Operation Cleaner, Part 1 in ZZZ - Walkthrough

Follow the soldier, go down, break the boxes to collect the Denny. Ethereals will appear soon. Destroy the enemies, talk to Eos and agree to continue the journey.

Destroy the enemies, go to the marked terminal and turn off the laser beams. Go to the soldier ahead. There is a mini-truck to the left of him. Go back out into the hall and go to the marked door. A soldier will run up to you, who will knock down this door (you don't need to do anything, just wait).

Continue moving along the corridor and clear the room. Kill the enemies in the next corridor. Talk to the soldier ahead, go down the steps, collect the supplies on the left, go down and talk to the soldier in front of the door.

The soldier should knock down the door. Go through it and defeat the Elite Ethereal. Interact with the terminal on the left to disable the laser beams. There is a mini-truck hidden behind the stands on the right side. Don't rush down the stairs. Turn into the room on the left, enter the rift to start the challenge. For completing it, you can open the mini-truck. You need to survive 5 enemy waves in the allotted time.

Go down below and defeat the enemies. Interact with the terminal to disable the laser beams. In the room on the right side, look for the fourth mini-truck. Follow the marker, collect supplies and fight the ballerina. After victory, go to Eos to complete the task.
