A trailer for the single-player campaign of Battlefield 4 tells the story of the USS Valkyrie, an aircraft carrier left blind in the Pacific with the destruction of the navy's Pacific command.

Beset by enemies, the men and women of the Valkyrie fight on land and sea to save their ship in a journey that ends up taking them to Shanghai, China. A new member of the player's squad, however, doesn't seem to be telling them everything about herself.

The trailer also features a soldier punching a dog, which can be easily interpreted as a shot across the bow of Battlefield's main rival Call of Duty: Ghosts.

Battlefield 4 hits current-gen systems on Oct. 29, and will be a launch title for PlayStation 4 and Xbox One.
