Microsoft has today sent out emails to long term Xbox Live Subscribers which offers a free Xbox One console or the game Killer Instinct with all unlocked characters. We received an email no doubt as a result of our high gamer score and 9 year tenure, although it’s not clear whether those being offered Xbox Ones is as a result of a random process or something else. Either way, if you do receive an email from Xbox@engage then it’s legitimate and means you got something for free for your loyalty to Xbox.
