Key points of Watch_Dogs - ctOS Breach
ctOS Breach - location of antenas beginning quests.
ctOS Breach are another category of collectibles in Watch_Dogs. They appear on the map after you have unlocked the ctOS towers and they are required to complete the game in 100%. Completing each one of the challenges unlocks a series of recordings that tells a separate story, connected loosely with the storyline. It is a good idea to collect them, because each of the missions that you complete provides you with another 250 experience points. Also, completing them is a good way to test your parkour skills and acute eye. There are 16 breaches available in the game.
One of the ctOS antennas
The missions require quite a perceptiveness and swiftness of the player. You start the challenge after you hack into the antenna, high above, in the given point on the map. Then, there appear points in which there are four more antennas, which you need to hack into, within the allotted time. The order is up to you but, often only one antenna is available at arm's length, the other ones may be hidden behind objects, on rooftops. If you fail to complete the mission, each time you can try again, but you need to hack into all of the relays by starting over, from the starting point. Below, you can find all locations of the antennas described, alongside with screenshots that depict their exact locations.
