Kafka and Robin, two characters from Honkai: Star Rail, will appear in New Eridu as collaboration characters. The same broadcast confirmed that Zenless Zone Zero Ver.3.3, titled Take Flight Once More, launches on October 21 and introduces S-Rank Agents Fione and Severian. Fione is a Fire and Anomaly unit who applies Fire Erosion and revives with full HP after a fatal blow. Severian is a Wind and Attack unit who evades and counterattacks, building energy for consecutive slashes. Ver.3.3 also adds mech combat with switchable melee and ranged modes, a new Labyrinth Mysteries season called Strange Trials, a test run of the Fairy team composition feature, and a Steam version. The crossover runs the other direction as well: Honkai: Star Rail Ver.4.8 will bring Zenless Zone Zero characters Ellen Joe and Astra Yao to the Astral Express.","whyItMatters":"HoYoverse is running the crossover in both directions at once, so the same announcement commits each game to hosting the other's cast in adjacent versions.","webCardHtml":"\u003cp\u003eRobin and Kafka arrive in New Eridu as the Ver.3.4 collaboration characters, which HoYoverse confirmed in a post from the Zenless Zone Zero official X account: \u0026#34;Kafka and Robin descend upon New Eridu, inviting all Proxies on a special, heart-pounding journey.
