Your players join your Icarus server with its Server Address, shown on the server's Overview page in the panel. Icarus is a co-op survival game from RocketWerz where small groups drop from orbit onto a hostile planet to complete timed missions called prospects (or to build up in the Open World); a hosted dedicated server keeps your prospects available around the clock without anyone's PC acting as the host.
Join in a few steps
- Open your server in the panel. If the status badge says Offline, click Start and wait until it says Online. See How to start, stop, restart and force-stop your server.
- On the Overview page, click the copy icon next to Server Address. It looks like
address:port.

- Launch Icarus from Steam and select your character.
- From the HAB menu, select the Join Session button.
- Use the toggle in the top right corner of the screen to switch the browser to dedicated servers.
- Find your server by the name you set in the panel (Server Name), select it and join. If you set a Join Password, enter it when asked.
- If the server is not running a prospect yet, you land in the Server Lobby instead. From there you can start a new prospect or load an existing one.
Ports
Players connect through the server browser or with the port shown in the Server Address on the Overview page. The server also uses a separate Steam query port that is set up for you automatically, so there is nothing to change.
Game version
On our server the game files are checked against Steam every time the server starts while Auto Update is switched on, which is the default, so restart the server after an Icarus patch to pick it up. Turn Auto Update off only if you need to stay on a specific build.
If you cannot join
- The server must be Online. Check the badge at the top of the page.
- Copy the address again from the panel. A missing or mistyped port is the most common cause.
- Make sure every player runs a compatible game version.
- Check the password, if you set one. See How to set up your Icarus server.
