We have observed a new passcode format in the Body in Brooklyn. A Cover-Up? post on June 16 2016.
The new passcode format is:
x are any letter from
# are numbers
keyword is a word related to Ingress (our compiled list of keywords)
At this time, we are not sure if this code will be used exclusively for daily codes from the Investigation Blog or will it be expanded to include Word of the Day and Ingress Report codes.
