Zenless Zone Zero: Full Chapters & Mission List

Zenless Zone Zero is chock full of chapters and missions for players to work through, including its main story and a plethora of side quests.

Zenless Zone Zero is an unsurprisingly long game. Coming from the same developers behind the eternally long Genshin Impact, it’s clear that ZZZ will have players hooked for a long time. However, right now, it’s possible to get through its content in a reasonable length of time. But how many chapters and missions are there to get through before you reach the end credits? Here’s what you need to know.

All Chapters in Zenless Zone Zero

There are currently three chapters in Zenless Zone Zero’s main story, known as Phaethon’s Story. These chapters are split up into Parts and Interludes, each with their own sets of missions. In total, the three chapters are split into 11 different Parts.

In addition to the main chapters, players also have access to Agent Stories. These serve as the game’s side missions and aren’t connected to the main story. Finally, all of the main missions and side quests can be replayed via the Video Archive in the Random Play store location. You can replay missions from both Phaethon’s Story and Agent Stories.

How Long to Beat Zenless Zone Zero

It will take you 50 hours to beat all of the main and side content currently available in Zenless Zone Zero. This includes the Phaethon’s Story and Agent Stories missions, as well as a small amount of grinding. However, you could easily extend that runtime to 70 to 80 hours if you grind the endgame content and multiplayer minigames with your friends.

Of course, as Zenless Zone Zero is a live service game, additional content and missions will be added in the future. As a result, we can expect the runtime to exceed over 100 hours in the near future. For now, players can catch up with the currently available content in not too long a timeframe. That’s everything you need to know about Zenless Zone Zero’s chapters and missions. For more guides just like this one, be sure to check out our Guide Hub.
