Nice one!:up: Shame the graphics for the wheel aren't crash hot. Nice tutorial though and a great way to learn how to use a wizz wheel.

Awesome :up: :know:

It also works, with appropriate changes, with Hitman's KM wheel.

I've been thinking about translating the instructions from using the SACF to using the KM wheel, along with illustrations, but I rarely get the time. When I do get time, I end up playing SHIII until my wife yells at me...

Incidentally, does anyone know a definitive use for the other arm on the KM wheel, the one with a 120 degree arc marked on?

I don't think any one knows for sure at this point, but Hitman had an educated guess that it was used to help figure an intercept course.

Is there some idea how that would work in practice?
