I don't think i've seen this talked about yet, but I think both of these would be excellent additions for wave 3. These are both from "Tie Fighter" and were used fairly extensively in that game. You could equip your ship with a tractor beam, which would force an enemy ship to move in a straight line if caught in it, or you could equip it with a jamming beam, which interupted and enemy's target lock on your ship. The MAG Pulse Missle was only in a few missions, but it was a rebel invention carried mainly by the B-Wings in the game, and it essentially drained all of a ship's laser cannon energy when hit.
These could easily be translated to X-wing miniatures. The tractor beam could be used as an action (or a secondary weapon), and could force a ship that it was facing (directly facing, possibly using a seperate beam weapon firing arc) to pick a striaght maneuver for it's next move (or at least some kind of limit to it's move options) and the Jamming Beam, using the same idea, could prevent ships from being able to aquire a target lock. The MAG Pulse missle could reduce a ships primary weapon (and maybe even secondary weapons) value to 0 for a certain ammount of turns (maybe 3). And, if it was B-wing/Tie Bomber exculsive, it would make these ships highly valuable for the next wave.
I love the idea of all of these upgrades. Using a B-Wing to hit a firespray with a mag pulse, and essentially removing it from the game for a few turns. It doesn't do any damage, but it seriously affects how you would be piloting all of your ships. And likewise with the beam weapons, again possibly a B-wing/Tie Bomber exclusive, would complety change the meta in my opinion.
