It’s confirmed and more details should be given out today: T25 Pilot 1 is going to be a marathon/mission tank, meaning players from the EU Server will be able to get it for free. No information if other servers will get this mission.
Players will have to complete 13 missions in 15 days, but they can only do one mission per day. So it will be one of those missions where you have to login at least 13 days out of the 15. No details yet on what missions players will be asked, but more should be announced today.
