Prior to that, a new battlefield will open up and bring with it a number of tweaks relative to the existing battlefields. First and foremost, any player of any level can participate. The victors will receive a reward buff that affects their entire faction; conquering the battlefield involves holding the capture point for five minutes if you're on the attacking team. The defenders, on the other hand, have to stand their ground for 20 minutes.
ALT1 remains mum on the new October content for now, but the battlefield updates went live yesterday. We'll keep you updated with fresh information as it's released.
