The award of the Tourist badge would give you a costume power that... makes you look like a tourist, The only way you can travel around is by walking and pausing to take photos occasionally. While wearing this disguise you can be almost immune to residents of the zone you are in, but if you change back to your normal outfit there's a chance you get ganked by the local mobs because you're obviously a spy.
