Watch Dogs ctOS Towers Locations
There are 13 ctOS Towers in Watch Dogs that you need to unlock as a necessary prerequisite for attaining 100% game completion.
None of these collectibles is missable and are marked on the map since the beginning of the game. Unlocking these towers is a good idea as they reveal the locations of other collectibles and unlock Fast Travel locations.
Furthermore, finding and unlocking them will unlock SMG-11 weapon and Amargosa Turbo vehicle along with Clear Signals Achievement/Trophy.
Unlocking almost each one of these ctOS Towers requires you to do a bit of climbing on the rooftops. And like various missions in the campaign mode, you will have to go through a series of CCTV cameras to reach your desired location.
Also expect resistance from Blume Officials who will do everything in their power to put you down.
As the story will unfold, you will be required to unlock some of these towers. The rest can be done with our guide below. Note that you don’t have to unlock all of them in order to complete the story, but it is recommended nonetheless.
