The game - Dreadnaught Factor, The - Intellivision | INTV

Your mission is to stop the alien ship before it enters your sector and destroys the Earth. And you are so tiny compared to the huge Imperial ship! 140,000 feet long and weighing 970 mega tons - that's what a colossus will have to endure.

Each subsequent level is similar to each other, except for the number of ships and the speed of the game, so the game gets boring quickly..

It was later ported to the Atari 8-bit and Atari 5200.
