The upcoming Call of Duty: Ghosts executive producer Mark Rubin took to twitter to "test" his new phone's video with a teaser for the new game.

An in-game menu for “squad” gameplay is shown. The clip also shows “Online Play” and “Option” menus. Just as the clip fades, the title “Squads” comes into view. Rubin has not stated specifically which game the clip is from but with the Ghosts’ multiplayer unveiling on 14 August, people can put two and two together.

The Call of Duty: Ghosts multiplayer unveiling will be held in Los Angeles and will be live streamed on Xbox Live and on the game’s website at 10.30am PT/1.30pm ET.
