Clan HQs were added June 11th, 2014 after being one of the most support ideas to be added to the game for years. With this implementation, Clans would be able to compete against each other in weekly competitions, and often marks your clan as being officially established. Clan HQs can be found on the Outpost screen, and be purchased for 10 million dollars. Each HQ holds up to 20 people maximum, and cannot be expanded upon. It's important to note that if you leave a clan HQ within the first 30 days of joining it, you will not be able to join another one until that time period is over.
