For this event an Endgame badge was announced. This was given both in Pasadena and In Hannover for Ingress players.
The players in Hannover were given a challenge to solve that would give them both a Stella badge and an invite to Endgame
The solve was to do a circle with letters around the lines given with A at the top (noon). this would give the word saboteur.
Players could then submit this answer for a badge and a place in the beta list.
