Space Invaders
(VMU style)

Section One : THE GAME

Aliens are invading our solar system and you are earth's only hope.

The aliens use the military tactic of always attacking in waves of eighteen.

If the aliens get to your location, the impact forces you back a sector and removes one layer of your three layered ship.
The aliens rejoice at this and slow down contentedly.

As you lower their number, you enrage them to attack faster and faster.

Each new wave of alien invaders are more and more angry at you for the death you bring to their kind.

But do not feel sorry for these unarmed attackers, for they only wish you and all of earth's inhabitancies harm.


The game will start by showing you the loading screen, after a short delay [PRESS A] appears and you may do so to begin the game.
Failing to press A will result in a short scrolling credit sequence.
Although it has already been preordained, you will only find out weather or not you are playing at night or day once the game begins.
Your ship can be moved left and right as well as firing small anti alien missiles (with explosive tips)
You may launch one missile at a time with the A button
Only if the explosive tip comes into contact with the lower armour of the alien will it be destroyed.
Each alien is worth ten points.
You may review your score at anytime during your battle by pressing B
This information screen can be dismissed with the A button.
Each time you destroy a complete attack wave the score and level information will also be displayed.
Your ship has three protective layers and the aliens take great joy in stripping you of these.
If you lose the last layer you are unfortunately destroyed and the gameover screen is displayed, followed by your final level and score information.
There is no high score table, so that such valuable information may never fall into the wrong hands.
If you make it past level five, congratulate yourself and make secret note of your top score, show it only to those you trust.Alien sympathisers are everywhere.
