Explaining Honkai Star Rail Memory Bubbles
In the Herta Space Station, Memory Bubbles take the form of blue floating orbs. Although they can be found as soon as you complete The Voyage Continues Trailblaze Mission, which requires you to leave the station, they didn’t appear for me until I finished a few Adventure Missions (side quests).
I advise finishing the Simulated Universe: Second Closed Beta and then the several Road to Revival Adventure Missions if you’ve heard about these bubbles but can’t seem to discover them. After those have been taken care of, they should start to appear.
How to Utilize Memory Bubbles
When you first contact with a Memory Bubble, you’ll see a notification claiming that nothing has happened and that you should ask someone for information about them. That’s hardly much of a hint, but Herta is the only thing on the ship that seems to know more than everybody else.
After you interact with one of Herta’s puppets, at least a few of them will mention the Bubbles. In the Master Control Zone, to the left of the Central Passage Space Anchor, there is one puppet that is conveniently adjacent to a Memory Bubble.
The bubble may be spotted on the map in the image above, and the Herta puppet can be discovered at the top of the neighboring steps.
After this conversation, you can move about and engage with any Memory Bubbles you come across. Each presents a different memory with a blank screen and text dialogue. You’ll get 1000 credits if you make it all the way to the end.
