[Shooting around corners]

In a SP, Lone wolf mission hit the black button, that will allow you to move your weapon around freely, click the right thumbstick to zoom into the gun camera.  If you hit the white button while aiming at a target that will call an Airstrike on that location.

Sorry, I did not specify the platform. I'm playing on the ps2. It sounds like you're talking about the xbox.

[Shooting around corners]

I have rented the game from Blockbuster, and of course there is no instruction booklet. I have seen the commercials, and they show one of the ghosts aiming his rifle around a corner with the camera. Is this a feature of the game, and if it is, how the H@#$ do I do it?
