6 is Over Achiever: Reach Player Level 30
Even with the content restored, there's barely enough XP in the game to reach level 30. You need 435,000 XP to reach level 30. I have some tips:
--Kills in basic combat is the best way to advance. Whenever possible, kill anyone in regular combat. Dark Side characters will have an easier time getting to 30. Noncombat choices give less XP.
--complete all possible side-quests.
--Each mine you recover earns about 250 XP. Recover all mines. Avoid tripping them in battle, so you can recover them later. If allies set up mines, you can still recover them. On Dantoone, if you side with the settlers, they set up 16 friendly mines for you. Recover all of them for 4000 XP.
--Use security, not bash, to open everything locked. You earn some XP for this.
--Activate allies, like the robots when you have the chance. You get the full XP for their kills, and often a bonus for activating them.
--let all the Sith board the Ebon Hawk when you leave the fuel station. You earn no XP for kills with the turret.
