Strategy, speed, tactics - all crucial factors in this all action
space conflict. Every move you make the aliens will counter in an
attempt to prevent you from destroying the weather control station
which you must do in order to win the battle. You will need to plan a
precise tactical campaign and be on your guard at all times - the
aliens are waiting for you to make just one slip up, and you certainly
won't get any second chances!

You have various military units under your control and also radar and
explosive units. Use these carefully as the aliens have their
equivalents which will soon be revealed. If you can manage to destroy
all the aliens units and escape in their space craft all the better,
and all the more points for you.

HUMAN UNITS

Radar Units - When selected R key they will immediately change screen
picture to display the area centred on that radar unit. There are 4
radar units and pressing R cycles between the units in sequence.

Explosive Units - These are nuclear units designed to be exploded with
the E key. To destroy the weather centre you will need to explode two
units side by side. An explosive unit adjacent ta a space ship or a
factory will destroy it, and all units in the surrounding area at the
time of explosion will be severely damaged or destroyed as well.

Hover Infantry - This is a fast and very mobile unit with medium armour
and fire power. It can only attack adjacent units, but it can cross the
acid swamps and minefields which you will come up against.

Hover Armour - The same features as the Hover Infantry but with a long
range attack capability.

Strider - This is a slow moving unit with a medium armour and fire
power. It can only attack adjacent units.

ALIEN UNITS

Heavy Armour - A slow moving unit with heavy armour and heavy fire
power, but some long range attack capability.

Fast Strike - A fast hover unit with low armour and fire power but
with the ability to cross acid swamps and minefields.

Droid - An equal match for the human Hover Armour unit.

GAMEPLAY

Destroying the weather control station is your major objective. To do
this you will have to explode two out of your three explosives units
in adjacent positions next to the weather station. If you manage to do
this you must leave the planet as quickly as possible and with as many
of your units as possible in one of the available space ships. If you
leave the other space ship intact with alien units still on the planet
you will be shot down on take off, so you will have to destroy them
all before you leave or use your remaining explosive unit to destroy
the other space craft.

The aliens can destroy a space craft by placing any 3 units adjacent to
it and ordering them to self destruct. If both space ships and the
weather station are destroyed you can either end the game or fight it
out to the death.

SOME IMPORTANT POINTS

Units can hide in and fire from factory units.

Units can partly repair damage by landing on a full fuel cell. Each
fuel cell can only be used once.

Units can only embark on space craft from the spaces adjacent to the
doors.

Exploding explosive units will destroy all adjacent units (alien and
human) on adjacent squares. If an explosive unit is destroyed by enemy
fire it will explode.

HINTS

Protect your explosive units, you cannot win without them. Be
particularly careful to keep them clear of long range enemy fire.

Watch out for messages on the 'Tele Printer'.

Keep constant watch on all your units, neglect may turn them into
cannon fodder.

Always keep your overall target in mind.

SCORING

At the end of the game you will receive a points score table. High
scores are awarded for destruction of the weather station and the
alien space ship. An even higher score is awarded if you manage to
destroy your own space craft and escape in the alien ship. Points are
also awarded for each alien unit destroyed and each human unit which
escapes from the planet.

CONTROLS

By placing the cursor over a unit and pressing fire a status report
will be displayed in the message window. If current orders are
satisfactory then press fire again. If not move the cursor to a new
target destination and press fire again.

The cursor will automatically move to the next unit in sequence
although you can pass through units with current orders to the next
unoccupied unit by pressing N.

Your units will automatically defend themselves if they are attacked
and will always choose the target to fire at. You cannot select the
target.
