Vanguard [Model CX2669]

* FIRING SLOWS YOU DOWN. Your spaceship moves twice as fast when you aren't firing. Hold your fire when you're passing barriers or diving for energy pods.

* MISTS AND HARLEYS. Keep the spaceship moving up and down to avoid missiles and lay down a barrage of lasers vertically, against the enemy's line of flight. A Mist can only fire once, so you can dodge its missile and then go for it.

* HELMS AND AMMOS. Try to hit these with your starboard and port lasers before they cross your path. Avoid getting caught between two balloons, since it is hard to fire without moving into them.

* KEMLUS AND ROMEDAS. Fire horizontally across their line of flight.

* STRIPPED ZONE. Don't try to shoot everything you pass; think mainly of surviving. Fire at barriers and Garimes through crevices in the rocks, but take care not to crash into the rocks. Don't fire at Paynes. You can't destroy them, and firing slows you down when you need a burst of speed to pass safely.

* CITY OF MYSTERY. If you want to earn lots of points, hold your fire until the last minute. The trick of course, is to dodge the missiles. Gond aims directly at you, so keep moving. As soon as you enter the city, move up to avoid the first missile. When it passes, move down. Keep changing your position until you run out of room, then fire.
