Friends and squadrons
You add a friend by swapping friend codes, and both of you must say yes. Only swap codes with people you know. There is no chat.
You can see when friends are online or playing, join them in their game, and send a wave from their card or their coop, one per friend a day. You can remove a friend at any time.
From January 2027 you can join one of the CGSF Academy's four squadrons. Every game you finish helps your squadron that week, and everyone who played for the winning squadron gets 30 Credits. You can change squadron once a season. Your runs count for your squadron once you have been here a week and have 100 XP.
