Instead of strafing the Dreadnaughts vertically, you attack from the side. The only one of those editions I have played is the Intellivision version, which flips the script on its side. I originally played The Dreadnaught Factor on my Atari 5200, but there were two additional versions for the Intellivision and the Atari 8-bit computers.

The Dreadnaughts change shape as you play, though, so you cannot always rely on the same runs and strategies which keeps the game fresh. Hitting the vents usually requires you to slow down a bit, but in later stages against ultra-powerful ships, you better clear out the gun protecting the vents first. The only way to ultimately destroy a Dreadnaught, though, is to bomb all of its vents.

Each one you take out decays the ship's velocity. Each Dreadnaught is powered by massive engines. Your ship is equipped with bombs that are key to both slowing down and finally destroying the Dreadnaughts. (Which explains why the game is pretty liberal with awarding extra lives.) The only way to take down the Dreadnaught's offensive weapons is with laser fire. The first few ships offer only minimal resistance, but later levels show no mercy. As you get farther into the game, the Dreadnaughts unleash stronger flurries of fire. Each Dreadnaught is armed to the teeth with cannons and missiles. If the Dreadnaught reaches low orbit, you're helpless to watch the aliens lay waste to home. With each pass, the Dreadnaught drops a little closer to your planet.

You start your run, zooming across a star field to reach the warship. At the start of the game, you see a map screen that shows the Dreadnaught entering orbit.
