The Version 1.2 update for Zenless Zone Zero, titled 'Tour de Inferno,' launched on September 25, 2024, bringing a massive wave of new content to the urban fantasy action RPG. From powerful new Agents to sprawling story chapters and a host of quality-of-life improvements, the update aimed to expand the world of New Eridu and the Outer Ring. But what exactly did Tour de Inferno offer? For players who may have missed it or are looking back, here is a detailed breakdown.

Compensation and Update Details
To apologize for maintenance downtime, the development team offered two compensation packages: 300 Polychromes for the server update and another 300 Polychromes for issue fixes. Proxies who reached Inter-Knot Level 4 before the update went live were eligible. The server update compensation could be claimed until the end of Version 1.2, while the issue fix compensation was available until October 25, 2024. Players received these via in-game mail, which expired after 30 days.
Updating the game varied by platform: PC users needed to restart and select update; Android users followed in-game prompts; iOS users went to the App Store; and PS5 players checked for updates via the Options button.
New S-Rank Agents: Caesar and Burnice
The update introduced two limited S-Rank Agents. Caesar, a Defense-type Physical character, combines stunning and survivability. Her EX Special Attack activates Perfect Block when attacked, blocking damage and counterattacking with a shield that deals significant Physical DMG. She also provides shields and buffs for the entire squad. Caesar could be obtained via the Ember-Crowned Overlord channel.
Burnice, an Anomaly-type Fire character, excels at rapidly building Fire Anomaly through EX Special Attacks, which accumulate Heat. Once enough Heat is generated, she enters the Nitro-Fuel Cocktail state, applying Scorched to enemies. Her Fire DMG and Anomaly Buildup continue even when she is off-field. Burnice was available on a future channel.
New W-Engines and Bangboo
Two new S-Rank W-Engines arrived: Tusks of Fury (Defense) from the Dissonant Sonata channel, and Flamemaker Shaker (Anomaly) from a future channel. Additionally, a new S-Rank Bangboo, Red Moccus, could be obtained via the An Outstanding Partner channel.
Story Expansion: Chapter 4 and Blazewood
Chapter 4: Tour de Inferno became permanently available after the update, requiring completion of the special episode Undercover R&B. The story takes place in the wilderness far from the city, introducing new legends. A new area, Blazewood, located in the Outer Ring of New Eridu, serves as the main base for the Sons of Calydon.
Burnice's Agent Story, 'A Stroke of Luck,' unlocked on October 16, 2024, after completing Leisurely Lull: Unexpected New Customer. Agent Trust events were also added for Caesar, Burnice, Lucy, and Piper.
Events Galore
Version 1.2 hosted a plethora of time-limited events. The 'New Release' login event rewarded 10 Encrypted Master Tapes for logging in 7 days total. 'Overlord's Feast' ran from September 26 to November 4, offering a fiery feast for adventurers. 'Don't Walk Alone' (September 30 – October 14) introduced the Bizarre Brigade arcade game with exclusive rewards. 'En-Nah Into Your Lap' (October 16 – November 5) gave 10 Boopon for 7-day logins.
Other events included Data Bounty: Combat Simulation (double rewards), Ridu for You (puzzle collection), Roaming the Ether (Ether-themed journey), Advanced Bounty: Routine Cleanup (double rewards), 141 Friendship Fair (business plan), and Vicious Dogs Within (Godfinger rewards). A permanent HIA Investigator Training Course was also added.
System Updates and Optimizations
The update brought significant system changes. The Backup Battery Charge System allowed charge to recover beyond the maximum, up to 2,400, at a rate of 1 point every 18 minutes. Fairy-Auto Explore Mode let players send Fairy to explore commissions automatically, even offline. A city 'Character Select' function allowed free roaming with Belle, Wise, Caesar, or Burnice.
Hollow Zero received a Blitz mode for Withering Garden, allowing direct enemy attacks without Monitor Array exploration. The License Level cap increased from 60 to 90. Shiyu Defense added an Ambush Node with five frontiers and new Critical Node buffs.
Numerous quality-of-life improvements were implemented: new dynamic wallpapers, chat emojis, stat bonuses display, skill enhancement suggestions, new enemies, Swap Squads function, Preset Config, and controller optimizations. The game also added new achievements, adjusted weekly bounty commissions, and optimized various UI elements.
Shiyu Defense Adjustments
The Ambush Node became available, requiring completion of Chapter 2 Interlude: Mission Unthinkable and clearing Stable Node: Tenth Frontier. Critical Node buffs were updated for Phase I, II, and III, focusing on shields, Anomaly Buildup, and Burn/Shock effects.
Conclusion
Version 1.2 'Tour de Inferno' was a substantial update that expanded Zenless Zone Zero's world, characters, and systems. With new Agents, a gripping story chapter, diverse events, and countless optimizations, it offered both veteran and new players plenty to explore. Even in 2026, the content remains a notable milestone in the game's evolution.
