Let's daydream about the Tractor Beam special rule card (and ship modification card) that may come with an XG-1 Assault Gunboat and G-1A Mist Hunter .
Mechanics-wise, it may act like an ion cannon to start: roll a number of attack dice as a secondary weapon attack (Range 1-3), if you get even one net hit or crit, disregard the remaining dice, deal no damage, and the tractor lock has been established. The rolling of defense dice will allow nimble ships to escape the tractor lock in the first place. As a side note, you probably cannot tractor lock a ship whose base is larger than your own.
Then you need some kind of simple mechanic to represent the tractor beam's effect. Here are some possibilities:
1. Target ship is unable to move at all (sounds too harsh). Perhaps lose a single Activation Phase?
2. Target ship is only able to do green maneuvers
3. Target ship is pulled straight toward tractor beam ship 1 range increment (a bit fiddly and hard to do correctly, especially with regard to preserving facing, etc)
4. Much like when a stressed ship attempts a red maneuver, perhaps the tractor beam operator gets to choose the target ship's maneuver dial setting for the next Activation Phase.
I am tempted to say this modification can only be added to certain ships (the TIE Defender, Mist Hunter, and XG-1 all mention the use of said device, as well as capital ships and larger, of course). I don't think this should be added to an A-Wing, however...
) of remaining Rebel type ships, I suppose Wave 4 will be the last of this "Rebellion Era" go 'round, with the exception of some re-paints and whatnot.
