While some talk of a Homeworld 2 mod continues, NewCommanderondaBlock had updated the original Homeworld mod, Fleet Action. The ship files have been updated slightly to enhanced playability. Most original ships have been replaced by Wing Commander equivalents. Previous crashing issues have been narrowed down to the Weapons Effects Pack, so don't use that.
The pack contains Kilrathi (race 1, Kushan), Confederation (race 2, Taiidan), Border Worlds (Pirates 1) and Nephilim (Pirates 2). The Border Worlds and Nephilim ships are only for maps with them built-in. All you need is the original Homeworld. Install it by extracting the zip file to your Homeworld directory. To uninstall, delete the folders "r1," "r2," "p1," & "p2" and files that end with ".ll" and ".script" that are in your main Homeworld directory. Please note, that this mod is NOT compatible with Homeworld: Cataclysm or Homeworld 2.here.
