The easiest way to kill the male is to hit the head with the tank bombs. Keep doing this and he will run away. Chase him and defeat him.
When the male calls for help from Spitfires, enable the "Invincibility" code. Get in the small pond that the male circles around. From here you can shoot almost anywhere, and the fireballs that the Spitfires shots cannot hit you.
Dragons Termimus: Easy completion
Power up your spit fire at the beginning. Shoot the very first with some charged fire balls to destroy it, then do the same to the back. The train will then stop. Free the dragons and destroy the rest of the train with your dragon friends.
Fallen Angels: Easy completion
Go straight to the road immediately and follow it until you reach the helicopter. You will be instructed to stay with the convoy but it does not matter. Go there and wait for the convoy to arrive. This may take a while. While you are there, you need to protect yourself from the dragons, however this is easy. When the convoy arrives, you have to protect it. Then, lead them back on the road.

Origin Of The Species: Easy completion
At the beginning of the level, follow the barbed-wire fence on your right until you find a gap in it. Go through the gap. This bypasses the second dragon you normally encounter (the crawling, napalm-spewing one at the gate). When you get closer to the nest-guarding female, you can get a critical hit. It takes out the nest-guarding dragons very easily. You can also use missiles to do this easier.
