    Version History
    1.0  - Completed the list of machine locations. (11/18/2004)
    0.91 - Added the rather important discovery that damage could be repaired by
           touching large white spheres.  Also confirmed that attraction/repulsion
           and number of on-screen objects increase with score. (11/17/2004)

    DUALITY is one of several video games embedded in GRAND THEFT AUTO: SAN
    ANDREAS.  Its basic mechanics are similar to the old Atari arcade game
    ASTEROIDS, but with a few twists - most notably the ability to go for either a
    "white score" or a "black score", for which there are separate high score
    In DUALITY you pilot a ship in open space, controlling your movement with
    rotation and thrust.  Large and small spheres of white and black are spread
    about you randomly.  The large white spheres repel you while the large black
    spheres attract you.  Small spheres have no effect on your course.  You can
    pick up small spheres and shoot large spheres, but touching large black spheres
    will damage you.  (Touching large white spheres will heal you, but that's
    easier said than done.)  The goal is to get the highest score possible before
    you take enough damage to be destroyed.
    2. DISPLAY
    There are two meters in the lower left part of the screen:
    Damage Meter (RED):  The red meter shows the amount of damage you can take.
    Damage is caused by contact with large black spheres, and can be repaired by
    contact with large white spheres.  Once the damage meter is empty your game is
    Thrust Meter (GREEN):  The green meter shows the amount of thrust fuel you have
    left.  This meter replenishes slowly on its own, and will automatically
    replenish by 25% each time you pick up a small sphere of either color.  If the
    thrust meter is empty you won't completely lose thrust, but your thrust will
    become much weaker until you replenish your fuel.
    Your score is displayed at the top of the screen.  This can either be a "white
    score" or a "black score" depending on your actions in the game.  The type of
    score is reflected in the color of the numbers.
    When you begin your game, you should decide whether to go for a white score or
    a black score, because this will define your overall approach.  Basically, you
    want to run over the small spheres that are the same color as your score while
    shooting the large spheres that are the opposite color of your score.  (Small
    spheres cannot be shot.)
    To navigate, rotate your ship with the analog stick and thrust with X.  To
    shoot, press O.  Shots will keep moving regardless of how many large spheres
    they hit and destroy, and they'll even continue off-screen for a bit, so be
    sure to fire with care.  If you don't, you'll wind up hurting your score by
    destroying spheres you didn't mean to hit.
    Scoring is determined as follows:
    Large Black Sphere: +10 white or -10 black points if shot
    Large White Sphere: -10 white or +10 black points if shot
    Small Black Sphere: -5 white or +5 black points if picked up
    Small White Sphere: +5 white or -5 black points if picked up
    Firing your gun will take away 1 white point for each shot, but if your score
    is black or zero then you can fire your gun without a score penalty.
    If you have a low score and incur a penalty that would make your score
    negative, your negative score will become a positive score of the opposite
    color.  For example, if you have a black score of 7 and you shoot a large black
    sphere, you will then have a white score of 3.  This is usually only an issue
    at the very beginning of the game.
    As your score increases, the attraction and repulsion of large spheres will
    also increase, as will the number of spheres appearing on screen.  This is a
    very gradual effect, though, so you may not notice until you've been playing
    for a while.
    Since large black spheres are the only objects in the game that can damage you,
    it's easier to get a high white score than a high black score because you'll
    need to shoot the large black spheres from time to time in order to stay alive.
    With that in mind, here are some tips:
    WHITE SCORE:  Pick up small white spheres.  Shoot large black spheres.  Avoid
    small black spheres and try not to shoot any large white spheres.  If you see
    yourself drifting off course, a large black sphere is probably tugging at you,
    so be ready to destroy it - but since you lose one point for each shot, keep
    your firing to a minimum and make those shots count.  
    BLACK SCORE:  Pick up small black spheres.  Shoot large white spheres (though
    not right away, since they don't pose a threat and you may be able to use them
    to repair damage).  Avoid small white spheres and especially large black
    spheres.  Also avoid shooting the large black spheres if possible, but don't be
    afraid to destroy one if you're in danger of hitting it.  You can always make
    up the 10 points you'll lose if you shoot one, but it's much more difficult to
    repair the damage you'll take if you hit one.  Black scores have no shooting
    penalty, so fire all you want as long as you're not hitting any large black
    spheres that aren't threatening you.
    Regardless of which type of score you're pursuing, you'll need to keep yourself
    healthy to stay in the game.  Since occasional contact with large black spheres
    is inevitable, you'll need to repair that damage at every opportunity by
    finding ways to touch large white spheres.  These spheres repel you strongly
    enough that conventional thrust isn't enough - you'll need to use the
    attraction or repulsion of other large spheres in combination with your thrust
    in order to get close enough to make contact.
    The safest and perhaps easiest way to do this is when you come across two large
    white spheres that are about a screen's width apart.  After you've eliminated
    any large black spheres in the area, position yourself right between the two
    white spheres and thrust directly at one of them.  When its repulsion field
    slows you to a stop, quickly turn around and thrust directly at the other
    sphere.  The combination of your thrust and the repulsion of the first sphere
    should get you moving fast enough to defeat the repulsion of the second sphere
    and make contact.  The longer you maintain contact, the more damage you'll
    Another way to do this is to slingshot around a large black sphere while
    thrusting toward the large white sphere.  This is much more difficult because
    of the aiming issues involved, as well as the danger of hitting the black
    sphere in the process.  Sometimes a large black sphere will overlap a large
    white sphere, though, and you can often exploit this.  If you approach from the
    side on which the black sphere is most prominent and thrust directly at the
    pair of spheres, you can pass over the black sphere and slow to a crawl over
    the white sphere.  The initial contact with the black sphere will cause some
    damage, but the brief hovering over the white sphere will usually repair more
    damage than you received.
    One last tip:  Slow down.  There's no time limit, so haste isn't required - and
    the easiest way to get into trouble is to be moving too quickly to react to the
    sudden appearance of a clump of large black spheres.  Also, the more slowly you
    move, the more likely you are to notice the pull of black spheres that may be
    lurking just off-screen.
