First Diamond Division Clan War starts Feb 21st; next regular Clan War starts Feb 19th
Beachhead Studio has announced that the first Diamond Division Clan War for Call of Duty: Ghosts will start February 21st, 2014. It’ll last three days, as it’s the new, highest division available. For more information on Diamond Division, including how to register, click here.
Friday, February 21st through Sunday, February 23rd
Diamond Division wars occur in four-hour periods over three days. When opting in, your Clan leader will have the option to choose from three different time zones indicating when your Clan’s four-hour window begins throughout the weekend.
If your Clan has placed 1st in at least 2 Platinum Division wars, your Clan leader can opt in today via the Clan Wars feature in-app or through the web at https://www.callofduty.com/ghosts/features/clans/diamond. Note that opting into Diamond Division means your Clan will ONLY compete in Diamond Division moving forward, unless your Clan leader chooses to opt out and return to the lower divisions.
For the regular, bronze-platinum clans, the next Clan War starts Feb 19th and ends Feb 24th.
Wednesday, February 19th through Monday, February 24th
In order to run both types of Clan Wars concurrently, we’re pushing the next Bronze – Platinum Clan War back one week. From that point, those Clan Wars will resume every other week, running from Wednesday through Monday with Diamond Division wars running on the weekends.
