All the crystal bases must be destroyed in order to win. You can only lose one Dragonfly from each side — lose both and it’s a bust. Ignore the shadow tanks — they’re not your chief threat. Watch for fighters from all sides, keep your top-down radar at maximum range. You can’t afford to lose more than three Dragonflies — sometimes less — so do what you can to help them. Take the long distance shots to weaken their shields. Protect your buddies.
