hey guys please help me

Keyboard? Tough luck, unless you have 10 fingers...in one hand.

i now that it's hard,but tell me how to do it

I use a 360 controller.

maybe someone know how to do with keyboard?

its easy, you use the analog stick.....on a controller

this is a 360 ported game, your lucky a keyboard even works on it as well as it does

your only option without a controller is to go in a circle really fast on whatever you have the shot stick mapped to, other than that, go get a controller

It's IMPOSSIBLE to do it with a keyboard, you need an analog controller.

i think that i really must to buy analog
ok guys,thanks for help
