Your family has once again been caught by the droids and it is up to you to rescue them.

Given the very non-droid like name of Julian, you are the duelling droid and must find the members of your family who are suffering at the hands of the evil monsters on the planet Zennor.

There are 99 different levels and each is a separate screen.

Once the game has loaded, you start on the first screen. At the top, your score and the number of lives is displayed. A high score feature is also built in so that you can try to beat your record.

The line at the bottom of the screen tells you which wave you are on. There are various objects on the screen at one time, some of which move and some which don't.

The basic idea is to shoot the aliens and try to find the members of your family. These are human-like figures which waddle innocently round the screen looking as though they need rescuing. You simply have to walk in to them to gain the extra points and their eternal gratitude.

The droids are not so friendly. Contact with one of them will result in the instant loss of one of your three lives. Just to make the game harder, not all the evil droids are affected by your laser gun. If you zap them, they'll just get up and walk away.

There are also other objects round the screen which must be avoided.

The joystick will point the droid in eight directions. I found it quite difficult to get it to walk straight at times, though.

Although the graphics aren't up to much, I really enjoyed this game. It's addictive and great fun to play which is what counts, even though I could only manage to reach level six.

Sound is reasonable and I especially liked the stamping of horses' hooves as the droids run towards you.

Duellin' Droid is for one player only and requires a joystick.
