We don't know much about the multiplayer component for Call of Duty: Ghosts, but Infinity Ward may have just given us a hint about what to expect this fall.

Executive producer Mark Rubin took to Twitter to "test" his new phone, and submitted a brief video teasing Call of Duty: Ghosts.

As you can see in the menu, there will be a mode called Squads in Ghosts. There are three menu choices you can see, with Online and Options visible, but a third option blurred out. Activision typically keeps Call of Duty multiplayer details as the last bit of info shared with the world, but we do know there will be a co-operative component included in this entry already.

Whether or not that coop mode ends up being Squads remains to be seen, but the hint at least gives us some indication Infinity Ward is almost ready to talk multiplayer for one of 2013's most anticipated games.
