We'll call it a go with three successes.
You guide yourself through the maze of maintenance tunnels, moving toward the fighting by your own path to gain an advantageous position when you join in.
Eventually you come to what you believe is the correct corridor, and peak out. You do so just in time to see the Rocketeer break the arm of a Wing Guard and smash him to the ground. He grabs the officer's pistol and starts shooting down the corridor.
It is hard to move about in these tunnels, mind you- it will be Agility rolls to successfully attack without tripping over wiring and pipes. You pass just fine.
The Rocketeer only sees you at the last minute, diving to one side when you bring your lightsaber up to deliver a lethal surprise blow. He has a Defense of 3 from Close Quarters Gunman, so you roll 12 dice. The Rocketeer takes 13 damage as your lightsaber flashes through a series of pipes next to him, showering sparks and coolant into the maintenance tunnel.
The Wing Guard members still standing are in the junction, just before the tunnel the Rocketeer is hunkered down in. They hold their fire, not wanting to shoot you.

You have also healed 5 damage from bruising in the bar fight.
4-2, Rianna becomes a flurry of purple as she lashes her lightsaber out at the Rocketeer again and again. He is able to handle himself in close quarters and taps Close Quarters Gunman for added Defense, reducing Rianna down to six dice. She doesn't get the full four successes, but three is still enough for 18 damage.
The tap also gives the Rocketeer extra dice, for a total of 16 dice. Nine successes is 11 damage as he blows holes in a pipe just above Rianna's head, this time spraying her with freezing coolant.
Unfortunately for him, his dice total is a multiple of 5. Rianna responds by slicing the pistol straight out of his hand with a Riposte, for 7 extra damage.
The Rocketeer sneers unpleasantly and flexes his fists.

1-3, the Rocketeer drops low and tries to sweep your feet out from under you. His roll is not spectacular and only deals 5 damage, and you hop lithely over the kick. Sadly for the Rocketeer, he triggers another Riposte! You sweep your blade down at his leg, missing only by a fraction and scraping it along the floor. He takes 11 damage from the Riposte... and then he ripostes your riposte with a Street Fighter tap! He rolls aside and punches you in the thigh for an extra 4 damage. And then your actual strike, as you drive your lightsaber down into the floor in an attempt to skewer him to it. He rolls clear and hoists himself up quickly with some of the piping, but the effort costs him 10 damage.
A vicious exchange! The Wing Guard don't dare fire into the fray. Without Eagle Eye in these tight quarters, they are just as likely to blow through you as they are the Rocketeer.
