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
The generator is located at the top balcony in the hangar. Kill all of the aliens in the hangar area (balcony across from where you walk into the hangar, hangar floor and uppermost balcony). When you come to the balcony across from the one you first entered on, push the switch to open up the sealed door and this will take you to the top balcony.

Walk all the way through corridors and up the stairs until you see the two drones. Go left and follow the wall around and there is another blocked door. It is advised that you SAVE AT THIS POINT. Pushing the switch to open it sets off an alarm. An endless stream of aliens and drones will come from the two doors that are now unblocked on the lower leve. Using the 'active Pylon controls' you can knock over and kill the aliens and robots. However you need to be careful because some aliens will inevitably go up the staircase from either side of you.

It is unclear what exactly stops the flow of aliens and drones, but at this point, go down onto the hangar floor and start taking out aliens. Having a lot of stimpacks is helpful, but if not, there are two healing archways at the top balcony that you can repair with a Science skill of 75. You will know that the stream has stopped when the floor below the spacecraft raises up and you can walk on it.

Now go back up to the balcony to the door where you set the alarm off. Walk in the door that is now open and directly in front of you is a blue switch. Press it and the generator and three coolants elevate. Like earlier in the DLC, activating all of the coolants will cause the generator to explode. Leave the same way that you came in.

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

Cryo Labs
On entering the labs an alien opened fire on me from the right on some stairs. After killing him head left and pass over the glass floor and on the side of it there is a switch which opens the door to the room below you. It contains some Human and Non - human items in there but really nothing special. Now going back upstairs go right and then look north and walk go through the open door. As you walk in immediately to your left is a robot which if you have the robot control device with you, you can re align its sensors and activate it so it attacks aliens. On the south west wall is a switch which if you press it, opens up another blue portal which must be linked some animal storage place because a naked raider and a glowing one came out and attacked the guard alien inside that room.

Going to the door on the opposite side of the room, leads you to a bigger place full of these container/portal things. Head left and there is a switch which releases feral ghouls and a raider onto the aliens and on the opposite side of the room there are some door controls which i rewired for a proximity explosion. *be careful in the main room because a feral ghoul reaver is one of the things that was released.

Going across the decks and through a corridor leads you to the testing room. There is a switch directly in front of you that freezes everything inside so you can kill all the wastelanders and aliens easily that way. Go into that room and then travel north into the cryo storage room. Turn the switch on, on your left and then go out the door on your left. On your left is a healing archway and on your right is a room which is probably full of the alien test subjects. There are 5 aliens inside this room, two of which have shock batons.

There are many switches in this room and pressing them will release supermutants and things like that to help kill the aliens. Once you have killed all these enemies go to the center of the room facing north and then look right. You should now be able to get the the other side of the storage where there are more aliens and more super mutants to release.

After killing all the enemies go to the center of the room, facing north and then head north. You will go into a corridor but don't go right down the stairs as that is just going back on yourself but follow the corridor round and on your left there is the generator.
