To get this achievement, you'll need to raise your Notoriety to 100. This can be be spread across multiple missions.
Complete missions, but be sloppy. That is, leave lots of witnesses, get caught on tape, and make a lot of noise.
Keep in mind that you'll probably need to start a new career for this one, as any missions you complete retain your best notoriety on subsequent playthroughs.
Also, don't try this on the Rookie, as Notoriety is not taken into account.
I had fun doing this one last, right after finishing the story on Professional. It was fun to just run around guns blazing like an idiot after spending all that time being stealthy.
