Beta 4d (Stardate 11.11.2012) —
Major Changes:

  1. Converted over to Final Frontier Plus 1.81 as a base mod - this should fix any game wrecking bugs (like the no build bug) and has pretty map graphics!
  2. Completely rewritten AI ( This was a major pain but the game now FLIES! Slow downs are minimal to non-existent, even on slower machines.
  3. All Videos are now working including the Transcendence Project videos.
  4. All the other cool stuff you've come to know in the FFP mod.
  5. Borg now appears as some barbarian classes.
  6. A small change in the tech tree.
  7. Some Graphical and sound Improvements and added text.
  8. New Unique Units for Federation, Klingons, and Romulans.

What is not included:

  1. About 2/3rds of CIVS are not in this release and hense not their unique ships or buildings. Since I am going with a whole new system, I'm adding in the civs one at time, so you'll only have 7 civs to choose from in this release.
  2. Special Abilities such as cloaking device, Red Alert, and Assimilation are not yet up and running.
  3. Certain Promotions are not included in this release.
  4. Graphics and sound are "unpaked"
  5. * Star Trek "events" have not been added yet

It will probably be a few releases until the game is fully restored to it's previous design, but as I add each Civ, I am bringing them up to their full potential, which I've been meaning to do for a while now any way. I figured the most important priority was to fix the bugs and the speed issue so the game is at least playable all the way to the end.
