Whether you and another dweller were buddies long before the Vault door rolled open, or you just met while scouring the Wasteland for supplies, there’s nothing quite like the thrill of raiding a massive facility or hunting down a terrifying Scorchbeast alongside your closest pals.
If you’re playing on a console, your Friends List from that platform will automatically appear in the in-game Social Menu. If you’re on PC, you can send friend requests by opening the Social Menu and entering their Bethesda.net account names into the search bar. Alternatively, you can add players you meet in-game by selecting them directly on the Map and then choosing “Add Friend”.
Once your friends have received and accepted your request, you’ll be able see when they’re online, and can team up to join a world together. If you find yourself in trouble, any friends who are in your world can also become instant reinforcements by using the map to fast travel to your location.
