Bioware has announced the imminent arrival of a new companion for players in Star Wars: The Old Republic. The HK-51 is an assassination droid and is shown off in all its glory in a video on the official site.

Buried deep beneath the icy surface of Belsavis rests an army of the deadliest, most feared machines in the known galaxy. Thought to have been lost when an Imperial freighter was destroyed, they have recently been rediscovered by a group of renegade Sith Lords. Now both the Sith Empire and Galactic Republic seek to control these dangerous weapons for themselves. Those who are brave enough to venture into the wreckage will emerge with a powerful new ally.

Check out the trailer on the Star Wars: The Old Republic site.
