Here's a trophy guide for Payday: The Heist that requires excellent teamwork. To get the 'No Photos' trophy, you'll need to take out all of the security cameras in the level First World Bank within ten seconds of drawing your weapon.
This one took several tries for me, mainly because it's hard to depend on random people on the internet to do anything. But if you team up with a good set of players that really want to bring teamwork to the forefront of this game (as it should be played), this is an easy one.
