Questions about the game

Multiplayer, network and Internet

  • 1. How do I start a Stellar Overload multiplayer game session?

    To create a multiplayer game, in the main menu, click New Game and choose the game mode (Story or Creative). In the universe setup window set Multiplayer to YES.
    You can then choose the game’s visibility:

    • LOCAL: the game session will only be visible from computer on your local network in the LOCAL tab of the server list window
    • FRIENDS: the game session won’t be visible. To join you need to use Steam’s friend list, right click on the player hosting the game and choose “Join Game”
    • PUBLIC: the game session will be visible publicly by every Stellar Overload player in the PUBLIC tab of the server list window

    Another possibility is to start a dedicated server.

  • 2. How do I join a multiplayer game?
    To join a multiplayer game session, in the main menu, click Join. A window enabling you to choose the game server opens. This window is divided in two tabs to distinguish public servers (visible by everyone) from local servers (only visible on your LAN). To join one of these servers, you just need to select one of them, and then click Join (or double click on the server). If a password is required to join, a window will popup asking you to enter the password.
  • 3. Which ports are used to play in multiplayer?
    UDP ports 7777 and 27015 are used to play in multiplayer (LAN or Internet). In the case of a dedicated server, these ports are configurable in the script file used to start the server.
  • 4. How to setup my firewall in order to host a dedicated server over the Internet?
    You need to authorize the inbound traffic on UDP ports 7777 and 27015 (by default). You also need to forward these ports to the host computer in your Internet connection configuration.
  • 5. How many players can join a multiplayer game?
    A multiplayer game session created by the game is limited to 5 players. Using a dedicated server it is possible to extend this limit to a maximum of 32 players. However, for performance reasons we do not advise setting this limit to a number much higher than 5.
  • 6. Can I play over the Internet?
    Yes, you just need to create or join a “public” or “friends” multiplayer game session.
  • 7. What does the “Connection Timeout” error mean when I click the “Join” button?

    This message means that the time allocated to establish a connection with the server has expired.
    This error is displayed when the server cannot be reached (the server might be offline) or if there is a problem with your firewall / router configuration.

  • 8. Can I invite friends to play in my universe?
    Yes, you just need to create a “public” or “friends” multiplayer game session. Your friends will be able to see your server in the “Public” tab of the server list window (if you created a “public” game session) or to join your game by right clicking on your nickname in their Steam friend list and choosing “Join game”.
  • 9. Are there any official public servers?
    No. Currently, there is no official servers. Although, you can create your own server or join an existing server on Internet.
  • 10. How to install the dedicated server using Steam’s client?
    • Connect to Steam’s client using an account owning Stellar Overload
