Beyond the Red Line is a FSO project that will be a standalone multiplatform game. The game is based on the second season of Sci-Fi's BSG. It is still in development and there isn't too much info on the game itself but you can download a tech demo here:

Make sure you try out the demo and let us know what you think.
And here is a small video showing off the Asteriod Field.
IIRC, this mod is pretty much dead after the split for Diaspora 🙁
I thought it might be. But when I contacted the some of the modders behind it they told me it was still in development. Both Diaspora and BTRL look great and just hope to see one or both of them. I know these will be standalone games and they take some time to develop, I just hope the FSO engine gives them all the tools they need to make it great.
