Among the Stars Among the Stars is a " Fallout 3 " main quest and achievement in the " Mothership Zeta " add - on . Detailed walkthrough . Destroy the generators . This quest is activated upon reaching the engineering core with the objective to destroy three of the ship ' s generators located in the hangar , cryo lab / cryo storage , and robot assembly areas , in order to gain access to the decompression chamber to proceed further . Cryo lab / Cryo storage . Elliott Tercorien will assist in the cryo lab area if asked . He will not rejoin the party if asked to leave after having already visited the area . Having Elliot in this area unlocks the unique ability to create cryo mines and cryo grenade s . Upon entering the labs , hostile aliens will attack from the right . The left room is accessible by passing over the glass floor . On the wall next to the door is a switch which will unlock the room below , containing alien and wasteland items . Proceed back upstairs and turn to the right . Face north and proceed through the open door , and there will be aliens as well as drones in the room . On both sides of the room there are switches activating one alien captive recorded log or thawing a ghoul and a raider . Upon leaving that room there is a similar room with the same cryo - storage pods . Activating them will release another ghoul and raider . Entering the next room , the Lone Wanderer will , through a window and an open door , observe an examination room with some aliens conducting experiments . If Elliott is accompanying them , he will shout out that the aliens were experimenting on the members of his former squad , and will then proceed to hit a control under the window . This will seal the doors and release freezing gases into the room , killing all aliens inside who will be seen banging on the window pleading . The room itself contains two pods with Elliott ' s former comrades : Private Beckett and Sergeant Daniels . With Elliot present , the options are available to leave , euthanize , or try and revive them . If they are revived before Elliott has checked on their status , they will both become instantly hostile and fight each other to the death before then attacking the party . Complete research to restore his squad members ' memories , until he tells the Lone Wanderer that it is safe to trigger the release switch . The two soldiers will then join their party within the cryo - lab and storage , until they inevitably die due to damage - over - time by the poisonous substances administered to them by the aliens in their experiments , provided that they survive the ensuing battle . Afterwards , the main cryo - storage bay will be entered , in which there are several aliens and one automated turret , each on the two upper level strips as well as on the area below . There are switches to release ghouls and raiders in cryo - pods on the upper level . On the lower level , there are two areas with two pods each containing super mutant s ( leveled right up to super mutant overlords ) . They can be released by switches on the upper level , just above them . After all the enemies are destroyed , face north and head down one of the corridors on the upper level . At the end of the corridor will be the generator to destroy . There are four alien captive recorded log s located in the cryo lab and two in the cryo storage . Robot Assembly . Somah will assist in the robot assembly area , if asked in the engineering core . If Somah is brought into this area , she will disappear through a teleporter , telling them that she will try and fiddle with the teleporter controls . Head downstairs and to the right . Straight ahead is a corner shelf in an area abundant with alien epoxy . On one of those shelves and on the floor , one can find five units of alien power cell s ( 2 x 12 , 1 x 20 , 2 x 50 ) . Back down the main hall , there is a healing archway to the right . Upon entering the second room , turn right . Behind the pillars and against the back wall , there are several ( 4 ) biogels . Follow the stream of partly assembled robots down to the end of the room . If present , Somah will suggest blowing a hole in the assembly line ' s casing to proceed to the next room . While shooting at the glass is ineffective , there is an access panel where the assembly line exits into a wall , which can be activated to cause an overload . The resulting explosion is rather large and forceful , so back up . Entering a new area through the resulting hole causes a confrontation with several guardian drone s and support drone s , as well as a small number of aliens . One of the aliens is enormously strong and has the useful drone control device , which can be looted from their corpse . A healing archway will be under the second level , and from there , proceed forward down the stairs and on to the generator . Hangar Bay . Paulson will assist in the hangar bay area , if asked in the engineering core . 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 going to the balcony across from the one on which they first entered , push the switch to open up the sealed door and this will take the party to the top balcony . Unactivated drones can be activated with drone control device if you ' ve been to the Robot Assembly and gotten it , or you may just destroy them for loot . Walk all the way through the corridors and up the stairs until an encounter with two drones appears , if they have been activated . Go left after dealing with them , and follow the wall around and there is another blocked door . Pushing the switch to open it sets off an alarm which will begin an alien retaliation . At this point , a stream of aliens and drones will come from the five formerly blocked doors on the lower level , three of which can be seen from your vantage point . Activating the five pylon controls will send nearby hostiles flying , damaging or obliterating them . However , they also make a large area unsuitable for your mines . Some enemies will run to you through the two corridors , and two will come from the door with the switch of alarm , whom you can ambush with mines . Once this encounter has been dealt with , the door leading to the area ' s generator will become unblocked . Conveniently , there are two healing archways forming a path between the generator room door and the balcony overlooking the hangar . Also of note : by the end of the battle , a hatch raises into place below the levitating alien craft ( the recon craft Theta ) , completing the floor beneath . Gain access to the upper level . Once all three generators have been destroyed , the decompression chamber becomes available . Enter the chamber and put on the spacesuit looted from Colonel Hartigan . Press the room ' s single control switch , which decompresses the airlock , allowing the Lone Wanderer through several doors to a new area , the space walk . Along the way , several dead aliens and an optional side room with two containers and several ( 4 ) alien biogels can be discovered . While in space , the Pip - Boy 3000 cannot be accessed , weapons cannot be drawn , and the rest option cannot be utilized . While there are aliens that can be seen running below the glass , they cannot be interacted with and can be safely ignored . During the space walk , three exposed panels are needed to activate the large teleporter in the middle . The first is just to the right from where the Lone Wanderer first emerged from the airlock . The second is all the way across the ship , almost opposite the first . The third is very close to the central teleporter itself . Once all three panels are activated , step into the now - active transporter to end this quest and begin This Galaxy Ain ' t Big Enough . . .
