Flashpoint: Kaon Under Siege is a completely new and unique group combat experience located on Kaon, a planet in the Tion Hegemony, a strategically important sector of the galaxy that has remained neutral, groups of up to four Republic or Imperial players must race to Kaon to eliminate the Rakghouls outbreak, securing the allegiance of the Tion Hegemony for their respective sides. This Flashpoint will be available for level 50 characters only and will feature Normal and Heroic modes.

Operation: Karagga’s Palace is a continuation of the game’s second launch Operation. In the Operation, teams of 8 or 16 players will face off against Karagga and the Hutt Cartel after the Hutts abandon their famous neutrality and breach agreements with both the Republic and Empire. Concerned by the threat of another combatant in the war for galactic control, both factions send teams of their most powerful heroes to confront Karagga and determine his intentions. This Operation will feature Normal, Heroic and Nightmare difficulty modes.
