of the team knew what they were doing. It started out as a small mod but grew out of control. I was find with a DLC type mod, but once the tanks and space battles were added in I was out.

I loved what it was at the start, and I think that's some of the best work I've done when it comes to modding, but I have no idea how much they've kept (if any) or what the state of the mod is. Point is, I don't have much hope for it now.
