Honkai: Star Rail unlocks

Restored Sept 29 2026 under new ids — this is Version 4.4 content, still permanent. Wording is carried from the 4.4 list that was verified in-game; the retired ids hsr-u-001..016 stay retired.

• Trailblaze Mission — Planarcadia: "In Ravages Does the Whistle Sound"

  The Version 4.4 main story, permanently available. HoYoverse recommends it before "Astropolis — To Roll the Stars in Astropolis".
• Complete the Planarcadia story progression and exploration
• Trailblaze Continuance — the Fate collaboration continuation

  The Imagenae / Holy Grail War content tied to the second Fate collaboration phase. Permanently accessible once unlocked, though its limited event rewards have expired.

Restored Sept 29 2026 under new ids — this is Version 4.4 content, still permanent. Wording is carried from the 4.4 list that was verified in-game; the retired ids hsr-u-001..016 stay retired. For each area, completionists also want treasure chests, puzzles, elite encounters, readables, Data Bank entries, achievements, NPC interactions and area collectibles.

• Unlock and fully explore Desolate Maw’s Demonhold
• Unlock and fully explore Fallen Star’s Cradle

Restored Sept 29 2026 under new ids — this is Version 4.4 content, still permanent. Wording is carried from the 4.4 list that was verified in-game; the retired ids hsr-u-001..016 stay retired.

• Unlock Echo of War: The Comedy of Doom

  Joins the recurring three-per-week Echo of War reward pool once unlocked.
• Unlock Divergent Universe: Bugs Incoming

  Complete its first-time progression and reward objectives. The 4.5 Arcadian Chronicles expansion builds on this rather than replacing it.
• Unlock and farm the Version 4.4 Planar Ornament sets

  Fallen Star Anchorage and Cosmic Life Sciences Institute.
• Clear the Currency Wars content added in 4.4

  One-time stages and first-clear rewards. Once the permanent progression is done, only the shared weekly Points track remains.

Both need Trailblaze Level 21. Finality’s Vision is a version-limited early-access shortcut, not a standing way in — in 4.5 it reached this story, in 4.6 it reaches the next chapter below.

• Trailblaze Mission — "Astropolis: To Roll the Stars in Astropolis"

  Trailblaze Level 21 or higher. Recommended first: "Planarcadia — In Ravages Does the Whistle Sound". Progressing this is what opens the rest of Astropolis — the systems and the exploration content both hang off it.
• Trailblaze Continuance — "Astropolis: How to Lose Your Way to the Top: The Zero-Dollar Strategy"

  Trailblaze Level 21 or higher. Best after the mission above. Completes the permanent story progression added in 4.5.

Space Anchors first — they make the rest of each area cheap to finish. Completionists also want the puzzles, encounters, treasures, readables, Data Bank entries and achievements in each.

• Unlock and explore Astropolis Central District

  The main headquarters district of Interastral Peace Entertainment. Activate the Space Anchors, then clear the exploration objectives, puzzles, encounters and treasures.
• Unlock and explore Lodestar Tower

  The behind-the-scenes industrial area of Astropolis. Activate its Space Anchors and collect the one-time treasures and collectibles.
• Unlock Skycall Aery

  At the top of Lodestar Tower. Finish the associated story progression and exploration, and collect the treasures, achievements and readables there.
• Finish Astropolis exploration0 / 5

  The sweep after the story is done — check each part rather than trusting the map to look complete.

  • Basic Treasures and the other one-time exploration rewards across the new maps
  • The new puzzles and interactable objectives
  • New Data Bank entries
  • Newly added readables and Messages
  • The Astropolis achievements

A new Astropolis-focused progression system layered onto the existing Furbobocom. Parts of it need real story progression and CANNOT be reached through Finality’s Vision alone — so the early-access shortcut does not finish this group.

• Unlock the Furbobocom "Press Affairs" management system

  Progress far enough through the 4.5 Trailblaze Mission for the Press Affairs panel to appear. Then dispatch furbos onto reports, produce TV shows, develop the newsroom and work through the furbo staff in the new management area.
• Progress Furbobo Freebies and claim its one-time rewards

  Raise the Freebies level through the new Furbobocom content. Keep going until the new exploration gadget unlocks — that is the milestone worth reaching.
• Unlock the Energy Sensor treasure gadget

  Earned by raising Furbobo Freebies. Reveals the location of one Basic Treasure on Astropolis maps per use, which is what makes the exploration sweep above finishable.

