The Honkai: Star Rail × Fate[UBW] collaboration was first announced with Saber and Archer. A later official HoYoLAB announcement added Gilgamesh and described a limited five-star Gilgamesh Warp, plus a time-limited choice between Gilgamesh and Archer. Those announcements do not prove that the characters, Warp, or free selection remain available now, so treat the dates below as historical announcement details rather than a current event schedule.
Which Fate characters were revealed for Honkai: Star Rail?
Three characters were named in the official announcements: Saber, Archer, and Gilgamesh. Saber and Archer appeared in HoYoverse’s original collaboration PV, while Gilgamesh was introduced in a later HoYoLAB character announcement. The posts establish the names and event details below, but they do not provide a complete gameplay roster, release calendar, or current availability status.
| Character | Announcement context | Details stated by HoYoverse |
|---|---|---|
| Saber | Original collaboration PV, July 10, 2025 | Named in the Japanese voice-over information; Japanese voice actor listed as Ayako Kawasumi. |
| Archer | Original collaboration PV, July 10, 2025 | Named in the Japanese voice-over information; Japanese voice actor listed as Junichi Suwabe. |
| Gilgamesh | Later “Extraterrestrial Satellite Communication” announcement | Described as a collaboration character with a limited five-star Gilgamesh Warp. |
That distinction matters. The first reveal is often summarized as a Saber-and-Archer collaboration, but the later Gilgamesh post means those two are not the only characters officially announced for the project.
What did the original Saber and Archer announcement reveal?
The collaboration’s official name
HoYoverse’s July 10, 2025 HoYoLAB post used the title “Honkai: Star Rail × Fate[UBW] Collab PV — ‘A Long ‘Fated’ Meeting.’” The bracketed UBW label identifies the Fate/stay night: Unlimited Blade Works connection used in the announcement. This is the formal tie-in name supplied by the publisher, rather than a fan-created description of a crossover.
The Japanese voice cast information
The PV post’s Japanese voice-over information lists Ayako Kawasumi for Saber and Junichi Suwabe for Archer. These are voice-cast credits attached to the collaboration presentation; the post does not by itself establish every language option, a complete dialogue list, or the characters’ combat roles.
A preview of Japanese original audio settings
The same July post previewed a Version 3.5 option for collaboration-character interaction, idle, and battle voice lines. The stated route was Character Details → Profile → Voice, where players could switch those lines to Japanese original audio. Because the wording was a preview, it should not be treated as proof that the setting still exists under the same label or in the same location in the current game client.
How did the later Gilgamesh announcement change the lineup?
Gilgamesh was a separate, later reveal
HoYoLAB later published “Extraterrestrial Satellite Communication: Gilgamesh.” The available result for that post shows the date as May 22 without a year, so no year can be assigned confidently. It should therefore be read as a later announcement than the July 10, 2025 PV, not folded into the wording of the original reveal.
The announcement described a limited five-star Warp
The post described a limited five-star Gilgamesh Warp. That wording establishes the announced banner type and rarity, but it does not establish the banner’s current status, rerun plans, drop rates, pity rules, combat kit, or performance compared with other characters.
The free choice was Gilgamesh or Archer
HoYoverse’s announcement said players could choose either Gilgamesh or Archer for free from July 24 at 12:00 server time through the end of Version 4.6. The year is not included in the available result, and the post describes a version-based closing point rather than a permanent unlock. “Either” indicates a choice between the two named characters; it should not be read as an announcement that every account receives both.
Are Saber, Archer, and Gilgamesh available right now?
Current availability is not established by the announcements. A finite offer tied to Version 4.6 can expire when that version ends, and an old PV cannot confirm that a banner or selection screen remains live in a later client.
To check your own account without relying on reposted schedules:
- Read the game’s current in-game notices for the Fate collaboration and compare the stated dates with your server’s clock.
- Inspect the active Warp listings for a Gilgamesh banner rather than assuming that the announced limited Warp is still running.
- Check the character-selection or event interface for the Gilgamesh-or-Archer choice, if the notices say the offer is active.
- Confirm your game version and server region. “12:00 server time” is tied to the server, not necessarily to your local time zone.
- Use a current official notice as the deciding evidence if it conflicts with a screenshot, video, or older social post.
This process separates what HoYoverse announced from what the live service currently offers. Neither the July 2025 PV nor the later Gilgamesh post supplies a present-day expiration confirmation.
