1) are romulans the only ones who can have nuclear mines?
Yes, hard-coded in the game.
2) if you give a PF a tractor, will it use it?
Yes
3) can you only have 1 PF per shuttlebay?
Yes - you mean per fighter squad, right?
4) I know that there is a Plasma/Drone that is hidden that is nerfed due to lack of coding. I also know that there exists a TRBH and TRBL - are those unfinished and act wonky? (aside from the UI which i know doesn't exist) or are they viable weapons
The TRBs work, on some SGO servers we had an 'Alien encounter" mssion where you'd have to fight Andro ships with these weapons.
5) The strength of a Fast plasma is equivalent to what other plasma? is it just a fast Plasma-S, G, R or does it have its own damage curve.
It's 40 point torp, bigger than S, smaller than R
6) does the plasma snare do any damage, or does it just slow the guy down. How long does the effect last?
Not sure, try to ignore the Taldren X-ships.
