Dive into the heart of New Eridu with Chapter 2’s “Let’s Go, Bro!” in Zenless Zone Zero, where you’ll team up with Anton to navigate the treacherous Hollows, outsmart enemies by pushing Anton into battle, and unlock hidden treasures including the elusive Hollow Observation Data. This mission blends strategic puzzle-solving with intense combat, introducing you to the influential Belobog Industries faction and setting the stage for deeper mysteries ahead.
The gimmick for this level involves pushing Anton into enemies, allowing him to clear the enemies out. If Anton defeats enemies, they’ll drop coins. (If you manually fight the enemies, you won’t get this loot.)
Below we explain how to get all three Hollow Observation Data from the “Let’s Go, Bro!” investigation in Zenless Zone Zero, along with a complete walkthrough for the level.
’Let’s Go, Bro!’ objectives
The objectives of the “Let’s Go, Bro!” quest in Zenless Zone Zero’s Chapter 2 focus on entering the Hollow to locate a heavy-duty grappler, with optional goals of collecting up to three sets of Hollow Observation Data. Players must strategically navigate the area alongside Anton, using him to defeat enemies by pushing him into them, which helps clear the path and gather valuable loot. The mission culminates in combat against a mix of Machine and Ethereal enemies, including a challenging boss named Hans. Successfully completing these objectives rewards players with Polychrome, Investigator Logs, power supplies, and other valuable items, while also advancing the story and introducing the Belobog Industries faction.
- Collect 1 set of Hollow Observation Data
- Collect 2 sets of Hollow Observation Data
- Collect 3 sets of Hollow Observation Data
In this level, you’ll just need to collect the three golden orb icons to get all the rewards. For each piece of data you find, you’ll get 10 Polychrome.
One of the Hollow Observation Data in this level is locked behind a door and you can only get the coins to unlock it by having Anton take out some enemies for you. He just needs a little push!
ZZZ ’Let’s Go, Bro!’ walkthrough
The “Let’s Go, Bro!” quest in Chapter 2 of Zenless Zone Zero is a key story commission that introduces players to the Belobog Industries faction. The mission involves navigating the Hollow with the help of Anton, a trial character who can be pushed into enemies to defeat them and collect valuable loot. Players must strategically move Anton across enemy tiles to clear the path efficiently while collecting Hollow Observation Data for rewards. The quest culminates in a challenging combat encounter against Ethereal and Machine enemies, including a tough boss fight with Hans, requiring careful dodging and tactical play. Completing this commission grants various rewards such as Polychromes, Investigator Logs, and valuable crafting materials, making it an essential part of progressing through Chapter 2’s storyline.
You’ll see a straight path at first, so just go forward until you see this set-up:

- Go down twice, pushing Anton into the bottom middle enemy and grabbing Hollow Observation Data #1.
- Go left twice, forcing Anton to take on the bottom left enemy.
- Go down once and then up once, so Anton defeats the top left enemy.
- Go up once and then back down once, putting Anton back on the bottom row.
- Go right four times, making Anton take on the bottom right enemy.
- Mirroring what you did on the left side, go down once, pushing Anton up. Then go up again to force Anton to beat the last remaining enemy in the top right.
- Pick up all the gold coins before leaving through the newly opened path on the right. You should have 2,500 coins. (You technically only need to make Anton take out three of the five enemies, as you’ll only need 1,500 coins to unlock a door, but we’re being thorough here.)
You’ll fight a couple enemies in front of a broken brick wall before you squeeze through, leaving Anton behind. Head all the way down to reveal a new map.

- Go back up to meet up with Anton, though you’ll realize you can’t backtrack.
- Anton will now follow you down, mirroring your movement on the left side of the brick, so just run down so he takes out all those enemies. The enemies will drop silver coins, so go up and grab those once the path opens.
You’ll grab Hollow Observation Data #2 on your way out.

- Follow the path and head south to the locked door. Spend your hard-earned coins to open the door and grab Hollow Observation Data #3.
- Head forward on the path to the observation block on the left. More enemies and paths will be revealed.
Note that at this point, you have all three Hollow Observation Data and you don’t need Anton to beat the enemies for you. Pushing him into the enemies just saves you time, as you won’t have to jump into battle and deal with the enemies yourself.

- Go left twice, right once, down, and then left again to have Anton beat all four of these enemies.
- After all the enemies are defeated, the map will expand again.

- Collect the coins and set up Anton and yourself so you’re lined up in the middle, as shown above. It doesn’t matter if he’s on your left or right, as the results will be the same.
- Go down, initiating battle with one of the enemies. After beating them, push Anton right and left into the remaining enemies if you don’t want to battle them manually.
- Heal at the rest space and grab additional healing at the ether dewdrop spaces that appear, if you need it.
- Head toward the remaining enemy squares and take them out to finish this level.
