Commodore's cartridges are now a much better buy as the price has plummeted to what I call a "reasonable" level - though I notice some shops are still asking a much higher price.

Avenger is a classic 'space invader' game with little to distinguish it from other versions unless you happen to take a liking to the shapes of Avenger's aliens. The black background makes the graphics a bit murky but you can always give the brightness control on your TV set a twist.

As always with Commodore products, the packaging is superb; and I can't fault the strength of the program itself. It does everything you would expect. If you must have an Invaders-style game on a silicon chip then at this price (£9.95), you can't grumble.
