Key points of Watch_Dogs - Hotspots
Hotspot
Hotspots that appear on the map, have been marked with a tick. These are the points that, for the player, serve only as the points of information and the history of interesting places however, with the exclusion of the multiplayer mode. It is there that you can become the Mayor of a given point. In order to become one, you need to visit the point, not more often than every hour but, as often, within a week, as possible. It is there that you can receive and leave presents for the other players. Apart from the enumerated aspects, hotspots are required for the completion of the game in 100%, and they unlock the "Geolocated" achievement.
SongSneak
A song that has been intercepted with SongSneak
SongSneak is a smartphone app similar to the real-life ones. If activated, it recognizes the title of the song that plays in the background. It is one of the methods to obtain songs in the game. The places where it is the most effective to use this app are the ones where music is being played all the time - bars, clubs, clothes shops and gun shops, as well as kiosks in the streets. Once you hear a song, start the app and wait for it to be recognized. If you do not have it in your playlist, it is added to your collection. Another method of obtaining songs is hacking, with the Profiler, into the passers-by. From some, instead of their account numbers, you download one of the songs on their playlist. Collecting all of the 23 songs is required to complete the game in 100% and to obtain the "Disk Space Full" achievement.
Note: to collect all of the songs, you need to complete the story mode - some of the songs are unique and they are added after you complete some of the missions.
