All highspeed movement now requires a "Double Tap" in order to swoop. Simply tap any direction (up,down,left,right,forward,backward) twice and hold down the directonal key on the second instance. You may "chain swoop" by double tapping in a different direction while still holding your last direction to make a fluid, yet sudden change in direction.
There is no longer a need to target opponents, swooping is free form 360 degree movement.