What exactly was promised about the voice-over switch?
The July 2025 post previewed a setting for the collaboration characters’ interaction, idle, and battle voice lines. It pointed to Character Details → Profile → Voice and specifically discussed switching to Japanese original audio. The statement is narrower than a promise that every menu line, cinematic, or character in the game can be changed independently.
What the preview does establish
- The option was associated with Version 3.5 in the preview.
- The affected material included interaction, idle, and battle voice lines for collaboration characters.
- The listed navigation path was Character Details → Profile → Voice.
What still needs a current check
- Whether the feature shipped exactly as previewed.
- Whether the labels or menu path changed in later versions.
- Whether the setting applies to all collaboration characters or only specific lines.
If you are documenting the feature for a guide, use present-tense wording only after checking the current client or a current official version notice.
What is confirmed, and what has not been announced?
Confirmed by the official posts
- The crossover was branded Honkai: Star Rail × Fate[UBW].
- Saber and Archer were named in the original PV.
- Ayako Kawasumi and Junichi Suwabe were listed for Saber and Archer’s Japanese voice information.
- Gilgamesh was later announced as a collaboration character.
- A limited five-star Gilgamesh Warp was described.
- A free choice between Gilgamesh and Archer was stated for July 24 at 12:00 server time through the end of Version 4.6.
Not established by those announcements
- Current banner or event availability.
- A full list of collaboration characters beyond the three names above.
- Combat paths, elements, skills, eidolons, or tier-list standing.
- Drop rates, pity details, rerun dates, or permanent acquisition methods.
- Merchandise, a special game edition, or a physical bundle.
Keeping these categories separate prevents a promotional reveal from being mistaken for a complete gameplay database.
What is the collaboration timeline?
| Date or window | Announcement | How to interpret it |
|---|---|---|
| July 10, 2025 | “A Long ‘Fated’ Meeting” collaboration PV | Original reveal naming Saber and Archer and previewing the Japanese voice-line setting. |
| May 22, year not shown in the available result | “Extraterrestrial Satellite Communication: Gilgamesh” | Later official character announcement adding Gilgamesh and describing his limited five-star Warp. |
| July 24 at 12:00 server time through the end of Version 4.6 | Gilgamesh-or-Archer free choice | Finite, version-linked offer; the year and present availability are not established. |
The chronology explains why different articles give different answers. A page written from the first PV may mention only Saber and Archer, while a later page can correctly add Gilgamesh. Neither version should imply that the announced offer is still active without a current notice.
Is the Unlimited Blade Works Blu-ray official collaboration merchandise?
No. A Fate/stay night Unlimited Blade Works Blu-ray is relevant companion media for readers who want the source anime, but the available announcement material does not identify a Blu-ray as official Honkai: Star Rail collaboration merchandise. Edition, region, current listing, and eligibility for any retail program must be checked separately.
That distinction is useful when looking for related products: the crossover announcement concerns in-game content, while a home-media release belongs to the broader Fate/stay night franchise and should not be presented as a game bundle.
What should players take from the character reveal?
The accurate short answer is: Saber and Archer were the original announced characters, and Gilgamesh was added in a later official announcement. The later post also described a limited five-star Gilgamesh Warp and a temporary free choice between Gilgamesh and Archer. Because those details are tied to dated announcements and Version 4.6, current players should verify the live notices and account interfaces before assuming any character or reward can still be claimed.
Frequently Asked Questions
Was Gilgamesh part of the first Fate collaboration PV?
No. The first PV identified in the official material names Saber and Archer. Gilgamesh appears in a separate later HoYoLAB announcement, so articles based only on the PV will not include him.
Did the announcement give every player both Gilgamesh and Archer?
The stated offer was a choice of either Gilgamesh or Archer for free. That wording describes one selection, not an automatic grant of both characters; the live event interface would determine how the choice was implemented.
Why does the Gilgamesh announcement not have a year here?
The available official-post result displays the date as May 22 without a year. Assigning a year would go beyond the dated information supplied, so the announcement should be cited with that limitation.
Can I still switch the collaboration characters to Japanese voices?
The July 2025 PV previewed a Japanese-original-audio option under Character Details → Profile → Voice for interaction, idle, and battle lines. Since it was presented as a Version 3.5 preview, check the current client or an up-to-date official notice before assuming the option and menu path are unchanged.
