You have to get through all the enemies defenses to collect the two crystals, which will give you enough power to destroy the enemies base. But the enemies are fierce and they have constructed a bomb at the end that you have to destroy without being nuked. The nuke bomb is a strong trap that if is shot being too close to it, it may destroy those who try to collect the crystals. Beware the rocket launcher the enemies have constructed to stop crystal hunters from collecting their crystals. So get out there and retrieve those crystals!
