GRAV

By Martin Brownlow


Introduction

  In  a strange and  bizarre set of out
of date dimensions, there existed a be-
ing which was totally evil.  
  It had already  conquered all  of the
galaxies and star  systems in  it's own
dimension, and also in two  others, and
it was hungry for more.  Then it  found
it's way into our dimension.
  It  had taken over  two of our  bases
before we even knew it was there, corr-
upting the men that lived there so they
would  serve it.  Now it is  trying for
the Earth.
  You  have been chosen to  attack it's
two bases, and  then hopefully  destroy
it forever.  Your ship is the best that
Earth's  scientist's could  produce and
can teleport into  the very  heart of a
base.

GOOD LUCK.



The Game

  Grav is a 'rotate  and thrust'  game,
similar in concept to  Thrust and Oids.
To complete a level, simply  follow the
instructions in the  mission  briefing.
To complete most levels,you simply need
to destroy all enemy installations.
  There are eleven levels in all, three
are training levels,and the two planets
are four  levels each.  You can attempt
the planets in any order,  but you must
complete both planets to win.


The Options

  When you  have  chosen  which set  of
levels to play, you are presented  with
a menu with four entries,  the first of
which is  INTELLIGENCE.   Choosing this
will take  you to a description of some
of the most common installations.
  MISSION BRIEFING does exactly what it
suggests, as does COMMENCE MISSION. The
final  option is  REVIEW  CRAFT.   This
allows you to alter the craft's charac-
teristics  to suit your taste, and also
add shields and so on.
  The things you can alter are:-
  
IMPACT SHIELDS (1 resource point)
  protects your ship from 1 bullet hit.

SHOT POWER (5 resource points)
  upgrades your bullet strength.

VANE STRENGTH (2 resource points)
  allows faster landings.

ENGINE THRUST (0 resource points)
  allows you to alter the strength of
  your ship's thrusters.

TURN RATE (0 resource points)
  alters the speed of rotation of your
  ship.
