Complete walkthrough for the 'Taking Flight' main mission in Borderlands 3. Includes steps for defending Tannis, collecting biofuel, and retrieving the Astronav Chip.

Walkthrough
  1. 1
    Go to Eridian dig site: Head northeast of Ellie’s Scrapyard. Find the Typhon Log in the Skag den to the right of the entrance if you haven't already. Speak to Tannis inside her residence, then loot the surrounding area while you wait for her analysis.
  2. 2
    Defend Tannis and the map: The Calypso Twins will send COV enemies from the north. Stay near Tannis and use cover. After the initial wave, Lilith will arrive, making the defense easier. Tannis will then examine a map pointing to Promethea.
  3. 3
    Head to ship in Raiders’ Drydock: After looting the dig site, go northwest to Raider’s Drydock. Before heading to Ellie, find an Echo Log to the left of her.
  4. 4
    Collect biofuel (by running over stuff) [10]: Use the Biofuel Rig vehicle to mow down COVs and Skags. Follow the waypoints, which lead to clusters of enemies.
  5. 5
    Get astronav chip: Travel to the far northwest corner of the map, in Dahl Orbital Control. You won't be able to reach the area directly; instead, follow the wall west to find a cave. Leave the Biofuel Rig outside and go inside to find stairs. A large group of COVs will attack as you approach the Astronav Chip. Use cover and the environmental hazards (electrical radiator, barrels) against them. After the fight, grab the chip.
  6. 6
    Find Typhon Log and White Chest: Before leaving the area, exit to the cliffs northeast of the cave to find another Typhon Log. This may unlock a Dead Drop west of your location. To the right of the log, find a White Chest and a route back to the Biofuel Rig. Return to Ellie with the Biofuel and Astronav Chip.
  7. 7
    Fight to Raider’s Drydock via catwalks: Head back towards the Drydock. Go behind yourself and up towards the catwalks to reach Lilith. Dispatch COVs along the way to the elevator and then more as you head to the Drydocks. Take your time to recover shields if needed. Drop down at the end, grab ammo from containers, and proceed to aid Lilith.
  8. 8
    Kill COV attacking Lilith: In a large open area, fend off COVs attacking Lilith. Use cover and prioritize any Badass enemies that spawn.
  9. 9
    Complete Mission: Revive Lilith, then head to Ellie to complete the mission.
Tips
  • Use the radar effectively to spot enemy attack directions.
  • Utilize your Action Skill frequently, especially before Lilith arrives.
  • Skags are the easiest targets for the Biofuel Rig.
  • Make use of environmental hazards like electrical radiators and barrels during the Astronav Chip retrieval.
  • Don't rush the catwalk section; recover shields if necessary.
  • Focus on Badass enemies during the final fight to make it easier.
