HK-51 is a HK assassin droid built during the Old Republic era. He is an available companion for all players, regardless of faction or class, to acquire at Level 50. He is also available through the Legacy System.
Level 50 players will be directed into the crashed Fatality cruiser in Section X, where they will have to fight their way through Dread Master forces to the cargo hold. After players defeat all the enemies, they will receive the cargo manifest. They will then depart to an old Czerka ship, where they work their way through the ship to find the schematics for the advanced droid. After that, players will have to travel on a galaxy-wide quest to find replacement parts. The locations of the parts include:
After recovering the parts, players will return to the Fatality, where they will have to defeat a final rogue Sith before getting HK-51.
As HK-51 specifies, he is designed for combat. When you get HK-51, he will come fully geared with orange-quality gear, plus a deadly sniper rifle and vibroknife. All his abilities are Rank 50. Every time HK-51 assists in defeating an enemy, he will acquire a buff called "Target Eliminated".
HK-51's has very few abilities, but they are worth describing.
HK-51 on Belsavis
Sith Empire version:
Galactic Republic version:
"The droid designated HK-51 is cold, calculating and incredibly lethal. Housed in a sleek body resembling an antique Systech Corporation protocol unit, this HK-series assassination droid lay dormant in the hold of an Imperial vessel for many years. Whatever HK-51's original programming dictated, he pledged absolute loyalty to his new master upon his reactivation.
HK-51 is a model of ruthless efficiency. His assassination protocols deteriorate unless they are put to frequent use. This leads to a constant acquisition, pursuit and permanent removal of qualified targets that would be seen as an obsession in any living being. Beyond expressing pride in successful assassinations, HK-51 has little patience for the trivial emotional problems of organics."
