How this card plays
Guards surround a core that alternates between protected and exposed. Survive directed fire, clear guards and use the opening window. The first warning introduces Glide Gate. Later volleys alternate between that signature and the formation pattern. Survive three waves to earn a clean clear, or take one free assisted clear.
