If you just hopped on the Astral Express for the first time, one of the first questions you’ll probably ask as you scroll through the navigation screen is how many worlds does honkai star rail have to explore. I remember being shocked when I finished the first arc and realized there was far more content waiting beyond the starting space station, even after I’d already put 12 hours into the game. Each world has its own distinct tone, enemy types, story beats, and hidden loot, so you’ll never get bored bouncing between them as you progress through the Trailblaze quests. Even veteran players revisit old worlds regularly to farm materials, complete missed side quests, or hunt for hidden achievements they skipped on their first playthrough.
How Many Worlds Does Honkai Star Rail Have As Of The Latest Update?
Right now, there are 4 fully released, playable worlds available for all players to access, with no paywalls locking any core story or exploration content. HoYoverse adds new major worlds every 3 to 4 major version updates, so the list will keep growing as the game’s overarching story unfolds. Each world unlocks sequentially as you complete the main Trailblaze Quest line for the previous area, so you won’t accidentally stumble into a high-level world you’re not prepared for. All released Honkai Star Rail worlds are 100% accessible for free, no premium purchase required to unlock story content.
Some players debate whether the Herta Space Station counts as a full world, but it’s officially categorized as one by the game’s devs, and it has the same amount of exploration content, side quests, and hidden chests as the other planets. You’ll spend your first 5 to 8 hours here learning the game’s core mechanics, so it’s just as fleshed out as the larger planets you’ll unlock later.
Breakdown of Each Honkai Star Rail World’s Unique Content
Every world in HSR has a distinct aesthetic, lore, and gameplay quirks that set it apart from the rest. Knowing what to expect from each one can help you plan your character builds and resource farming runs ahead of time.
The Herta Space Station is your starting point, a high-tech research facility run by the eccentric Herta, one of the members of the Genius Society. It’s home to the Simulated Universe, one of the game’s core endgame modes, and it has a lot of hidden lore snippets about the Aeons and the history of the Astral Express. The enemies here are mostly automated security robots and stray interstellar beasts, so they’re easy for new players to take down.
Jarilo-VI is the first full planet you’ll unlock, a frozen world recovering from a centuries-long ice age called the Eternal Freeze. It’s split between the opulent upper city of Belobog and the gritty, frost-bitten undercity, with plenty of open snow plains and abandoned mining facilities to explore between main story quests. Each world has its own unique set of materials you need to ascend characters and light cones, so you’ll be coming back to Jarilo-VI regularly if you main ice or physical characters like Seele or Clara.
The Xianzhou Luofu is a massive, Chinese-inspired space fleet run by the Xianzhou Alliance, a faction dedicated to hunting down the curse of immortality called Mara. This world has far more vertical exploration than the first two, with floating pavilions, hidden alleyways, and sprawling market districts to get lost in. It’s also where you’ll unlock some of the game’s most challenging weekly boss fights, so you’ll spend a lot of time here once you hit endgame.
Penacony is the latest released world, a vibrant, festival-themed planet that exists half in the waking world and half in a shared dream realm. Penacony is the first world to feature shifting map layers that change based on whether you're in the waking or dream state, so you’ll have to solve puzzles to switch between layers to find hidden chests and complete side quests. The story here is far more surreal than previous arcs, with lots of twists and unexpected character reveals that tie into the game’s overarching plot.
What Unlocks As You Progress Through Each Honkai Star Rail World
Unlocking a new world doesn’t just give you more story content to play through. It also unlocks core game modes, farming spots, and event access that you’ll need for endgame progression. Here’s a quick breakdown of the key unlocks tied to each world:
A lot of new players make the mistake of rushing through the main story as fast as possible to unlock new worlds, but that can backfire fast. Enemies in later worlds are significantly stronger than the ones you’ll face in the Herta Space Station and early Jarilo-VI areas, so you’ll hit a wall very quickly if you don’t take time to level and build your team. You should aim to have at least 2 fully built level 50 characters before you start the Xianzhou Luofu main quest to avoid getting stuck in boss fights that require specific team compositions to beat.
It’s also worth taking time to explore every corner of each world before you move on to the next one. Every world has dozens of hidden chests, secret side quests, and hidden achievements that give you free Stellar Jade, which you can use to pull for limited 5-star characters. I skipped most of the exploration on my first playthrough of Jarilo-VI, and I ended up going back a month later to collect all the Stellar Jade I missed when I wanted to pull for Jingliu. I found over 300 Stellar Jade I’d left on the table, which was almost enough for one full pull on the limited banner.
Upcoming Honkai Star Rail Worlds We Know About So Far
HoYoverse has already teased several new worlds that will be added to the game in future updates, as part of the Astral Express’s ongoing journey across the galaxy. Most of these are still in early development, but we have a few confirmed details from official story teasers and dev livestreams.
The next confirmed world after Penacony is the Planet of War, the home world of the character Acheron, which is ruled by the Aeon of Destruction. Teaser footage shows a war-torn, desert-like planet with constant ongoing battles between different factions, so it’s likely to have a darker, grittier tone than Penacony’s bright festival vibe. Leaked content suggests the next playable world will release sometime after Version 2.5, though no official release date has been confirmed yet.
We also know a world tied to the Aeon of Harmony is in development, as well as a planet that’s being consumed by the Swarm, a hostile interstellar force that’s been teased in side lore and Simulated Universe content. HoYoverse has not announced any plans to retire old worlds when new ones release, so you’ll still be able to go back and revisit all your favorite areas whenever you want.
One thing to note is that new worlds will always be balanced for the current average player level, so you won’t have to worry about new content being too hard to access if you’re a casual player who doesn’t grind endgame content every day. HoYoverse has a track record of making new story content accessible for players of all skill levels, so even if you only log in a few times a week, you’ll be able to play through new world arcs as they release.
So to wrap it all up, if you’ve been wondering how many worlds does honkai star rail have right now, the answer is 4 fully released, playable worlds, with more on the way in future updates. Each one has enough story, exploration, and side content to keep you busy for 20+ hours, even if you don’t count endgame farming and event content. Don’t rush through each world just to get to the next one—take time to explore, talk to NPCs, and hunt for hidden loot, because that’s where a lot of the game’s most fun and memorable moments are hiding. I still go back to Jarilo-VI every few weeks to walk around the snow plains and listen to the area’s soundtrack, even though I’ve already 100% completed all the content there.