An EXTENSION of existing 4.1–4.4 progression, not a reset — nothing already earned is rolled back. These are permanent objectives rather than weekly ones, which is why they sit here and not in the weekly bucket.

• Raise Synchronicity through the newly added levels

  Keep running Divergent Universe for Synchronicity Points, then claim each newly added milestone reward.
• Complete the new Stable Computing Array objectives

  Review the new challenges after entering Divergent Universe and clear each one for its reward.
• Unlock Threshold Protocol 9

  Gated behind the required Astronomical Division difficulty. Clear the associated high-difficulty content for its first-clear rewards.
• Unlock Astronomical Division X10 — "Monarch of Myriad Machines"

  4.5 raises the difficulty ceiling to X10. Work up through the preceding stages to reach it.
• Clear Astronomical Division X10

  Optional high-difficulty endgame — NOT required for the normal weekly Divergent Universe routine. Claim the first-clear and Stable Computing Array progression rewards.
• Advance Moonlit Tales to the new maximum star ratings

  4.5 raises the star ceiling on items. Run Divergent Universe for the progression needed, then upgrade the newly expandable items and claim the associated bonuses and Secrets.
• Fill the new Divergent Universe collection entries0 / 5

  Completionist rather than mandatory. Revisit your collection records after the update — newly added entries do not announce themselves.

  • New Supplicant’s Masks
  • New Equations
  • New Curios
  • New Weighted Curios
  • New Occurrences
• Defeat "Paramount Bliss Inverted: Illwish Archlotus (Complete)"

  Added to the Third Plane boss pool in 4.5. Borisin Warhead: Hoolay (Complete) was REMOVED from that pool in the same update, so the rotation you remember has changed.

Confirmed in-game, Sept 29 2026.

• Trailblaze Mission — "Astropolis — Dance With the Beast Before Moonrise"

  Permanent, in 5 parts. Trailblaze Level 21 or higher; recommended after "Astropolis — To Roll the Stars in Astropolis" above. During Version 4.6 it can also be played early through Finality’s Vision.

  Reward Across all 5 parts: Stellar Jade ×461, Credits ×560,000, Arcadian Token ×2,380, Traveler’s Guide ×32, Lost Crystal ×13, Refined Aether ×4, and four Light Cones — The Flip Side of Day, Brain in a Vat, Binge and Flex Over the Asylum
• Unlock and explore the Life Sciences Institute

  New 4.6 area — the private research centre of Yabuli, who leads the Technology Department.

Confirmed in-game, Sept 29 2026. The system is permanent; the "Astral Trendible" draws and the Park Souvenir vouchers are 4.6-only and live on the events page.

• Set up the Pet House and an Astral Imagea squad

  The Pet House is in the Party Car; up to 3 Astral Imageas can be summoned as a squad. HoYoverse recommends finishing "Astropolis — Knowledge, Silence, Passing By" and unlocking the Life Sciences Institute first, since the Astral Imagea Park sits there.

Confirmed in-game, Sept 29 2026.

• Unlock Cavern of Corrosion: Path of the Secret Actor

  A new Cavern of Corrosion stage. Farm it only if you want its sets.

  Reward Cavern Relics "Dreamlit Actor" and "The Edacious Heretic"

Most of this unlocks on its own through the story and exploration. It is listed because the gaps are only visible if you go looking once each story arc is finished.

• Claim the Version 4.4 achievements

  Added alongside Planarcadia, its two areas and the Fate collaboration continuance. Check the Achievement menu once that arc is done.
• Claim the newly added Version 4.5 achievements

  Added alongside the Astropolis story, the exploration and Furbobocom. Check the Achievement menu once the main story and exploration are done.
• Claim the 28 new Version 4.6 achievements

  Added alongside "Dance With the Beast Before Moonrise", the Life Sciences Institute and Astral Imageas. Check the Achievement menu once that chapter is done.
• Collect the new Data Bank and collectible entries0 / 5

  Check each after finishing Astropolis rather than assuming story progress caught them all.

  • Data Bank entries
  • Readable items
  • Messages
  • Discs
  • Loading-screen lore entries
