You can change worlds by opening the world menu and selecting a different server from your list

Once Human lets you play on multiple worlds (servers) with the same account. To move between them, open your main menu, find the world or server selection screen, and pick a different world from the list. Your character and progress stay tied to that specific world — switching worlds does not move your buildings, inventory, or progress forward. Each world is separate.

The exact menu path depends on whether you are in the main lobby or already in a world. From the lobby, you will see world options directly. If you are already playing in one world and want to switch, you need to return to the main menu first, then select a different world. You cannot fast-travel between worlds while playing.

Key Takeaways

  • Switching worlds requires returning to the main menu — you cannot change worlds from inside active gameplay.
  • Each world keeps your character, buildings, and inventory separate, so progress on World A does not carry to World B.
  • You can create multiple characters across different worlds or use the same character name on different servers if the name is available.
  • Some servers may have queue times during peak hours, so switching to a less populated world can reduce wait times.

What happens to your progress when you switch worlds

Your buildings, stored items, and character level remain on the world where you built them. If you have a base on World 1 with 50 storage boxes and level 15 progress, switching to World 2 starts you fresh — no buildings, no stored items, and your character begins at level 1 again on that new world.

This separation is permanent for that world. You do not lose your World 1 progress by playing World 2, but you also cannot move items or buildings between worlds. If you want to return to World 1 later, your base and inventory will still be there, though they may have been affected by decay or other world mechanics depending on how long you were away.

When to switch worlds and why players do it

Players switch worlds for several reasons. A world might be full or have long queue times during peak hours, so moving to a newer or less populated server gets you in faster. Some players want to try different playstyles — building a cooperative base on one world and playing solo on another. Others switch because their original world is ending or merging with another server.

If you are part of a clan or group playing together, you will need to coordinate which world everyone is on, since you cannot interact with players on different worlds. Switching to join friends or a community is a common reason to move servers.

How to manage multiple characters across worlds

You can create separate characters on different worlds using the same account. Each character has its own name, level, and progress. If you want the same character name on multiple worlds, you can use it as long as that name is not already taken on the new world.

Managing multiple characters means keeping track of which world each one is on and what progress you have made. Some players use notes or a spreadsheet to track their bases, resources, and goals across worlds. There is no in-game tracker that shows all your characters at once, so organization is up to you.

What to do if a world is full or has a queue

If your preferred world is full, you will see a queue time when you try to enter. You can either wait in the queue or switch to a different world immediately. Newer worlds or less populated servers usually have no queue and let you in right away.

Queue times vary depending on the time of day and how many players are online. Peak hours (evenings and weekends) tend to have longer queues. If you are in a hurry to play, switching to an alternate world is faster than waiting. You can always return to your main world later when the queue is shorter.

Server merges and world closures

Once Human may close or merge worlds as the player base changes. If your world is scheduled to close, the game will notify you in advance. When a closure happens, your character and progress are usually transferred to a designated new world so you do not lose everything.

Check the in-game news or official announcements if you notice your world is less populated than usual. Developers typically give players time to prepare before a world closes, and they handle the transfer automatically. You do not need to manually move your character — it happens on the backend.

Frequently Asked Questions

Can I transfer my base or items to a different world?

No. Each world is completely separate. Your buildings, inventory, and progress stay on the world where you created them. You cannot move items or buildings between worlds, so you will need to rebuild on a new world if you switch.

Will my character name be available on a different world?

Usually yes, unless another player on that world already has the same name. Character names are unique per world, not account-wide. If your preferred name is taken, you can choose a different one or try a different world where it might be free.

Do I lose my progress if I switch worlds?

Your progress on the original world stays there. Switching worlds does not delete anything — it just means you start fresh on the new world. Your old world remains unchanged, and you can return to it anytime to find your base and inventory intact.

What happens to my base if I do not log in for a long time?

Bases may decay or be removed depending on the world's inactivity rules. Check the server settings or patch notes to see how long you can be away before decay begins. Some worlds have longer grace periods than others.

Can I play with friends on different worlds?

No. You can only interact with players on the same world. If you want to play together, you and your friends need to be on the same server. Coordinate which world you are joining before you start playing.
