How to Get the 'But How?' and 'Cheney?' Trophies in Payday: The Heist

The easiest way to get these two trophies in Payday: The Heist is to load up the map Slaughterhouse. Now, to get the 'But How?' trophy, you have to let the armored car fall into the building by itself. But how? Well, after the armored car gets knocked onto the roof the building, just let it sit there. Do not shoot the support cables. If you survive two waves of enemies coming in to get you, the car will fall by itself.

'Cheney?' is a little easier than 'But How?', however. All you have to do is take down a Bulldozer, one of the heavily armored SWAT guys, using nothing but a shotgun. It takes a while to defeat him, so keep moving and use all the cover you can find.
