Anecdote: BioWare first showed off the trailer for the upcoming HK-51 companion during the recently concluded San Diego Comic-Con. Observation: The trailer can now be viewed by players who missed the convention, allowing everyone to see a first glimpse of this special companion. Caveat: It has not yet been revealed how players can acquire their own assassin droids, although hints have been dropped that the process will require a great deal of questing, possibly on both factions. Encouragement: If you aren't daunted at the prospect, by all means, take a look at the trailer and start clearing space on your ship for a new droid.
