Hidden throughout the streets of Gotham City are several tags that Anarky uses to communicate with his men for a plot to rid Gotham of its corruption. Anarky Tags provide a fun little side-quest scavenger hunt that tempt you with exploring the nooks and crannies of Gotham.
Invisible to the plain eye, you must be in "Detective Mode" to spot the various Anarky Tags hidden around the city. Be sure to keep this mode active when searching for them as they can be spotted from quite far away.
There are a total of 24 Anarky Tags spread throughout Gotham City with two achievements assocated with them. Discovering 20 Anarky Tags will unlock the Voice of the People achievement, while finding all 24 will unlock the First Riddle Trophy achievement.
