Among the Stars

 is a Fallout 3 quest and achievement in the Mothership Zeta add-on.

Walkthrough
Upon the beginning of this quest you are tasked with destroying three different modules on the ship, all in different sections of the ship, which are the Hangar, Robot Assembly and the Cryo Labs.

Before you venture into each section, you have the option of bringing one of the three specific captives that you unfroze with you to assist in destroying the modules. However, each NPC can only be brought to one predefined sector (like how Paulson can only assist you with the Hangar).

Hangar Bay
Your looking for the generator in the hangar, which is located at the back and at the top of the hangar. To get there take the stairs down to the space ship floor and go through the door open doors on your left. Walk through them and exit back out onto the spaceship floor. This is so that the aliens in the balcony can not see you. When you come out these doors, and your looking at the balcony, go up the staircase to your left and turn right at the top. Walk up the blocked door and near you on your left side is the switch to open it.

Walk all the way through corridors and up the stairs till you see the two drones, one is a support drone and the other is a guardian drone. Go left and follow the wall round and there is another blocked door, and hit the switch to open it. An alarm goes off and if you look out into the hangar you will see the room becomes filled with aliens and drones. Using the 'active Pylon controls' you can knock over and kill the aliens and robots. For me there was a steady, endless stream of this and they were not hard to kill with the pylons. However you need to be carefull because some aliens will inevitably go up the staircase from either side of you.

In the end I went down the staircase on the left which door is now open at the bottom, so now your back at where you entered the hangar. I fought off the aliens and went into one of the teleportation rooms on the hangar floor which the spaceship is on. I think going in there or atleast down to the hangar floor triggered the flow of aliens and robots to stop.

You now need to go back up to the balcony to the door where you set the alarm of. Walk in and directly infront of you is a blue switch. Press it and the generator elevates and so do 3 coolants. Like earlier in the DLC, activating all of the coolants will cause the generator to explode.

Robot Assembly
When you walk in, just follow the screaming worker alien. He doesn't talk to you or anything, but he leads you the right way. You should have gone down the stairs and not turned back on yourself, but gone straight on and round the corner. Keep walking straight on and go through the corridor.


 * Just a hint but on your right as you walk up to the corridor, there is a healing archway*

When you walk out of the corridor, follow the stream of partly assembled robots down to the end of the room. By this time I had a whole load of robots on me so remember to check your health. I took out the turret on the ceiling first and then focused on the robots. Once I killed them all you can take the guns off the guardian robots. They are an alien grenade launcher so not entirely accurate but very effective when you hit someone.

At the very end of the room, you should see all the robots going into a machine thats on the wall, and on the side of this machine is a blue robot symbol. There you can over ride the machine, causing it to explode and knock you over. Now there is a hole in the side of it which you can walk through into the next room.

In this next room awaits you at least 3 guardian drones, 5 support drones and I think two alien guys, one of which has an drone control device which is useful. There is nothing of use upstairs apart from 2 alien Epoxy. Underneath the upstair you will find a heal arch and from there you walk straight on, down the stairs onto another generator. After it explodes another objective is complete
