Are you on PS 4?. My settings on the PS 4 are in my mother tongue, therefore, I am not sure if the categories have exactly that name, but I am confident that you will know what I mean. Normally, you can enter the Message section and there, you can find the section Recent Encounters. You have to open the agent's profile and send an invite.
To Add/Invite A Friend To Your Game:
- Create a UPlay Account
- Make sure to exchange UPlay accounts with any friend you want to Add/Send an Invite
For PS4 and PC:
- Open Menu
- Click "Group Management"
Here is where you can Join/Create groups w/ your friends and/or other players.
Simply click on your friend's name and select ‘Invite to Group’.
Your friend should now accept the invite and they’ll be brought into your game.
Alternatively, if your friends haven’t change their privacy settings to private, you can join their group by going down to their name and selecting the ‘Join Group’ option. Once you’ve done this simply meet up in the huge world of Manhattan and you’ll be free to take on the virus outbreak together.
NOTE: Friends that are still in the "Brooklyn" part of the game will not be able to join you in Manhattan until they have completed the first part of the game. When you scan your map, your friends will appear in ORANGE CIRCLES, you can then clock on them and join them OR fast travel to them.
For PC:
- Use the shortcut, Shift + F2 to invite friends. Once completed, your friend should show up in the group management in the game menu.
Hope this helps,if you are still experiencing issues after trying this method, contact Support.
