With Beta 4 less than two weeks away, things are starting to get pretty exciting here. We're in bug-fix mode on a ton of the newer features. For example, fleets are in and they're pretty fun to watch fight it out. There will be polishing on those screens until we ship I expect since making a fleet battle look cool is a lot of work.
I've been trying to tune the game play a bit as we wait to get the fleet stuff ironed out. Can't really do the AI with fleets until the regular fleet stuff is rock solid -- otherwise we'd wonder whose bug it is.
The music is starting to come in along with sound effects. Most of that won't make it into the initial beta 4.
Beta 4 and a few builds after that will be available to the public. After that, only users with "Diplomat" access or better will be able to access private builds so we don't ruin the surprises in the final game for players. Speaking of surprises, the campaign story has a pretty shocking ending which we hope people will enjoy.
