The Friends system is a new feature coming to Asphalt Legends UNITE that gives players the ability to add and manage their own Friends List. Players that are friends can chat, check their online status and join in races together.
To add a player as a friend, ask your friend for their Player ID (the code that can be found on your friend's profile). When you have your friend's ID, enter the new Friends section (accessible through a shortcut on the game's top bar) and enter the "Add Friends" subsection. Once there, search for your friend's ID and send them a friend request. If the other player accepts it, they will appear in your Friends List.
