2 Kill Sludgemaw
3 Talk to Rhodes

Escort the Implosion Drive

# Walkthrough
1
Borderlands 4 Push Implosion Drive
Get up to the structure behind Rhodes and perform a melee attack to push the implosion drive onto the loader.
2
Borderlands 4 Watershed Gate Location
Head north to Watershed Gate to meet the Outbounders. Help them defeat the Order guards in the area.
3 Once it's clear, talk to Rhodes and he’ll ask you to open the loading bay. Interact with the door panel to let ECHO-4 hack in. Defend yourself while your drone hacks the door!
4
Borderlands 4 Elevator Switch
After opening the loading bay, escort the implosion drive inside the hydroplant while dealing with enemies along the way. Interact with the switch on the left to open the elevator.
5 Continue escorting the implosion drive to the roof until it enters a doorway along with Rhodes and Conway. Be careful, as you will encounter more enemies.
6
Borderlands 4 Reservoir Controls
Take the stairs to reach the hydroplant reservoir. Interact with the nearby valve to drain the water, then flip the switch across the other side to release the loader.
7
Borderlands 4 Lower Loader
Escort the implosion drive and flip the switch on the platform where the loader stops. You’ll then be attacked by drones. Destroy them to proceed!
8
Borderlands 4 Control Room Reactor
Enter reactor maintenance in the northwest. Go to the control room at the far end and interact with the computer to raise the reactor.
9
Borderlands 4 Reactor Components
Rush will then ask you to look for three reactor components. The first two are on opposite sides of the hall near crates, while the third one is in the room upstairs on the right.
10
Borderlands 4 Install Reactor Components
Install the components in the reactor at the center. Return to the control room and press the button to lower the reactor.
11 Head back outside to the implosion drive and flip the switch again to lower the loader along with yourself.
12
Borderlands 4 Unload Implosion Drive
Escort the implosion drive until it parks on the platform in the northwest. Unload it once it’s parked.

Kill Sludgemaw

# Walkthrough
1
Borderlands 4 Activate Reactor
Go to the control room in the upper left and activate the reactor. Defend the implosion drive and defeat all enemies!
2
Borderlands 4 Eject Implosion Drive
Once it’s clear, press the button behind the implosion drive to eject it down below. Before jumping down, use the vending machines nearby to prepare for an upcoming boss fight.
3
Borderlands 4 Sludgemaw Boss Fight
When you're ready, jump down the hole and follow the implosion drive into a cave. This leads to a boss fight against Sludgemaw. Defeat the boss!

Sludgemaw burrows and surprise attacks, so dodge as soon as it pops out from the ground.
* Borderlands 4 Sludgemaw Crate
You can stand on the crate behind the implosion drive to cheese the boss fight. Since Sludgemaw only moves on the ground, it can’t reach you while you're on the crate, though it can still shoot projectiles at you.

Talk to Rhodes

# Walkthrough
1 After defeating Sludgemaw, inspect the implosion drive.
2
Borderlands 4 Talk to Rhodes
Leave the lower-lower level and talk to Rhodes. This will complete the mission.
