Honkai: Star Rail developer and publisher HoYoverse has announced that the game’s Version 4.3 update will launch on June 1, 2026.
The new update will see the continuation of the Planacardia story as well as introduce the new playable 5-star character Mortenax Blade, updates to in-game events, and more.
Here’s a summary of what players can expect in the new story chapter of Version 4.3:
The secret sealed deep within Planarcadia will reach its official revelation in this version. At the end of the picturesque realm lies the divine husk of the Aeon, the Voracity. This ancient entity, presiding over desire and devouring, is the very crux of Blade’s wager on this journey. Bearing the flesh of Shuhu from within two hundred thousand Joy Ascendants, Blade has chosen to step onto the board himself. He seeks to borrow the power of the Voracity to melt away the Shuhu within his own body, bringing a final end to this long-enduring curse. However, whether this action ultimately leads to death or rebirth remains a blank in Elio’s script, and the answer will be witnessed firsthand by the Trailblazer.
Meanwhile, the Trailblazer will also depart for Inkford Hermitage, the boundary between this life and the World in Canvas, to transmit a warning regarding the threat of Asat Pramad to Graphia, who is stationed there. This ancestor of the Murata family, known as the “Mother of Imagenesis,” has lived in this world for a full millennium. As early as Amber Era 2148, she used a single brush to encanvas the entirety of Ahatopia, fending off the invasion of the Demons From Beyond, but at the cost of burdening every subsequent generation of the Murata family with the “Weathering Curse.” With the official debut of this millennial figure who has witnessed many major events in the cosmos, she may offer new answers regarding the Graphia family, Phantasmoon Games, and even the numerous mysteries surrounding Himeko.
As previously mentioned, Mortenax Blade is the new 5-star character that will be added in the new update. He is a Fire-Type Path of Nihility character. Here’s a description of his abilities:
In combat, Mortenax Blade can use his Ultimate, “Fornax Ex Corpore” to deploy a special Bounded Field and enter an enhanced state. While the Bounded Field is active, all enemies receive increased DMG. Upon entering this enhanced state, Mortenax Blade unlocks his Skill, utilizing a Sword Formation to deal even more DMG to enemies while gaining a brand-new, more powerful Ultimate. Furthermore, every time an ally attacks an enemy, they inflict a debuff on the target and accumulate a special Charge for Mortenax Blade. Once this Charge is full, he automatically uses his Skill once and regenerates extra Energy.
If a player obtains Mortenax Blade from his Warp banner, they can also claim a brand-new Trailblaze Outfit piece called the “Karmic Fire of the Distant Shore” for free as part of the “Gift of Tempered Blade” event.
Apart from Mortenax Blade, Yao Guang’s rerun banner will be available during the first half of the update, while Cyrene and Phainon’s limited rerun banner will be available during the second half.
Version 4.3 will also introduce new content for events, including the “Wispae Amusement Park” within the World in Canvas.
A new “Starward Mode” will also be added to three challenge gameplay modes: Memory of Chaos, Pure Fiction, and Apocalyptic Shadow. The new mode will task players with setting up three teams to take on three different stages.
HoYoverse has also announced its latest collaboration with UGreen, which will include new merchandise as well as online and offline events across multiple countries and regions.
Honkai: Star Rail Version 4.3 is scheduled to launch on June 1, 2026. The game is currently available on PC, PS5, iOS, Android.
