Taking the stage during Microsoft's (non-livestreamed) Gamescom showcase, Activision has announced that Call Of Duty: Ghosts will provide dedicated servers as standard on Xbox One, taking advantage of Microsoft's enormous server infrastructure and cloud hosting. Thus "ensuring the best multiplayer experience will be on Xbox One," according to Xbox Wire.
Infinity Ward also revealed a new multiplayer mode, Blitz, that sees teams attacking score zones on opposite sides of the map. When a player enters the score zone, they're teleported back to base for another run. We'll see more of it tomorrow.
