We already knew about Astra Yao possibly being a future playable Agent, whoever latest leaks reveal another character that may be playable in the near future!
Not long ago leaks had revealed that Astra Yao, the famous singer you can see in some places such as  Lumina Square in New Eridu, would be playable in the near future (1.5).
Another character seems to make her appearance at the same time as Astra Yao: 
Her name is Evelyn, and nothing is known about her so far. It is not a character we have seen previously in the game. 
According to the leaks, you will be able to talk to both Yao and Evelyn in the new game Hollow Zero - Lost Land game mode.

Players are trying to guess if Evelyn will be part of the same faction as Yao, if she may be something like her manager. Others think she may be another member of the Criminal Investigation Special Response Team, or part of Soldier 11's Obols Squad! 
We will of course update you as soon as more information is shared about those two future Agents!

Version 1.4 of Zenless Zone Zero will come with a new Hollow Zero mode. Latest leaks have revealed some information about it, here is what you need to know!
New information has been found through leaks about the version 1.4 New Hollow Zero mode: Lost Land.
We already know that this mode will give you access to Agent specific Resonium that will modify their gameplay, however, not much was known about the mode itself.
Latest leaks have revealed more information about the Lost Land mode:
It seems that the Hollow Zero - Lost Land will be similar to Honkai Star Rail's Simulated Universe. For players who are not familiar with Honkai Star Rail, the Simulated Universe is a rogue-like combat challenge where you navigate through different "worlds" with unique challenges, bosses, and where you can collect various blessings that will buff or debuff you during your run.
Hollow Zero - Lost Land seems to follow the same idea: no Tv's, only areas where you will get various buffs or debuffs during your run, and you will have to defeat different bosses or enemies. The final boss seems to be Nineveh again, hinting at a rather hard challenge. Some resonias are not categorized, such as:
Overclocked Boundary Mode: Significantly increases damage (20% Attack and Crit Dmg boost), but ends if hit even once (even with a shield). Blood Reaping Mark: In battle, reduces max health by 30% for N rounds. Stalwart Enemy mark: Monsters recover from the Daze state faster in battle for N rounds. The fact that Nineveh is again the final boss seems to get a negative reaction from most players.The boss is rather annoying with a long invincibility phase and the projectiles that can knock down your characters while you try to kill the adds. We can maybe expect other bosses to be added in the future, that will most likely replace Nineveh in this mode.

Zenless Zone Zero 1.4 leaks are showcasing Enemy bas HP and Base Max Daze increase! Here is what you should know about it!
Leaks shared by Leifa have shown that for version 1.4 of Zenless Zone Zero we will see Enemies' Base HP and Base Max Daze increase:
A lot of enemies will have their Base HP and Base max Daze increased due to Ultimate changes. Enemy Hp appears to have increased between 6 to 14%, while Daze seems to have increased between 20 and 27,5%.
The Daze increase may signify a big change, as it will maybe force players to use ultimates such as Caesar's who does double Daze to Shielded enemies, instead of automatically keeping the ultimate for the DPS agent. 

Exciting new leaks have surfaced, showcasing gameplay animations for upcoming characters Asaba Harumasa and Hoshimi Miyabi in Zenless Zone Zero.
The well-known leaker Dimbreath recently posted these previews on social media which then spread to the ZenlessZoneZeroLeaks subreddit.
Asaba Harumasa’s animations video is short due to the character still being a work in progress in the current beta. Harumasa has only a few animations at this stage, meaning that there is more development to come before his official release. 
In contrast, Miyabi’s animations appear more polished, and honestly look incredible. The attacks appear to have a wide attack range with beautiful animations, she's sure to be a worthwhile pull just for aesthetics but is also seeming like a powerhouse of a character. The reddit embed may not be fully functioning so a repost of the video on youtube has been embedded below too.
 

Latest Leaks are revealing interesting information about the new upcoming Hollow Zero mode: Specific Resonium for some Agents!
The Hollow Zero in Zenless Zone Zero will receive a new mode soon called Hollow Zero - Lost Land. This mode seems to be some sort of rogue-like Hollow Zero mode, similar to the Elysian Realm from Honkai Impact 3rd. 
In this mode, some Agents will have Resonium that will change their gameplay when played in this Hollow Zero mode. The latest leaks from Seele are showcasing 4 resonium for Ellen Joe:
From left to right :
[Ellen] Frost Blade During the third phase of the [Basic Attack: Flash Freeze Trimming ], gains super armor and -75% damage reduction. At the end, it triggers a [Qi Sword Attack], hitting all affected enemies . [Ellen] Menacing bearings While in the [Roaming ] state, Ellen can charge and obtain [Quick charge]. When [Flash Freeze Charge] or [Charged Scissors] hit an enemy, each charge level leaves behind a patch of ice mist .

When any character in the team consumes Decibels Points, it also adds energy to the Resonance Cloth. When the Resonance Cloth is fully charged. Other characters that will most likely get some resoniums are Billy, Miyabi, and Yanagi. It is unknown whether all agents will receive specific resonium for this mode or not, but this information is rather huge, and makes the new Hollow Zero mode very interesting!
