How to Get
One obtains the Brickstown Beacon supergroup badge by visiting all the Brickstown exploration badge locations while in supergroup mode.
Note that visiting these locations while not in supergroup mode will not advance towards earning this beacon badge, even though it will earn the personal exploration badge for that marker.
