In a global mission, players around the world all work together to try and meet some specific goal. To enter a global mission, players must connect their Pokémon Sun or Moon game to their Pokémon Global Link account using their Game Sync ID (which can be obtained from the Festival Plaza PC), then talk to the woman next to the PC in Festival Plaza to register for the mission.
In this mission, players must try to catch a total of 100 million Pokémon before December 13, 2016. If the goal is met, every participant will receive 1,000 Festival Coins as a reward. If the goal isn't met, all participants will still receive a participation prize of 100 Festival Coins. Players must use Game Sync before December 13 for their contribution to be included.
