(Note: Online Party is available through Steam, available in the Nyakuza Metro + Online Party DLC)
To play Online Party, head to the Online Party terminal located in the main hub of Hat Kid’s Spaceship OR you can set your Online Party settings in the main menu. Be sure to check the box to enable Online Party, and enter the name of the lobby you’d like to join. If you leave the lobby name blank, you will only see occasional random guests, and they won’t be able to affect your game!
If you’re creating your own lobby, and the lobby name is already in use, you’ll join that game. If that happens, simply change your lobby name to claim your own! Your friends simply enter the lobby name from their terminals and they’ll join you!
