Well , bret , there's an option in the bullet behavior options ( DUH ! )
That let's you disable this behavior ( Not the bullet behavior , the behavior of taking the object angle as an angle of motion ) you can set it to no and then you can controls the angle of motion with the action
"Set Angle of Motion"
Works very well , I remember ol' days when C2 was a new born :P
Didn't have those fancy options :D
Oh well , cheers ...
