How to do a Fake Shot & Fake Shot Speed Boost
A normal fake shot involves you loading up your shot (B or Circle) and then cancelling it by tapping pass (A or X).
But to get the ridiculous speed boost, you have to hold LB/L1 while you do this, and then you have to pick an exit direction with LS.
So the final command looks like:
Xbox – hold LB, hold and let go B, quickly tap A, choose exit with LS.
PlayStation – hold L1, hold and let go Circle, quickly tap X, choose exit with LS.
The most important thing to note is that the fake shoot buttons must be pressed quickly to get this to work.
