Mission Walkthrough

Examining The Water Purifier


Once the mission has started, you are to examine the Hyperion water purifier in front of you that has not been working for a long time.


Tannis will contact you using her siren abilities and examine the water purifier by phaselocking it to identify what the problem is but this won’t work for some reason.

Heading To The Secret Lab


After Tannis fails her attempt at fixing the water purifier she will instruct you to head to her secret lab to find a reason why the water purifier can’t be fixed as she thought it could.


Make your way towards the secret lab that is marked by the waypoint which you have already been to earlier on the Angels And Speed Demon’s mission.

Looking For Clues


Once you reach the secret lab, head over to the storage room where the clues will be located.


Head into the storage area and approach the painting of Handsome Jack which is actually a hidden passage deeper into the storage room.


Tannis will start talking about the painting and after a while you will be able to interact with it, moving it to the side.


After the painting is moved, there will be a button behind it which you need to press to open up the secret entrance.


Once the secret entrance is opened, you will need to follow Tannis’ instruction when she tells you what to examine one by one.

Examining Items


The first item that you will need to examine is a teddy bear that is sitting on the couch which will then bring back a memory of the child named Angel.


After examining the teddy bear, you are instructed to look for a vending machine which can be accessed after opening up a gate with a switch next to it.


The vending machine will be inside the room hidden to the left and your examine it which will bring another memory.


After the memory, a “Power Fuse” will pop out of the vending machine which you are to grab for using later.


Head over to a sealed area and insert the “Power Fuse” into the power box which will open up the way to finding the next item which is a Hyperion RKT Sentry.


Move into the area that recently opened and make your way towards the waypoint which will bring you to the upper floor.


There will be a power generator at the top that you should activate in order to supply power to the wires that are connected to it.


There will be a target connected to some wires which will allow electricity to flow through once you shoot it, provide power to another target with wires.


Shoot the target connected to the door in order to pass on the flow of electricity to it, opening up a small space where the Hyperion RKT Sentry is set up.


Interact with the sentry to once again begin another memory to play through which will reveal more about Angel’s past.


After the memory is finished, the sentry will begin to attack you violently and you must destroy it in order to proceed with the mission.


There will be a wood covering a passage on top of a ladder that you will need to destroy in order to access the next area where Tannis has instructed you to find a satellite.


Head up to the satellite and interact with it to play another memory which will conclude what happened to Angel as well as give Tannis enough memories to finally fix the water purifier.

Back To Roland’s Rest


Fast travel back to Roland’s Rest and head towards the Hyperion water purifier for another attempt to fix it.


Tannis will use her siren abilities to phaselock the water purifier again but this time it will be successful and she will tell you to go inform Vaughn that the water purifier is working again.


Childhood’s End Mission Rewards


When the Childhood’s End mission has been finished, you will be rewarded with around 12,671 cash and the “Loop of 4N631” rare shield mod.



  • There won’t be much combat in this mission unless you decide to face the enemies along the ways which you should probably ignore if you are levels higher than them.
  • Fast travelling around can save you a lot of time getting from one place to another.
  • Rushing through the enemies and heading towards the waypoints can help speed the mission up.
