Zenless Zone Zero — Trail to the Source Walkthrough

Proceed to complete the order. Move left, collect the Elite Explorer's supply crate and stand at the endpoint on the left. Contact Grace, move left and stand on the cage with the magnifying glass. Follow up the new area by taking the observation data.

After that you need to drive the tunneling machine without hitting the bombs:

1. 4 times up
2. 4 times to the right
3. Once up and to the right to take the senior researcher's supply crate
4. After that, step left, down and stand on the four blue squares on the right.

Move to the opposite side where a passage has opened up. Pick up the second observation data pack and stand behind the control panel of the second machine. Move the grader, which can destroy bombs. Clear the area, make sure to take the crate of the senior researcher and finish off the enemies. On the way back to the objective you will have to destroy the enemies.

Move through the portal to a new location. Move down to the left to pick up the third surveillance data pack. Move up first to find the ether drops, heal yourself and pick up the Elite Explorer's supply crate. Continue to the indicated point on the upper left to start the final battle.

The enemy has a lot of unblockable attacks, so watch out for the red flash. He can also throw different objects with his long tail: look under your feet, the places where they fall are highlighted in red. You should also win the second stage of the battle, but when the boss regenerates health points for the third time, don't be in a hurry. Keep fighting. The health bar won't decrease, but soon a cutscene will start up and Kolyada will help you out. Watch the epic cutscene that concludes the order.
