Now you’ll need to follow clues that lead to finding 4 switches located in Caustic Caverns.

>> In sawtooth Cauldron, Vault Hunter finds an ECHO recorder

Creepy Bandit: They’ll never find it. Never find my treasure.
Was in Old Haven. Not anymore. Mine. Scatter the map. Give it to bandits.
Nobody will ever find it. NEVER!

>> Mission objectives update: Collect clues 0/4

Brick: Woah. Sounds like that dude was talkin’ about the lost bandit treasure of Old Haven.
If you find the pieces of the map, you could be the first person to dig it up.
Sounds like bandits have the map pieces, but there’s no way to know which ones got it — just keep killin’ bandits and hope for the best! Hahahaha.

>> Vault Hunter keeps killing bandits until they drop the first clue.

Brick: Long time ago, there were these guys — the Crimson Lance. Worked for the Atlas Corporation.
They tried to kill us. It was pretty funny. That treasure you’re searching for belonged to the last of ’em.

>> Vault Hunter picks up the second clue.

Brick: After we killed their general, the remaining Lance either joined us in New Haven or went rogue.
The rogue ones set up shop in Old Haven, robbin’ and murderin’ anyone within a turd’s throw of their little city.

>> Vault Hunter picks up the third clue.

Brick: After a few weeks, Roland and Lilith headed to Old Haven and wiped the rest of the Lance out.
The Lancemen kept sayin’ somethin’ about a treasure of stolen loot they’d stashed somewhere.

>> Vault Hunter picks up the fourth clue.

Brick: You got all the map pieces, huh? Looks like you should go to the Caustic Caverns and follow the clues.
Everything goes well, you’ll be one rich Slab.

>> Mission objectives update:
Follow clues
Under the acid-soaked railway
In the warehouse on the shore
In the digger’s shadow
Within Dahl’s bloody sixth
