(Phase 1) Work for Boba Fett
1. Time to meet the Famous Bounty Hunter, and win favors with him. He wants you to kill a mark for him and bring back the marks gun as proof, will you do it?
2. You accepted his request and congrats, he sends you off, flying to Restuss, Rori. There you must speak with a informant, he has a bird like hair
3. His being stingy? Give the informant the package that will change his mind, and btw dont worry about his brother Boba Fett is taking care of him J
4. HAHA he finally comes around, to Dantooine space sector you go, probably best to go to hyperspace point closest to Space Station. There you intercept the smuggler, and follow him to your target
(Phase 2) AMBUSH!!
5. What the mark that lousy no good.no problem you got your ace flying skills and defeat the 2 ships that were sent to kill you.
6. After they die you search the debrie and find a location to Labor Outpost, Yavin EDIT: I ended up having to fight several mobs out there as well as the two for the mission. Needless to say by the time I was done I had no idea where the "debris" would be to search. Just go right to step 7 and forget searching space scrap.
7. You finally get to yavin and land, where you search for your mark and go to a cantina behind the star port. There you find a cook that knows him and ask him if you seen the mark lately. Off course the cook hating the mark tells you everything.
8. Off to Nashal, Talus you go, you get to the planet and start searching the cantina, hoping good luck, and there you find a Ithorian bartender who tells you he is in the last room of the cantina.
9. Upon reaching the last room you find a BH named Durge with your mark already dead and stuffed inside a box, hm.this could be troublesomethen Duren says Tell Boba Fett his next!
(Phase 3) Durges Demise
10. REWARD: You report back to Boba Fett and tell him of your happening, and Boba Fett becomes intrigued by this Durge, he hands you the needler back, not needing it anymore. Come back when your ready to do more bidding from Boba Fett.
11. So Durge wants a piece of Boba Fett, talk to Boba Fett and he sends you to the warren to search info to find where Durge is located at, The thing you are looking for is in the first big room fo the warren, by a PC term with green screen, there you must then escort a scientist out.
Phase IV
12. Once you get the scientist out he provides you with the passcode to access a lockbox he left in the backroom of the mining outpost cantina. Within that box is his datapad with all the info on Durge.
13. Head back to Boba Fett. He looks over the information and informs you that the "Claw" crime syndicate operates out of the Daeric hotel on Talus. He gives you either the DC15 rifle or Carbine at this point. Go to the hotel and speak with one of the two claw guards standing outside the back room. I chose to tell them I was working for Fett and ended up having to kill several before I could gain access to the room. Once inside the Bith in there tells you Durge was last seen in Deeja Peak on Naboo.
Phase V
14. Now head to Deeja Peak. When you enter the main courtyard some weak gray con battle droids will spawn and attack you. Dispatch them and head into the only house with a working door

Once inside another battle droid will spawn - kill it, then head to the basement.
15. In the basement will be a large box. Click on it and Durge will spawn and attack you (old school hand to hand style). He's a gray mob as well so kill him in a few hits.
16. Head back to Fett where you hand in Durge's helmet as proof (no you never actually have this in your inventory) and Boba rewards you with the KYD21 pistol (CL80 Spy).
Just finished this and wanted to elaborate on the information Skor posted while it was still fresh in my memory.
