If you are the one being invited, it’s important to know how to accept the invite so that you can start playing co-op with your friends. Alternatively, you can just approach to their character in-game and hold the “Invite to Team” button when prompted. To invite a player to your team, select their name in the Social tab once more and select Invite. Once you and your friend are on the same server together, the next step is to invite them to your team.
Select their name, then choose whether you want to Join or Invite them. To do this, simply navigate to the Social tab within the Menu screen, then select either the Recent, Team, or Friends categories to select a player from the list. To play co-op with a friend, you can either send them an invite to join your server, or you can accept an invite to join theirs. Assuming this is the case, the next step is to start up the game and join each other for a co-op play session on the same server. In order to team up and play co-op with a friend in Fallout 76, players must first ensure that they are playing the game on the same platform as one another.
