Among the Stars

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

Walkthrough
The objectives of this quest is to destroy the three generators on the ship. They are in the hanger, the cryo lab and robot assembly. You have the option of bringing along with you one of the three people that were thawed out.

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. Pushing the switch to open it sets off an alarm. At this point, a seemingly endless stream of aliens and drones will come from the two doors that are now unblocked on the lower level. Using the 'active Pylon controls' the hostiles can be knocked over and killed. However not all of them will be killed and will need to be finished off in the normal fashion.

There are two healing archways on the top balcony which the PC can repair. The PC needs to have a repair skill of 75 or greater. Once repaired they can be utilized. The port door in which the damaged ship was brought up through, will close when all of the drones and aliens cease spawning and/or are all killed.

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. Exit the way you entered.

Robot Assembly
When the PC walks in, follow the worker alien. Go down the stairs and around the corner. Proceed straight on and go through the corridor. There will be a healing archway on your right while proceeding down the corridor.

Follow the stream of partly assembled robots down to the end of the room. You will confronted by several sentry drones armed with drone cannons. Regular drones will attack as well.

At the very end of the room, you should see all the robots going into a machine that's on the wall, and on the side of this machine is a blue robot symbol. There you can override 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, approximately 3 guardian drones, 5 support drones and a minimum of two aliens will attack the PC. One of the aliens has a drone control device which can be useful. There is nothing of use upstairs apart from 2 alien Epoxy. A heal arch will be under the second level. From there you proceed forward, down the stairs and onto the second generator. Exit the way you entered.

Cryo Labs
Upon entering the labs, hostile aliens will attack from the right. On the left there will be a room that is accessible by passing over the glass floor. On the wall next to the door is a switch which will unlock the room below. The unlocked room contains alien and wasteland items.

Proceed back upstairs and turn to the right. Face north and proceed through the open door. There will be aliens and drones in the room the player will enter. The drones sensors can be realigned (if the player has the robot control device) to target creatures that are hostile to the PC.

On both sides of the room there are switches. One activates the log and another thaws a ghoul and a raider. Upon leaving that room there is a similar room with the same cryo-storage pods. Activating them will release a ghoul and a raider.

Upon passing through that room, the player will come across an examination room. Activating the switch will seal the doors and freeze everything inside, including the aliens that are conducting experiments.

The next room contains two pods which contain soldiers. Elliot Tercorien will attempt to revive them. If they are revived before he has checked on their status, they will both be instantly hostile and fight each other to the death before then attacking the Lone Wanderer. If however, Elliot successfully completes his research, then they will join the fight to escape for a brief time before dying.

After either reviving or killing the soldiers, the player will enter the main cryo storage bay. There are several aliens on both sides of the bay. Throughout the storage bay there are numerous switches which, when activated will thaw it's contents. Usually ghouls and raiders. On the lower level, there are Super Mutants that when thawed will attack the aliens which will solve most of that problem.

After all the enemies are destroyed, face north and head down the corridor. This is on the second level. If you go downstairs, you are proceeding in the wrong direction. At the end of the corridor will be the generator. Destroy the generator. You may find that it is impossible to exit the way you entered and and it is easier to go right out of the generator room and then use the teleporter to go back to the beginning of the cyro lab.

Bugs

 * Upon entering the room with the two soldiers, the entrance doors may become locked and the teleporter is inoperative. This results in being stuck in this level. (confirmed XBox 360)


 * Karma loss will register if you die due to depressurization. (Confirmed XBox 360& PC) (Although it doesn't matter since it reloads the last saved game.)
