Gi - Call of Duty: Ghosts multiplayer was revealed a few weeks ago at an event in Los Angeles. Multiplayer has always been a hallmark of the Call of Duty series. Call of Duty 4: Modern Warfare revolutionized the multiplayer field and set the bar for the way things were going to be done from there on. This November, Infinity Ward is going to be unleashing their latest installment in the series, Call of Duty: Ghosts. On August 14, Infinity Ward’s Mark Rubin presented the vision for Call of Duty: Ghosts multiplayer that is coming to the market. It is a safe bet to say that many fans are going to skip the campaign entirely and head straight to the arena with multiplayer.
