Zenless Zone Zero

Zenless Zone Zero (ZZZ) is a free-to-play action role-playing game developed and published by miHoYo (with publishing outside mainland China under Cognosphere, d/b/a HoYoverse). The game was released on Windows, iOS, Android and PlayStation 5 on July 4, 2024.
A port for the Xbox Series X/S is in development.
Zenless Zone Zero is an action role-playing game. The player assumes the role of a Proxy (the protagonist known as Belle or Wise), a character who helps others explore alternate dimensions called Hollows. Over time, the Proxy will recruit new party members known as Agents to fight hostile entities called Ethereals and other enemies. In addition to the Proxy, players use rabbit-like robotic assistants known as Bangboos.
The gameplay is split into two different modes: "TV Mode" and "Combat Mode." TV Mode gameplay resembles a 2D dungeon crawler game, with the Proxy roaming on tiles that resemble televisions to find treasure, solve puzzles and fight enemies. If the Proxy steps on an enemy tile, the party is sent to "Combat Mode," where they fight in a 3D hack and slash-like game mode.
By combining the abilities of different Agents and Bangboos, players can deal greater damage and combos (known as Chain Attack) onto enemies. The game features an in-game clock system, with the days split into morning, afternoon, evening, and midnight.
The game takes place in a post-apocalyptic futuristic haven known as New Eridu. Large pocket dimensions called Hollows plague the world, engulfing the land and spawning hostile monsters called Ethereals, who have wreaked havoc on humanity. After the fall of Eridu, a group of survivors established a bastion against the invaders known as New Eridu. The group survived the oncoming onslaught by extracting a substance called Ether from the Hollows, which is used as a potent energy source for the entirety of New Eridu.
Several factions are present in the game. The Cunning Hares, formally known as Gentle House, is an “odd jobs” agency from which the player obtains their first three agents. Belobog Heavy Industries and Victoria Housekeeping Co. specialize in construction and housekeeping, respectively. Hollow Special Operations Section 6 is a frontline unit of Hollow Special Operations, which is based in the original Eridu location. The Criminal Investigation Special Response Team is a branch of New Eridu Public Security. The Sons of Calydon is a biker gang. Lastly, the Stars of Lyra are a famous music group based in New Eridu.
The story follows Belle and Wise, two siblings who are proxies and are secretly the legendary Phaethon. The siblings possess a special technology known as the Hollow Deep Dive System, which allows them to remotely monitor and navigate Agents within Hollows through the use of their Bangboo, Eous. As the player progresses through the game, their proxying capabilities are expanded with the addition of the A.I. Fairy, who can analyze Hollows.
Despite falling into the "futuristic" category, Zenless Zone Zero adopts a retro and analog aesthetic, which is explained by the notion that modern technology is susceptible to corruption from overexposure to Ether. Characters operate flip-phones or mobile phones reminiscent of models from the 2000s and 2010s. The two main protagonists reside in a video store (known as Random Play), where New Eridu citizens can rent VHS tapes. CRT television sets reminiscent of those from the early 1980s and 1990s are commonly seen throughout the game. There are also references to 1990s media as well as grunge or street-style designs present throughout New Eridu.
The player takes the role of the "Proxy", Belle or Wise (depending on the player's choice), one half of a sibling duo who are collectively known as the legendary "Phaethon". They operate a video rental shop called "Random Play" as a front for their undercover activities as Proxies; individuals who assist Hollow-raiding Agents in navigating the hazardous and ever-changing landscape of Hollows. To this end, Phaethon utilizes a Hollow Deep Dive System, or HDD, which allows them to project their consciousness in real-time into a small rabbit-like robot called a Bangboo, as opposed to other publicly-available Hollow observation systems which have a significant time delay on information going to and from a Hollow. As being a Proxy without authorization from New Eridu's Public Security is illegal, the siblings use Random Play as a legitimate cover while they carry out commissions in the various Hollows both within and outside of New Eridu, though their Proxy career is secondary to their investigation into "Hollow Zero", the oldest and largest Hollow which is located on the site of the old Eridu city which was destroyed in a massive Hollow disaster approximately 15 years before the events of the game.
All playable characters are associated with a faction. Agents wield one of five attributes: Electric, Ether, Fire, Ice, or Physical. Additionally, each Agent adopts one of five combat styles: Anomaly, Attack, Defense, Support, or Stun.

The development team cited Persona 5, Digimon World, and Street Fighter as influences for Zenless Zone Zero, influences from Street Fighter can be seen within the animation of characters during combat while the influences of Digimon World can be seen in the implementation of the in-game clock system. The development team stressed that Zenless Zone Zero has a unique style.
Characters in Zenless Zone Zero have different designs based on their faction; For instance, the design for Victoria Housekeeping characters is based on Victorian-era butlers and maids with tropes from horror movies. There is an emphasis on quality over quantity regarding the development of characters.
Unlike the character designs in MiHoYo's previous games such as Genshin Impact and Honkai: Star Rail, Zenless Zone Zero took a different direction with its variety of playable characters; There are non-human playable characters such as Ben Bigger, a grizzly bear, Soukaku, a blue-colored oni, and Billy Kid, a cyborg gunslinger. During the planning stages, these non-human characters were not intended to be present in the game but the team did find them fun and later incorporated them into the game.
According to the producer Li Zhenyu main protagonists Wise and Belle have independent roles from each other.
MiHoYo revealed the game in May 2022 and began holding closed beta tests, known as "Tuning Tests", for PC and iOS in August of the same year. A second closed beta test, called an "Equalizing Test", was also held for PC and iOS in November 2023. A third beta test, called an "Amplifying Test", was held for Android, PC, and iOS, in April 2024. During PlayStation's State of Play presentation in January 2024, a PlayStation 5 port of the game was announced as a timed console exclusive. A technical test was held for the PS5 in April 2024. The release date was announced in late May of that same year.
The game was released on July 4. To promote the game, HoYoverse collaborated with several graffiti artists to create Zenless Zone Zero-themed graffiti in 19 cities in Indonesia. An advertisement campaign on the Manila Light Rail Transit in the Philippines was held. A series of launch events titled "New Eridu City Tour" is being held in 19 locations worldwide. Another series of events titled "Zenless Dazzle Expo" is held within six comic conventions.
In July 2024, HoYoverse, through a collaboration between them and Lofi Girl, released a Zenless Zone Zero-themed Lofi Girl video featuring the character Belle though its HoYoFair YouTube channel, which features lo-fi remixes of select Zenless Zone Zero soundtracks.
Prior to the game's release, the Chinese video game news website 17173 noted that HoYoverse had significant experience with action games, considering Zenless Zone Zero as both a return to the genre and a potential breakthrough for the company. They believed that HoYoverse had yet to encounter significant rivals in the action game category and that Zenless Zone Zero could "stabilize and expand the user market." 17173 also emphasized the game's strong stylized design and trendy visual elements, noting that it inherited HoYoverse's expertise in the action category while presenting a distinct and unique work.
Eurogamer called the combat and day-to-day exploration exciting, and the world setting unique and immersive. Kotaku said its combat system is similar to miHoYo's previous game, Honkai Impact 3rd.
Paste, in its more critical review, praised the character design and variety, while calling the starter playable characters' usage repetitive and the TV mode dull and uninspiring. PC Gamer criticized the combat system by called it "mindless mouse clicking".
