If you're interested in joining a clan or making sure yours is registered for Call of Duty: Ghosts, then you're going to want to jump into this post.

A trailer has been posted that gives us a brief overview of how clans will work in Call of Duty: Ghosts. You can either register your existing clan or join one in order to take advantage of many great benefits, such unlockable exclusive item, clan xp bonuses and the ability to participate in Clan vs. Clan battles.

New to Call of Duty: Ghosts is the cross-platform clan experience, which allows you to join a clan and contribute to the cause no matter what console version you're playing.

To help you manage all of this social awesomeness, the Call of Duty App is being introduced. You can use the Call of Duty App to manage your clan, check out stats, mess around with your clan emblem, chat with other clan members and send "rally up" messages that notify them that you're ready to put in some work.

You'll also be able to engage in Clan Wars, where you'll fight other clans in order to gain control of specific points on a map. Doing well in the Clan Wars means you'll unlock in-game xp bonuses and access to exclusive items. Sounds nifty, doesn't it?

Watch the trailer above and head to this site to check out the Clan Registration FAQ. Call of Duty: Ghosts will be released on Nov. 5 for PC, PlayStation 3, Wii U and Xbox 360. The next-gen versions will launch with their respective consoles.
