Companion Appearance Customization guide with screenshots of different customizations (Work in Progress).

You obtain this special companion through a quest chain that starts in Belsavis’ Section X. The quest chain consists of collecting HK-51 parts and will require you to be level 50 and have at least a level 15 alt of opposing faction. You will also need to run two flashpoints as part of the quest chain.

Guide to obtaining HK-51

There are four parts to the quest chain of obtaining your very own Hunter-Killer droid.

1. Belsavis – Section X – Frozen Lake -Fatality

The chain starts in Section X on Belsavis, which you can reach by shuttle once you reach the planet. The quest (Fatal Errors for Empire and The Fatality for Republic) is started by a droid (G0-A1 for Empire and B6-31 for Republic) and it happens inside the ship Fatality. You go to the Frozen Lake part of Section X and talk to NPC there (general Avrun for Empire and general Bren for Republic) who will tell you to enter a wreck of the ship Fatality.

Frozen Lake is in the NW part of Section X

Although the quest is Heroic 2+ with good gear and a healing companion you can probably solo it and the only real problem could be the last boss with two strong mobs.

2. Theoretika

Next, you will have to travel to the Uncharted space and visit the ghost space ship Theoretika.

The Theoretika

The Theoretika

You will be exploring this derelict ship and attempting to unlock its sections in order to get your hands on the HK-51 schematics. At the end you will face a champion mob, that can be soloed with decent gear (or with some help from poisons). You will start on Deck 4 of Theoretika. There are 4 rooms in the middle and one to the north. What you need to do on this deck is find an engineer’s id badge that will get you into the engine rooms where you will find a power cell that will help you open the door to Deck 5. Along the way you will be able to collect datalogs as part of the bonus quest Fate of the Theoretika.

Engineer badge map

You will find a corpse with engineer's badge at this location on Deck 4

This badge will help you get into the engine rooms to the south

Once you get the engineer’s badge go south and you will be able to open the engine deck doors. All the way south, in a contaminated area (you will lose health just by standing there) you will find an emergency battery that will help you power up the door to the next Deck. Pick it up and go north and use it in the emergency power socket.

You use the battery at the socket in the northern room of Deck 4.

deck 5 door open

This opens the door to Deck 5, whose location on the map you can see above.

There is a bonus mission that will have you collecting datalogs from dead crew members. You will find three datalogs on Deck 4 and two on Deck 3. Two datalogs on Deck 4 are easy to find, while the third one is hidden inside the locked room that you will access later.

These are the map locations for two easily found crew datalogs on Deck 4

On Deck 5 you will find two locked blast doors to the left and the Main Engineering room partly filled with water to the right. There is a circuit breaker that you will need to activate that will unfortunately electrify the water. You will have to jump over pipes to avoid the water and leave Main Engineering. You will then find a corpse with security badge that will help you open the last room on Deck 4.

jump to pipes

Once upstairs jump on crates and than jump onto pipes

jump on ledge

Jumping onto pipes can be tricky, just move back a bit. Once you manage to jump onto the 2nd pipe you just need to jump up onto this ledge.

cross beams

You need to go across the beams to get past the electrified water

route to barrel

Follow this route across the beams to get to the exploding barrel

At the end you will find a barrel of hazardous material that, once activated, will explode and open a passageway for you to go through

jump down

Once the explosion opens the passage just jump down and exit Main Engineering to the North.

Once outside you will find a corpse that contains security officer's id badge

Loot the id and go back to Deck 4 to unlock the room you couldn't enter before.

deck 4 last room map location

Go back to Deck 4 and enter the room shown on the map above.

