How to Investigate the City Wall in Borderlands 4

After leaving Moxxi’s Bottoms Up, travel to the central area of Lopside in Carcadia Burn. You’ll see a purple trail of Eridium on your map leading east – follow it into Siltgrasp Canyon. Continue forward, using the grapple point to progress, and you’ll eventually find a piece of Callis’ ship that crashed during the previous mission. Inside the ship, press the red button near the east door to open it, which will lead you into the Carcadia District of Dominion City.
