First boss fight for Lost Colony expansion DLC. He will fly around the arena on a Gigadesmodus, and cannot be damaged while flying. You will need to destroy all four power poles around the arena while fighting off the creatures that spawn. After you do so, he will land, and you can damage him. Crystals will spawn on the ground, and if you hit them they will explode, stunning the boss and making it easier to fill him with holes. Hope this helps, and happy boss fighting!