It's a Trap! Thanks to this guide you will be able to find an exit quickly and easily.

move crate

You first want to move this crate in the NE part of the room. This will reveal a hidden panel.

sabotaged control panel and fuse

Behind the crate is a sabotaged con trol panel inside which you find a broken fuse. You need to find something to replace that fuse with.

replacement fuse location

You fill find a replacement "fuse" in the SW part of the room

Once you replace the fuse pick up the datalog and the medical id badge from the corpse inside that room. This will help you go inside the Medical bay on Deck 5 where you will find the last datalog and something that will help you defeat the last boss.

enter the medical bay

Enter the medical bay to find your last datalog and create a poison that will help you against the last boss

create nylite poison

Pick up the empty stim injectors and go to Nylite canisters (there are full ones in SW corner of the room) and fill them

specimen gamma 19

All that is left for you to do is go to Deck 6 (to the north of Deck 5) and kill Specimen Gamma 19 (remember to use the nylite poison in your Mission inventory)

3. HK parts hunting

Next you will go on a scavange hunt to pick up 7. HK droid parts scattered around the universe.

1. HK primary transistor – Tatooine – Outlaw’s Den

The first part can be bought at a jawa vendor Collector Kezzit in Outlaw’s Den on Tatooine. If you have the legacy perk you can teleport there instantaneously. Wrapped HK transistor you need can be bought for 125k. Also, if you do not have the Burba Seismic Excavator / Scanner in your inventory already you can buy one here as well. This is used to find two other parts later on so it is pretty important.

Vendor location on Tatooine for the first HK part

Wrapped HK transistor

Buy Wrapped HK transistor from the vendor

2. HK chassis – Taris – Endar Spire crash site

This is probably the most tedious part of this whole quest chain. You need to use the Burba Seismic Excavator / Scanner around the Endar Spire crash site until you find the HK part. You basically activate the scanner and it scans 25m around you fore the part for 16 seconds. It can take a lot of time to cover all that ground with the scanner. Luckily, if other peoople are searching the area as well you will be able to find it much quicker because once one of you finds it everyone in the area can loot it (it stays spawned for a minute or so after being excavated). I found my HK chassis at -92,-207 and the other reported coordinates are {90, -100}, {-51, -142} and {-120, -157}.

Found HK Chassis

Once you find the exact location of the component the scanner will excavate it.

Just loot the unearthed component

global map hk chassis taris

3. HK AI regulator – Coruscant – Jedi Temple ruins

If you are Empire you will have to have a Republic alt of around lvl 15 to get to Jedi Temple ruins in Coruscant and scan the area for the next HK part. Once found the item is in a Bind on Legacy container so you can send it to your main. The entire lower part of the Jedi Temple ruins is a possible place to find the component so you need to be very patient and very thorough. Worst … game … design …ever…

4. HK motivator – Dromund Kaas- Dark Temple Grounds

Same as with the Jedi temple Ruins you need to have at least a level 15 Empire character (or a high level babysitter) and scan a large area of Dark Temple grounds to find the next component. Item is also legacy bound so you can mail it to your alt.

5. HK Power Core – Hoth – Glacial Fissure – Ambria’s Fury

This is found in the NE part of Glacial Fissure area on Hoth near the Ambria’s Fury wreckage and it is a lot of ground to cover. People say that the components are usually found closer to the ship so you do not have to wander off too much.

6. HK Weapons Protocol – The False Emperor flashpoint (normal mode)

Kill HK-47 boss in The False Emperor flashpoint to gain this component.

7. HK Loyalty Chip – (The Foundry/Maelstrom Prison Flashpoint Hard Mode)

The last part is appropriately held by Revann himself in the Foundry/Maelstrom prison flashpoint, which you will need to complete on hard mode.

4. Back to Fatality

All you need to do now is go back to Section X on Belsavis and make your way through the ship and some enemies to get HK-51. Congratulations!

    great guide! thx a lot. But just to clarify: you say you need a lvl 15+ alt to scan the opposite faction area (temple areas) but how does the alt get the scanner? Is it also bound to legacy? Or do they need to buy one in Outlaws den?

    • Comment by The Spy (admin) made on November 23, 2012 at 1:32 pm

      You just send it to your alt by in-game mail. It is legacy bound I think.

  3. Comment by bandaria made on November 24, 2012 at 1:40 pm

    The excavator found the hk part on Taris, but when I tried to loot it, it told me I don’t need it right now. What gives?

