A big feature of HK-51 Activated will be Section X on Belsavis, the site of the Republic's first attempt at a prison colony. Now the area will play home to new Dread Master antics. The area is meant to be "darker" and "edgier" than other content players have encountered and is being touted as the "coolest-looking area" in the game. Players will also find the wreck of the Fatality, which sets them off on a very special venture. (Hint: You're going to track down a legion of HK-51 assassin droids, and this whole thing is called HK-51 Activated, and you know that at some point you get an HK-51 companion.)
Players will be introduced to multiplayer quests during which they have to work together to move through an area without setting off traps or activating alarms. A new world boss, Dreadtooth, will be introduced. When Dreadtooth is killed, he respawns with a stack of Dreadful Resurgence, which makes him harder to kill every time he respawns with players in the area. Those stacks will dwindle if players leave, or they can be deliberately increased to make encounters more interesting. If interesting is what you like, you'll also find nightmare mode available for Operation: Explosive Conflict.
