Ratch’d Up is a side mission that will be available towards the end of the Promethea story.
The mission is to help Rhys find out what happened to his janitor who went missing.
This is a brief walkthrough of Ratch’d Up in Borderlands 3.
Recommended level: 17 and above.
Your first objective is to look for Terry, the guy who went missing. Go upstairs from the Atlas HQ.
Follow the marker to the janitor’s room.
Search for clues
Inside the room, you need to press the green button hidden behind the pot.
It will unlock a hidden door.
In the next area, go towards the red door to proceed.
You’ll then hear a voice. Investigate the voice by heading to this red door that is locked. You will be introduced to Glenn.
Open Glenn’s cell
You need to open Glenn’s cell (red door) but the switch is behind the glass.
Follow the route that leads a long way around.
Eliminate ratch threat
Once you’re in the room where the switch is, eliminate the ratch threat first.
Press the switch when the area is secure.
Talk to Glenn
Speak with Glenn who was actually turned into a ratch by Terry.
Pick up Terry’s brain
As Terry’s dead body is on the floor, Glenn attempts to transform Terry into a ratch.
Pick Terry’s brain up.
Lower the cage
There’s a cage in the middle with a big creature inside.
Lower it using the switch.
Kill the creature named Gary who came out from the cage.
Place Terry’s brain
Go down to where the cage is. Place Terry’s brain on the console to start the process.
Talk to Glenn
Once Terry’s been transformed into a ratch, head back to Glenn and speak with him.
The mission ends here.
