As incredible as it seems, it is best to *keep moving*. While you'll probably feel more comfortable when standing still, you'll surely be an easier target for any object haunting you. Every some period of time, new objects enter the current zone. They may be enemies, as well as various kinds of asteroids, as well as goodies. Try to learn to distinguish between the creation sounds: you'll need to keep updated about what is going around the zone. To destroy the Head Quarters, you'll have to accelerate toward the base and *shoot* a lot. The best weapon to blast those bastards is certainly the triple shot, while the machine-gun shot is more suitable for the Mother Bases. Furthermore, this shot is probably the best for all types of enemies.
Take time to learn how to drive your Inertial-Fighter during first wave, and how to face Bees in the second wave; basically, use these two waves to collect as many goodies as possible.
