The Dreadnaught Factor

The player flies a small fighter spacecraft to attack a dreadnaught, a large and heavily armed vessel. Each dreadnaught approaches the "Galactic Unstable Energy Field", which acts as a defensive line. The goal is to destroy or disable each dreadnaught before it can reach the Energy Field and launch its missiles to destroy a planet the player is entrusted with defending.

As the game progresses, the player can make repeated passes over the dreadnaught, one fighter at a time, attempting to weaken its defenses, slow its progress, and finally destroy it. The fighter is equipped with lasers and bombs to attack different targets. Bombing the dreadnaught's engines slows its progress, while shooting out its bridges reduces its ability to return fire from any intact gun turrets. In addition, each dreadnaught has five missile silos; if all of these are destroyed, it will be unable to attack the planet once it is in range. The dreadnaught advances toward the planet once the fighter has either flown its entire length or been destroyed.

A December 1983 review in Joystik magazine awarded the game four stars and called it "a sure winner".
