Multiplayer

Satisfactory can be played in Single Player without servers, or in server based Multiplayer, with up to 4 players officially supported, but with no hard player-limit. There are not currently dedicated servers, meaning that servers are hosted on the machine of one of the players, while they are playing. But there are plans to add them, most likely post-alpha.

Server Options
When hosting a multiplayer server you can choose the following settings:

Privacy
There are no plans for a "Public" option, due to griefing concerns.
 * Friends - Anyone on your friends list can join your game without invitation
 * Private - Players can only join your server if sent an invite.