    • Comment by mpdugas made on February 12, 2014 at 4:42 am

      You must have acquired the schematic from the Theoretika first; you can get the PvP and cross-faction pieces at any time, but the single character who does the whole quest line must get the schematic before they can ‘loot’ any of the remaining parts.

  4. Comment by Aurak made on November 29, 2012 at 3:54 am

    Currently, Jedi Knight and Sith Warrior (both Advanced Classes of each) are ‘bugged’ with getting HK-51, and they will get him without any gear at all. To my knowledge, there is no ETA on when this can be fixed. With all the people that try and sell his gear, you could just farm up the 1 million to ‘buy’ him early with an alt, and just make one specifically for stripping down HK, then mail the gear to the Knight/Warrior.

    • Comment by Tuskin made on November 29, 2012 at 7:56 pm

      Uhh, I have a Sith Warrior and Knight, I got Gear with my HK-51.

      It is a known bug, not everyone is getting what you discrbed.

      Unless this is a fairly recent issue?

  10. Comment by Ezuel made on January 18, 2013 at 2:41 pm

    theres a bug. I was at the final part of the chain and grouped with a friend who wanted to start the chain. We entered the ship on his quest and found that my mobs had joined them. This becaome apparent at the end when we confronted not only the dread master leadr and two DM gunners but Lord of Agony was in front of them.

    We resolved it by him abandoning his quest and we finished mine, then he started his again and everytihing from that point was as it should be.

  11. Comment by Ezuel made on January 18, 2013 at 10:42 pm

    for affection I found at rank 1

    Weapons 70
    Technology 35
    Military Gear 35
    Trophy 35

    Also if you use a higher rank while rank 1 is at above rewards, then the rank 2 will be 1/2. But when for instance rank 1 drops to 35 then rank 2 will become 70 (for weapons).
    Economically, rank 1 is 200 credits and rank 2 is 600 credits. So it’s cheaper to continue buying 2x rank 1 and feeding you companion (for a cost of 400 credits and 70 affection) as opposed to forking out 600 credits for 70 affection (weapons)

    Hi everybody.
    Once u got the droid, ure given a pack with parts to equip the droid with, but the droid is alredy equipped with the same stuff (blaster, cores and all that stuff).
    My question is, if i unlock the droid for the rest of the characters qith the legacy perk, will it be equipped as well, or i should have saved that box to equip the droid?
    Thanks in advance.

    Apparently no one part after the Jawa is guaranteed to be a the location when you use the scanner/excavator… You can find a part you already have. (Searched on Coruscant, found the part… and I was told I already had it.) I have to agree that is poor game design.

    • Comment by mpdugas made on February 12, 2014 at 4:47 am

      No, once you get the main HK-51 legacy unlock, each character in the legacy can buy the unlock for their character after level 10; I paid 340 CC for it every time I picked it up.

    Taris location found at 0,-112

    still ran around for 2 hours looking for it though. People coming onto forum now to look for it, I advise the following.
    1. write down all the locations that people have posted.
    2.You will see that the coordinates encompasses the area directly to the left Foward Outpost Alpha, where the 3 ponds are.
    3. start in one corner, and sweep from one side to the other. Then move to the next line and do it again and again until it shows up.
    4. Having a group really is wise because you can cover more ground quicker.

    Good luck, and thank you to all who posted their coordinates!

  34. Comment by rebublicunity made on December 10, 2014 at 5:47 pm

    I have found that the hk parts move a maximum distance of 50 meters from where it was last found. For example, I found the taris one 5 m away from where it was last found. So if reported coordinates aren’t working try this, I found all the parts in two – three days using this system.

    • Comment by Gonarm made on October 7, 2015 at 9:39 pm

      I bit late to be of use to you, but it may perhaps help someone else: All the HK components are character bound, the exception being that the one’s from Tatooine, Coruscant and Dromund Kass are packaged up when first received, and its the packages that are bound to legacy.

    So, there is actually a total of 7 datalogs for the bonus mission on the abandoned ship. I was pretty lost when following this guide because it only has a datalog count of 6. There’s actually 4 datalogs on deck 4, not 3.
