How this card plays
Two wings open and close in a V while the outer members fire in alternating volleys. Choose a safe flank before the next wing attacks. The first warning introduces Beat Volley. Later volleys alternate between that signature and the formation pattern. Survive three waves to earn a clean clear, or take one free assisted clear.
