In modifier mode, you have access to four analog modifiers with what where the Dpad buttons. We use these modifiers to directly affect the X and Y-Axis.
With X1 we get the strongest modification of the X-Axis, giving us a slow walk, for example.
With X2 we get a weaker modification of the X-Axis.
Y1 is our strongest modifier for the Y-Axis, and Y2 is a slightly weaker one.
In addition, you can press X1+X2 or Y1+Y2 to get a third modifier for each axis.
By combining these modifiers to any ordinal input (ie, Up+Left, Down+Right, etc), it'll give you a different angle than the typical 45 degrees.
Check out the video above to see what the angles look like.
