How to unlock the Greedy Fly achievement in Gunstar Heroes - Definitive Guide
After a few passes like this the boss will fly down and launch a triple beam attack that rotates around the screen. You can avoid this by walking around and using the ledges to the right to jump up on top of the boss (this won't hurt you) and just move around in a circle along with the beams as they move until the boss is defeated.
Using the above it's possible to take no damage on this boss easily enough (as you'll be looking to save as much health as possible for the final encounter).
Get some fire in before he flies up and wait for the Gambits to come down. These are spheres that fire a layer of fire in one place, so dodge them as they come down. They will either come down so they create a maze you have to wonder through (if this is the case identify this early on to enter and make your way through, if you get stuck at the side you will get burned) or come down in random fragments, which must be dodged or shot at to destroy. Now Black will do Shadow Hurricane which are three lasers revolving in a clockwise fashion. Use the platforms to the left side to head up and avoid the laser and jump across the boss itself to the other side and drop down underneath, and repeat, firing at the boss all the while. He'll just do this until he's a beaten.
