Instructions

Only the quickest can survive in this super-fast 'zap-em' game requiring superior reflexes. The future of the galaxy is in your hands as the ruthless invaders from NGC 891 crash through the ionosphere.       

Starting with just three lives, you must destroy each wave in turn. A life is lost if you are hit by the enemy fire or if the enemy manage to get past your craft. A bonus life is awarded every 100,000 points. Behind the last wave of enemy craft hides the mothership. This must be destroyed so that you may advance to the next level.

A hi-score table records the top eight scores.

Review (ELBUG)

This is a very fast Space Invaders type of game, requiring superior reflexes if you are to prevent the aliens from landing. The game is not that original as computer games go, but worth buying if you like the adrenaline draining 'blast and zap 'em' type of game. Rating: ***

Review (Electron User)

You've seen it all before. The space invaders tramp predictably across the screen, edging relentlessly earthwards. You wipe them out mercilessly with your quick firing laser base, rapidly clearing the first screen. It appears all too easy - then all hell breaks loose...

The second wave doesn't follow a set pattern. They swarm about all over the place setting up defensive boxes. If you don't break them up they will be your downfall. Moving quickly earthwards they have landed before you can gather your shattered wits. And that's only the second wave - there are nine in all, each progressively worse.

POSITRON is a fast moving, colourful and satisfying game. So sharpen your wits, tighten your sweatband and give it a whirl.
