Sanctuary | Borderlands 3 Walkthrough Borderlands 3 guide, walkthrough
Last update: 19 September 2019
This page of the guide to Borderlands 3 has a walkthrough for Sanctuary, one of the main missions. This mission serve as something like a tutorial for traveling the world in the Sanctuary spaceship. You will meet some important people on board the Sanctuary. Also, some members of its crew will ask you to solve their problems.
There are stairs near the place where you have started the quest. Go up. Use the next (metal) stairs and get to the back entrance to get on board the Sanctuary spaceship. Heroes leave the planet Pandora - the ship is now in orbit.
You can use fast travel to go back to Pandora later in the game. You don't have to do everything before you leave the planet.
Start by talking to Lilith. Go to the central console and place the Astronav Chip. Once the situation calms down, you will get 3 new mission objectives. You can deal with them in any order.
Our walkthrough contains only the steps necessary to accomplish this quest. The Sanctuary has many optional activities. We recommend that you carefully examine all levels and all cabins of the ship.
Tannis is in the Infirmary. Go to the temperature control device and use a melee attack on it. Wait for Tannis and talk to her.
You have to help Marcus put out the fire in his shop. Hit the fire extinguishers, which may be on the ceiling or wall. This will put out the fire in three different places.
Talk to Marcus, and go to the SDU station. You can buy improvements that increase the inventory capacity. We recommend that you purchase upgrades for your total inventory capacity and those increasing ammunition limit for your most commonly used weapons. More information about that on How to increase inventory capacity? page.
Another place to visit is the Crew Quarters. One of the cabins is closed - you learn that there are several people imprisoned inside. Find the lever and pull it.
This cabin will become your own. Here, you can find a storage chest in which you can store unnecessary items.
Go to the lower board to meet with Ellie. Pull the lever on the glass wall fragment to open the door to the vacuum and, by sucking the oxygen out, you will extinguish the fire.
Go down to the lower level and get to the storage room - you will find Crazy Earl. Knock on the door to talk to him.
Head now to Moxxi's nightclub located on the opposite side of the ship from Marcus's shop (use any stairs to leading to the upper levels). Talk to Moxxi and go to one of the slot machines. Pull the lever and get the prize - Eridium.
Go back to Crazy Earl. From now on, you can buy cosmetic items from him, although this is not required to complete this quest.
Regardless of whether you made a purchase or not, Earl will throw Entropy Accelerator out of storage. Pick it up.
Go with the Accelerator to the specified location on one of the higher decks (the picture above). You have to install it. Return to the captain's bridge.
Interact with the ship's navigation system and select Promethea as a destination. After reaching its orbit, talk with Lilith - this will complete the quest. You unlock a new main mission - Hostile Takeover.
