Blue Protocol or Star Resonance? A Guide to Choosing the Correct Game
Understand the original Blue Protocol closure and distinguish Blue Protocol: Star Resonance before following a build, installing a client or buying services.

In this guide 4 sections
Searching for a Blue Protocol guide can lead to information about two different products. Before choosing a class build or planning progression, identify whether the page concerns the original Blue Protocol or Blue Protocol: Star Resonance. Their shared name does not make instructions interchangeable.
What happened to the original Blue Protocol?
The original game's official Steam news feed announced that Japanese service would close in January 2025 and that the planned Western release with Amazon Games would not proceed. Older technical-test and launch-preparation articles therefore describe a project whose release plans changed. Official Blue Protocol service announcement.
Do not use an old invitation, roadmap or gameplay clip as proof that the original official service is currently available. A third-party page offering access needs more than familiar artwork to establish what it actually provides.
What is Blue Protocol: Star Resonance?
Star Resonance has its own official store listing, developer and publisher information. That listing describes an MMORPG expanding the Blue Protocol universe, with activities including raids, exploration, fishing and crafting. Treat it as the specific product named on that page. Official Star Resonance listing.
Before installing, compare the complete title, supported platform and regional availability. If friends intend to play together, confirm that everyone is looking at the same service rather than assuming the words Blue Protocol are sufficient.
Choose guides that identify their version
A useful build guide should name the game, current patch or season and the activity it addresses. Check that its class names, menus and equipment exist in your client. If the screenshots and your interface disagree, pause before spending materials to reproduce the build.
Do not assume characters, purchases or progression from the original game transfer to Star Resonance. Such a transfer would require a specific official statement; visual similarity is not evidence.
Prepare a first session around the actual client
Follow its tutorial, select one role you want to learn and choose a small story or exploration objective. Read ability and item descriptions before investing broadly. If you encounter a guide for the other product, keep it as historical context rather than a current instruction sheet.
The most useful first step is therefore product identification. It prevents an outdated article from becoming an expensive or frustrating progression plan.
