Welcome to the Robocraft JP Homepage!
日本語 / English
This is the homepage of Robocraft JP, an unofficial Robocraft server operated in Japan.
The supported Robocraft version is the final Steam release (2021 version).
The server is operated using the server software developed in NGnius’s OpenJam project.
We usually discuss this server in the Discord community called RC15JP. You can find the invitation link under “Community” in the upper-right corner.
There is also a Robocraft US instance hosted in the United States. Since the join steps are different, please check the Robocraft US Discord via “Community” in the upper-right corner.
How to Join the Server
1. Please register an account using the “Register” link in the upper-right corner.
2. Obtain the game from Steam, or download the game archives for your OS from the “Download” link in the upper-right corner.
3. From the “OpenJam” link in the upper-right corner, access the Server List. Click “Connect” on the Robocraft JP entry to download the configuration file.
4. If you are using the Steam version, open your Steam Library → Robocraft → Properties → Installed Files → Browse (the display may vary depending on your OS).
When the file explorer opens, place the downloaded configuration file inside that folder.
If you downloaded the archive version, extract it and locate the folder containing executables such as Robocraft.exe. Place the configuration file in that folder.
5. For the Steam version, simply press the Play button. For the archive version, run Robocraft.exe (or the appropriate executable) to start the game.
