Take control of an alien Xyloxi creature and help it collect all the crystal cores in the nebula. Beware of the Mithri Leeches who will try to devour the Xyloxi - trick them into crashing into each other! Collecting the crystal cores will also provide your Xyloxi with temporary defenses. Safeguard the nebula against the Mithri invasion by defeating the 3 Mithri bosses.
