Collectible Locations Map
Hint Collectible Locations
There are 50 Hint Collectibles scattered around the city. Each collectible appears as a pink orb in the world. Each time an orb is collected, a random hint will appear in a pop-up onscreen. Each hint is recorded under Hints in the Logs section of the pause menu.
Picking up a Hint Collectible yields some EP; the EP-worth of each Hint Collectible increases as each time a set amount has been collected.
Gathering all 50 Hint Collectibles unlocks the 'Polymath' achievement/trophy.
You can see hint images for all 50 of the collectible locations spotted on the above maps on the following page.
