Group Attack

When launching an attack, there will be an option on your Fleet page called "Formation". If one is to click this, they will be given the option to send invites to themselves, their buddies, and their alliance. Anyone that accepts the message in their inbox will join in for the group attack.

If a invited party is further away than you, this will delay the time of the attack until the late arriving party would arrive. It is believed that anyone who would cause a delay of more than 30% of the original take will not be able to join.
