Res 4 cant be used with as you press A to shoot, can it be used with umbrella chronicles? Thats all I want to know basically.

I'm not sure I remember but i think you use B to shoot in Umbrella Chronicles.

There are several control schemes, but both the default and the zapper scheme use B to shoot. I'm not sure about the third scheme,

You can use A to shoot in UC

I hired it a few weeks ago and from memory, the default fire button is B, but I think you can change the controls. :)
