Star Wars: The Old Republic developer diary outlines features of the HK-51 update

Star Wars: The Old Republic's 1.5 update won't just add the appearance of HK-51 — the latest in a line of organic-hating droids — to the MMO; a slew of other features are coming too, as discussed in the game's latest developer diary video.

The update, which is expected to launch soon and is currently live on the game's test servers, adds a new explorable area on the prison colony of Belsavis, a new world boss which becomes more difficult every time it's defeated, new armor and mounts and, of course, a massive storyline involving the assassination droid HK-51.
