You can add Friends using the Friends feature. It allows you to add players to your Friends List by using their IDs, through Facebook or simply clicking on their profiles. You can invite your friends to Group battles and Private matches. Let’s say, you meet a player, who's as cool as a point-blank shot with the Traitor, and want to play with them, but you are members of different Clans. No problem! Just click on their Profile and add them to your Friends List. Friends tab has 4 subtabs: All, Clan, Friends Ingame and Facebook. You can see lists of added players and check whether they are online.
