KH2 Gummi Camera

Not sure if this the correct place for this but....

I am creating a game similar to the gummi ship mission in Kingdom Hearts 2 and right now I am getting confused on how they created their camera for those missions. I know its a perspective camera as their is a sense of depth when playing. However using a perspective camera, when you shoot, it looks like going towards the center of the screen yet when you shoot in the gummi mission you are able to shoot towards the corners and sides of the screen/viewport. Anyone have any idea on what they did to pull this off and i apologize if this is unclear/vague

Here is a gameplay video of the gummi missions

 

I think I have figured it out. I just need to add the horizontal value of the stick to a game object so that when I move left/right I rotate the missiles in that direction as well
