This is very similar to 3D Tunnel, except that the tunnel (or vortex) is defined in multitudes of coloured dots rather than solid blocks, which gives more of a tunnel-like feel. The tunnel also twists and squirms like a mad thing so it's quite a trick to stay safely in the centre of it. On the other hand, the 3D animation of the objects isn't quite so good and there are no skill levels which means it quickly loses interest. There is a long but very amusing intro in the 2-part load. User-defined control keys, so it works with almost any joystick. Good value but limited playability.

STRIKING GRAPHICS CONFUSING

Anyone who has seen 3D Tunnel will find Vortex for the 16K Spectrum familiar. The story is that you are in a spacecraft caught in the gravity well of a giant neutron.

Your job is to fly out of the vortex white firing at the various space monsters attacking you.

The flashing graphics are striking but a little confusing, making scoring difficult. There is also a long and wordy introduction which provides very little helpful information, but fortunately you can go straight to the game without looking at it.

Vortex is available from J K Greye Enterprises, 16 Park Street, Bath, Avon BA1 2TE. It costs £5.95.
