The zhbg.zip file you have requested: Miscellaneous / Pre-Zero Hour Backgrounds - 7.5mb is not available. Perhaps try browsing all files for the game Star Trek: Armada II and upload any files you want to share or are missing. This is the only information we could locate:
Ok, a few backgrounds here that I was using for Zero Hour, though I've now found better ones.
The rest of what this is can be read via the ReadMe. The screenshots included as are all four quadrants, the first two being Alpha, then Beta, on to Gamma, and eventually Delta.I hope you like. They make for darn good screenshots ;)- Ash
