Take control of an alien Xyloxi creature and help it to 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.
