Star Wars: The Old Republic has received a new trailer, this time for the MMO’s Operation Nightmare update. It all looks a bit mad and well, nightmarish. http://www.youtube.com/watch?feature=player_embedded&v=pnu8jLqXFhg For a complete run-down of what’s new in this latest 2.2: Operation Nightmare update, hit up the official Star Wars: The Old Republic blog. In short, guilds are a key focus. The team at BioWare Austin has also added in guild challenges and other features to get everyone working together, along with the most unforgiving operation bosses to date, as well as new achievements and the Kell Dragon equipment tier. What do you think of the footage above? Thanks PC Gamer.
