They aren't terribly complicated, but they certainly are things worth keeping in mind.
1) The Blast Doors. Each entrance to the Bridge has a blast-proof door that is only operable from the inside of the bridge. There are three entrances. It might be too thick for your lightsaber to do much good, but you don't know. If you can, it will likely take forever, and having all your slaves bottlenecked at one entrance will harm your assault.
2) The Energy Dissipation Fields. Certain sections of the bridge have fields that can be activated in the event that someone boards the ship and assaults the bridge... hmm. They will be a pain in the ass if pirates keep hiding behind them, but there's not much you can do about them as they individually activated by the pirates. Very good (and frustrating) cover.
3) The Anti-personnel Cannons. Cannons that resemble satellite dishes that are maintained by a gunner on the bridge. The gunner labels targets using the ship's computer, then lets the automated weapons loose! Heavy Weapons, no doubt.
Trax is not sure if these defenses are anywhere else in the ship.
