Control emblem now available?
It looks like the "Control" emblem may be available from some content creators as part of the Baron Bingo event. Each creator will have their own bingo card that you can help them with to get the emblem. It appears that each content creator will have a different card and different ways to earn the emblem, so you'll need to check out each person's individual cards for the full details.
