Zenless Zone Zero has a reputation for its high-octane combat, and HoYoverse will once again leave players on the edge of their seats with the new combat events. Every patch in ZZZ brings a bunch of combat events that get players gearing up for some action, and, of course, Polychromes! Version 2.6’s main event, A Harmony of Delusions, is here, along with the second iteration of Threshold Simulation: Myriad Endgame. Unlike the smaller, quick-clear side events, these two are long-haul challenges that stretch across weeks, and they're here for a reason. Here’s what you need to know about the new Zenless Zone Zero 2.6 combat events.
ZZZ 2.6 Combat event: A Harmony of Delusions
A Harmony Delusions is the flagship event for version 2.6, and it’s split into three major parts: Shining Melody and Solo Note, Performance Showdown, and Grand Marcel Adventure.
A Harmony Delusions event overview:
| Duration | February 06, 2026 11:00 GMT+8 to 23 March, 2026 03:59 (Server Time) |
| Type | In-game, Flagship event |
A Harmony of Delusions is a month-and-a-half-long event where players train with the Angels of Delusion idol group and manage their social media accounts to boost engagement and earn Starpoints. Throughout the event, players can enjoy rhythm stages, combat challenges, and the Grand Marcel Adventure maps. Various rewards are up for grabs, including an event-exclusive outfit, special currencies, titles, a Hamster Cage Pass, Polychromes, and chips.
When the event wraps up, it doesn’t leave the game for good. Players will still be able to access it in the following patch, allowing them to jump back in and play through the content whenever they like through the Ridu Chronicles.
How to Participate in ZZZ 2.6 A Harmony Delusions Event
The new flagship event only comes with a couple of simple requirements: Proxies need to reach Inter-Knot Level 20 and complete Chapter 1 – Intermission of the Phaethon’s Story. After that, the event becomes fully accessible, allowing players to jump straight into the limited-time content and start clearing its challenges and rewards.
Shining note and solo mode
The Angels of Delusion are performing in hopes of becoming New Eridu’s Rising Star, and as their manager, one of the hurdles to overcome is the rhythm game. Shining Note and Solo Mode follow the basics of a classic rhythm game: press the right key at the right time to win. Players can also choose from the members of the Angels of Delusion for the center position to take advantage of their special performance skills.
Much like in other modes, Hard Mode unlocks after completing Easy Mode.
Rewards:
- 200 Polychromes, 15× Senior Investigator Log, 100,000 Dennies
- 300 Polychromes, 60,000 Dennies
Performance Showdown mode
Performance Showdown has the mix of combat and rhythm games, but instead of just notes, you’ll time your parries and dodges. When the bar shows a red arrow, dodge and if it’s yellow, parry the attack.
Rewards:
- 300x Polychromes, 600,000 dennies
Grand Marcel Adventure Mechanics
The final part of the event is the Grand Marcel Adventure Mechanics, an event which just came back for the second time. If you’re into Fall Guys type of games, this is for you. Instead of agents in the game, you’ll play as Eous and you’ll be pit into different Grand Marcel Adventure maps filled with obstacles. It’s a coop event, so you can also queue up and play with friends or random players.
There are twelve maps available, and the goal is to either race against other players or survive.
By participating in the event, you can also get limited-edition Eous outfits by exchanging Marcel Coating Vouchers.
Rewards:
- 300x Polychromes
- 30x Original chip
- 5x W-engine Energy Module
- 70,000 dennies
All Harmony Delusions Event rewards
Harmony of Delusions is a flagship event packed with valuable rewards for those who complete it, here's everything you can get from it.
Free Pan Yinhu Outfit – Culinary Jewel
In Version 2.6, Pan Yinhu receives his first free outfit. Clear the “Glimmer! Blossoming? Echoes of the Wild Dreams!” event quest to claim it.
Horsehead New Accessories
It’s the Year of the Horse! To celebrate, ZZZ is giving out free Horsehead accessories that Agents can equip. Players can obtain them by farming 2,000 Popularity Carrots from the Grand Marcel Adventure stage.
Threshold Simulation: Myriad Endgame
In version 2.6, Zenless Zone Zero is welcoming the new Threshold Simulation update. This game mode was first introduced back in Version 2.3, split into two parts: a permanent easy mode and a rotating hard mode. Besides the new set of enemies, buffs, and conditions, new changes have been implemented. In this mode, the combat nodes are reduced from four to three, while story nodes went down from three to two. The interface was also adjusted for a better experience.
How to Unlock Threshold Simulation: Myriad Endgame
Threshold Simulation is a game mode that players can unlock after reaching Inter-Knot Level 55, and progressing through the beginning of Chapter 2 of the Main Story. Once you unlock the game mode, Threshold Simulation: Myriad Endgame or the Hard Mode will open after completing the easy mode.
How to Play Threshold Simulation: Myriad Endgame
Threshold Simulation is a game system that’s perfect for both loreheads and players who enjoy combat. Threshold Simulation: Myriad Endgame is the Hard Mode of the game.
In this mode, players will need up to five unique teams and Bangboos. There are different types of stages per battle: Required Stage, Optional Stage, and Final Stage.
It’s important for players to plan ahead before jumping into this mode, as choosing the best and most optimal team for each stage can mean the difference between winning and losing a battle.
Each stage mixes things up with different enemies, each with its own weaknesses and resistances. There are also stage-specific buffs that can completely change how a run plays out. Swapping units around and adjusting the game plan helps a lot, especially when you don't have a well-built team. Don't worry though, as you can get to experience and try free agents in the rotation!
Here's a total of rewards that you can get from Threshold Simulation: Myriad Endgame:
| Polychrome | 500 |
| Denny | 275,000 |
| Original Chip | 24 |
| Hi-Fi Master Copy | 6 |
| Tuning Calibrator | 1 |
That’s everything you need to know about all the Zenless Zone Zero Version 2.6 combat events. A Harmony of Delusions and Threshold Simulation are not only good sources of Polychromes, materials, and limited-edition rewards, but they are also a great way to test your skills and reaction time. Claim the rewards from these events, and don’t forget to treat yourself to some cheap and affordable Monochromes.
