Clans in Call of Duty: Ghosts are no longer separated by platform, so your clan can span Xbox One, Xbox 360, PS4, PS3 and PC, Activision says. No matter which platform your friends are competing on – granted it's not Wii U – you can all enjoy the additional Clan XP that yields exclusive unlocks for the whole clan as you play together.

Early registration for clans is open right now. If you're in an existing clan in another Call of Duty game, your leader can now transfer over to Ghosts – or you can wait until the game launches and manage your clan in-game. There will also be clan-versus-clan playlists for multiplayer.

A new free app for clans will aim to make communication and "rallying up" for play sessions easier. The app features a Clan Wars metagame where, depending on which game types you're playing in multiplayer, you'll battle other Ghosts clans in a war of sorts over territory. Placing in the top three of Clan Wars will then yield additional rewards to your clan, both in the app and in the game.

Finally, we've got the minimum system requirements for PC after the break, but first clear up some space on your hard drive. You're going to need it.
