Hollow Deep Dive System Events and Guide
Use the cannons to shoot the enemies using D Rounds. This will unlock a warp on the position of the top enemy. Go inside the warp to access the next map and don't forget to grab the Elite Investigator Supply Box along the way.
Similar to the first map, you'll have to use the cannons to shoot D Rounds against enemies to prevent them from going inside the two fissures which are portals to the drill rig.
However, there are 6 rows where enemies will spawn making this a harder challenge than the previous map. Defeated enemies also give you Gear Coins that you can use.
If enemies go inside the fissure and damage the drill rig 12 times, you will have to retry this part of the commission although, you get to keep the Gear Coins that you earned in the previous attempt.
After finishing the first wave, an engineering device will spawn down the map which can unlock two launch buttons for 1500 Gear Coins.
Launch buttons will allow you to use DDD Rounds which can eliminate enemies in a row.
It is highly recommended to unlock buttons each time you get enough coins as waves get harder.
During later waves, there will be points where some enemies will be next to each other as they approach near the fissure.
Use the Launch Buttons that you unlocked to attack the whole row where the launch button is positioned to eliminate all enemies currently in that row.
Note that once you press a launch button, they will be unusable and you will need to reset them on the engineering device by paying 1500 Gear Coins if you want to use them again.
Purchasing and unlocking all the launch buttons for all the cannons will help you obtain the Firework Show Achievement.
After you survive the 9 waves, go to the top of the drill rig to initiate a battle. After completing the battle, go right and this will unlock the final map where you can obtain three observation data and two Senior Supply Boxes.
Note that you can only get two senior supply boxes when you cleared all Golden Bangboos and the Drill Rig didn't get damaged even once.
After getting all the items in the area, exit the map to complete the commission.

I left out something important, on that attempt I also managed to clear all the Golden Bangboos. I highly assume this is the definite reason the Senior supply box appeared.
