Activision released a trailer for Call of Duty: Ghosts. The latest video details the game’s Clans, a major part of Ghosts‘ multiplayer experience. Joining Clans — besides playing death matches with your friends — grants additional experience points and rewards. Also, another tidbit: Clans will not be cross-platform on Wii U. You cannot join a clan with friends who have Ghosts on other platforms. View the trailer above to learn more about how Clans change COD’s kill fest.
