Jump all the way up and go into this door.
Go down, deal with the Dark Jedis, and go into this tunnel.
Go out; kill the Cultists, and go left.
Go through the doorway and to the far side of the room, look down and go into this hole in the wall.
Hop down and go into the next room, kill the baddies and go down the stairs.
Kill the Dark Jedis here, and keep going into the lava filled room.
Go around the lava and into the next room, go straight and bash the two support pillars.
Kill the Jedi here, then slice these two chains, jump up into the now open roof. Go over the tomb behind you as you come up, and go into the door for end level.
Almost done with the last level!
