This one has the lately-omitted AI Hunter/Killer ships returning to take up a role in exo-galactic strike forces. Perhaps more interesting to more people are the forcefield changes: the blocking effect that was removed in the last patch is now back, but the various other forcefield improvements from the last patch have been retained: regarding teleporting enemy ships, etc.
Also fixed a couple of rare-ish bugs, and tweaked the hardened forcefields as well as the high-armor-piercing ships.
This is a standard update that you can download through the
in-game updater itself, if you already have 4.000 or later. When you
launch the game, you'll see the notice of the update having been found
if you're connected to the Internet at the time. If you don't have 4.000 or later, you can download that here.
