The Game

You are in command of the only defences on the Red Planet. The screen display represents the view through the sights in the cramped confines of the solitary laser post.

You must sweep the skies above the domed city to protect it against the invading Zargons. These soar over the barren terrain from your left on regular sorties. Line each ship in the centre of your sights, or slightly ahead of it and fire. Those that you miss will now come from the right, but don't forget that another ship will be coming from the left at the same time!

As they fly over they issue a barrage of shells from their under-bellies onto the city below. Activate the forcefield to deflect their missiles, but exercise caution as energy is limited. Given time the energy banks will recharge fully, but time is not on your side!

There are three types of enemy craft altogether, each with a different flight pattern.
