Discovery: Takedown at the Maliwan Blacksite is an optional mission given by Lorelei from a device aboard Sanctuary III following the completion of Borderlands 3, added as part of the free Takedown at the Maliwan Blacksite DLC.
- "Lorelei has identified a Maliwan target of opportunity."
- Navigate to Midnight's Cairn
- Use drop pod
After completing the main story, a device aboard Sanctuary III will become active, located beside a crate to the left of the entrance to Marcus's store. Accepting the mission provided by it, Lorelei will inform the Vault Hunters of intel she discovered regarding a Maliwan research facility developing new weapons, which would be extremely problematic for the war on Promethea should the weapons be deployed, and tasks the Vault Hunters to travel to the facility and "knock some sense into 'em".
Like other discovery missions throughout the game, the player must navigate to Midnight's Cairn from the bridge of Sanctuary III. Upon arriving, the player must use the drop pod found in the cargo bay to reach the planet's surface. After reaching the planet, the mission will be completed, and the next mission, Takedown at the Maliwan Blacksite, will automatically begin.
- "Wicked! Get in there and take down whatever Maliwan's cookin' up. I don't care how you do it, as long as it's messy."
