GZPD is an AR simulation campaign that empowers its participants to role play as special police to maintain stability. It aims at discussing civil rights, public power on administration, and the balance between privacy and public security by allowing players to reassess how ubiquitous surveillance impact daily life.

The campaign enables players to get a full picture of the stability system by experiencing how police use their positions and public big data system to fulfil missions like patrolling, arresting, and maintaining stability on real sites.
