Zenless Zone Zero has collectible models that can be found in the cavern. To successfully complete this task, it is recommended to form a squad that includes characters with ice and ethereal attributes. This will help deal with the opponents encountered in the cavern.

To find a missing amplifier box, follow these steps:

1. Move right to the red switch button. Open a new part of the playing field and walk along the rails that appear to avoid meeting the enemy. Take the purple supply box.
2. Move right to the magnifying glass icon to unlock a new area. Make your way up to the enemy and fight the five Turfings to end the battle.
3. If you have lost a lot of health in battle, you can visit the rest area cell on the left to restore your health. Then move right to the red button that opens a new path.
4. Move right to a cell with a gray block. Along the way, you can collect the first observation data from the orange cell. Open a new part of the field, move directly to the cell with the obstacle and move it. Go around the block above or below and pick up the purple supply box. The green reset button will return the gray block to its place if you push it incorrectly.
5. Move left towards the barrier and move it. Position the gray block so that it is below the blue button. Go around the cell below and push the block up, right onto the button.
6. Move down to the rail and enter the new field area to pick up a golden supply box. Before pressing the button, go around the cells with images of denny and the cells with observation data.
7. In the center of the field, take the required amplifier. Click on the red switch button at the bottom.
8. Walk along the rails that appear and enter the cell with the flag to complete the race. Before leaving the test, you will have to fight a squad of alraun and two tyrfings.
