Super Invaders
==============

Introduction
------------
You are being bombarded by waves of invading aliens. The
only way to resist invasion and avoid subsequent annihilation
is to destroy the aliens before they land.

You have three Defenders, whose hyper-velocity missiles will
instantly vaporise their target on impact. The Defenders can
shelter from the onslaught behind four bastions, although
even these cannot survive indefinitely.

The alien attacks can vary in their ferocity. Sometimes, you
may only have a "mild encounter"; alternatively, you may find
yourself in an "uncomfortable situation", where a faster
moving enemy releases a deadlier barrage of bombs. The worst
is yet to come with the "terrifying experience", where, in
addition to all the other hazards the bombs have a homing
capacity and steer themselves towards your defender.

The game includes high score, and is fully compatible with
either keyboard or joysticks.



The Game
--------
Select your level of difficulty, choosing between:

1. A "mild encounter" - in which you fend off the aliens as 
best you can, shooting them with your missiles.

2. An "uncomfortable situation" - watch out for the
reconnaissance ship since, if not destroyed, this can 
produce a force shield that guides the aliens and hastens
their advance.

3. A "terrifying experience" - in addition to all the other
hazards, the bombs have a homing capability and steer
themselves towards your defender.



Game Controls
-------------
Z - Left, X - Right, RETURN - Fires missiles



Joysticks
---------
Either joystick can be selected by pressing its fire button
whenever you are invited to press the Space Bar. At the end
of a game, the Fire button can be used to return to the
"level of difficulty" selection page. Pressing the Fire
button here will start the game off keeping the previous level
of difficulty. (If this is done before playing the first game,
the level of difficulty is automatically set to "mild
encounter"). You may use the keyboard controls having already
selected Joystick control provided the Joystick in use is 
left with the stick in the centre position.



Scores
------
An extra defender is obtained at 5,000 and 15,000 points.

A missile is displayed below the line each time a complete
wave of aliens is destroyed.

Three High-scores are maintained; one for each level of 
difficulty.
