Hello, and welcome to my Achievement/Trophy Guide for Watch_Dogs. Below you'll find every Achievement/Trophy, how to obtain them, and YouTube video walkthroughs for the more difficult ones.
I hope these help and good luck out there!

Who Is Raymond Kenney?: Complete Act 2 - Complete this one by going through the story
One Down, One to Go: Complete Act 3 - Complete this one by going through the story
Hard Crash: Perform 10 vehicle take downs - Vehicle take downs happen when you wreck an enemy vehicle using a road hazard. Be it a traffic light, a bridge, or a blocker. Perform 10 of these to win!
Communication Fail: Using non-lethal takedown, stop 10 civilians from calling to report you - When a civilian decides to be a snitch, simply walk up to them and perform a 'takedown' (B on Xbox, Circle on PS). This will grab their phone and smash it rather than kill them. Can be achieved simultaneously during "Hardware Fail" if you play it right.
Power Cycle: Participate in 5 different City Games
Magic Smoke: Kill 4 enemies within a single instance of Focus - This one is best done by killing cops. Shoot around a bit in town until someone calls them. Once they arrive, wait until they get out of their cars, hit Focus, and kill at least 4 before your Focus runs out.
Hardware Fail: Shoot out a tire on 15 different vehicles - Easiest way to do this one is to simply line up 15 random cars and shoot their tires out. You can also get the Achievement "Communication Fail" during this if enough people call 911 and you non-lethally remove their phones.
