Soldner-X 2: Final Prototype

You will need to collect at least 4 keys in all six of the previous stages to unlock Stage 7. The boss requires precise flying with your ship and efficient use of your special attacks. During Phase 1, six domes will appear at the end of spikes that you'll need to hit. This is an area that gets EXTREMELY cluttered with bullet fire and is a perfect time for your limit attack. During Phase 2 the spikes close in and shift, requiring you to maneuver quickly through thin passages to the eye. Use your shockwave as soon as you reach him, and pound away as much as you can. If you have the flame weapon from the third ship, you can finish this phase in one cycle. You'll usually need two. Phase 3 is the easiest, consisting of generally blowing up each of the six spikes while homing rockets are fired at you. Take care to destroy them before they reach you, and the spikes will take care of themselves.
