Help to shoot

Hello my friends,
Im a newbie. I have downloaded the demo but when i paly i cant shoot.
So what button is the good one to shoot.I have a gamepad Saitek P880
Thanks

I'm not familiar with your controller, but it's the button on the left.


In this case it would be the Blue button.

or if it's a dual analog, you can also use the right analog stick

the X one, I've got myself same controllers

i use 北通 pad
