Promethea is the second planet you go to in Borderlands 3. While you are here you will run into a few side quests you will have to complete. Check out this Borderlands 3 Promethea side quest guide to complete them all as you go along.
Borderlands 3 Promethea Side Quest GuideYou will start getting side quests pretty early in this area.
You need to head back to the Meridian Outskirts and the blue barrier that normally blocks this place is now open. Kill the enemies inside the base and then speak with the scientist. He will give you a vehicle so you can capture some creatures for him. Get three of them and return to his lab. You will have another fight on your hands, and a big one to boot. When the bad guys are done, the quest is complete.
You have to enter Lectra city and kill 3 targets. This quest sucks because this zone is rough and you can’t drive. While you are killing the targets, Moxxi will tell you to get some batteries for her as well. The targets are easy to find, but hard to kill. The batteries can be a bit more tricky. One is found here on the map.
The next one is found here on the map. You have to jump up in a tight alley way here.
Jump up this part and turn around to see a ladder. Get a running jump to that ladder and climb up to the battery.
Third one is easy, just don’t fall into the water.
You can get down to the subway here if you get lost.
