Call of Duty Black Ops III features nine new character classes called “Specialists” in its online multiplayer. A Specialist must be chosen alongside a custom loadout before jumping into a match.
Specialists are identified by a unique Callsign. Each has one special ability and one special weapon. You must choose one of these before entering a match, both cannot be used at the same time. These abilities and weapons become available after enough time has passed and/or score has been earned in a game. A circular gauge in the bottom right corner will display how long until the special ability or weapon is available for use. The time it takes for the gauge to fill depends entirely on the weapon or ability being used.
