3) Is it possible (without specific script modding) to ensure that a certain kind of ship is always in a planet/SB assault mission?
Yep. EEK Planet/Base Assault missions took NW's idea of giving Lyrans a Orion Droner further by actually replacing any lost Orion Droner five minute after it dies so the Lyrans are not SOL, if their droner dies.
4) Is it possible to assign legendary officers to ONE kind of ship/base in a mission script without having the possibility of them appearing
in all enemy ships?
Yep. But, I thought there was a ban on Magic Photons??
5) Someone (or many people) was/were wroking on Andros a while back- did they ever get to be working? (he asks innocently...)
I got bored running around in my tac. warping Andron convertible. Then I hit a few too many planets and rocks and got amnesia about scripts and stuff.
