Alien Disruptor

Beat level 7 on expert mode to get the alien disruptor.

Defeat the Mission 6 Boss

To defeat the boss in Mission 6 easily (the big green plane) make sure you have plenty of the fat
green missiles. Then you want to get underneath the plane and shoot as many upward as possible at a time. Do this a while and he will die easier than trying to get a lock on him. For the other planes,
buy some big red locking bombs and just shoot a shit-load at him.

Level Select

At the "Press Start" screen, press C-Up seven times for level select.

Presidential Bailout

While playing, press Z + C-Up + C-Down, then launch a homing cluster at your opponent. If it hits,you will see the president jump out of the plane.
