|Sector||Jetsam of Saturn|
Shipyard AWO-43 is a Lost Sector in Jetsam of Saturn.
Fast travel to the Thieves Landing and summon the sparrow. Go left and follow the path till you reach Jetsam of Saturn. Take a left turn and once you reach the cliff go right and drop in the first cave on the right. Go through the complex and you will reach Shipyard AWO-43. Here, you will be attacked by Dregs and nasty Exploding Shanks. Clear them out, go right, jump down and eliminate Vandals shooting at you. You will come in a clearing where a bunch of ads, along with Zetix-7 await. It's a good idea to use a Super at this point, as you will be swarmed by the Fallen from the nearby ship. Just keep blasting the Servitor with heavy weapons and he will soon be destroyed.
