    Welcome to my FAQ for Centipede.  Since the game is just a shooter that goes
    until all your men are killed, there is no walkthrough per se.  Instead it will
    be broken up into the game itself, strategies for survival, and some in-
    teresting quirks in the game.  Input is appreciated along with constructive
    criticism.  If you wish to e-mail me thoughts on this FAQ, better ways of doing
    things, other strategies, etc., feel free.  Make sure you put Centipede as the
    subject.  If you don't, I'm liable to discard the e-mail as spam.

    | 5.  OVERVIEW |===============================================================
    +==============+
    
    By the 1980's, Atari started to lose the dominating position it once held in
    the arcade market.  Companies such as Taito, Namco, Cinematronics, and Midway
    were just a few of the companies also putting out arcade games.  With this
    "glut" of arcade machines, it wasn't much of a surprise that Atari was starting
    to lose its market share.  Atari, however, wasn't down and out.  It had many a
    trick up its sleeve and it was now using them.  They first developed the first
    arcade flight simulator with Red Baron.  Later, they came out with Battlezone
    (probably one of Atari's most popular titles).  The latter two games were some
    of the first vector three-dimensional games put out.  Atari would later on be
    the first to develop the filled polygon games.  Overall, the arcade market was
    basically space or military shooters of some type.  Enter one of the female
    programmers at Atari, Donna Baily.  In a market dominated by males, Donna
    designed a game (the first arcade game by a woman) that put Atari back on the
    map.  Centipede became a runaway success.  The gameplay basically had the
    player destroying bugs and fungus on the screen while trying to stay alive.
    The fast paced nature of the game endeared it so well to players, it became one
    of Atari's biggest selling arcade games ever.  Good luck surviving the bug
    invasion.

    | 6.  THE GAME |===============================================================
    +==============+
    
    Centipede is a two-dimensional shooter.  You use your shooter to take out the
    insects and the mushrooms.  Your job won't be easy, though, since you will have
    to deal with multiple enemies.  In addition, each of these enemies has a
    certain pattern of attack that you must know to successfully get through each
    wave.  Your dream of being an exterminator is now a reality.

    / 6.1  The Controls /__________________________________________________________
    --------------------
    
    In order to become a master of this game, you must be familiar with the
    controls.  The controls are pretty easy to work.  You just have to play the
    game some to get used to them.
    
    -  An optical track-ball
    
    -  A fire button

    / 6.2  The Playing Field /_____________________________________________________
    -------------------------
    
    The playing field consists of your shooter and all the different enemies.  The
    screens change color with each wave.  I have included an example of what the
    playing field looks like (a little larger then normal):

    / 6.3  Scoring /_______________________________________________________________
    ---------------
    
    Scoring in this game is pretty simple:
    
    Centipede (Body)  :     10 points
    Centipede (Head)  :    100 points
    Spider            :    300, 600, 900 points (Points increase the closer the
                                                 Spider is to the player's Shooter
                                                 when shot)
    Flea              :    200 points (Takes two hits.  First hit speeds it up,
                                       second hit destroys it)
    Scorpion          :  1,000 points
    Mushrooms         :      1 point (Takes four hits to destroy)
    Poisoned Mushrooms:      5 points (Takes four hits to destroy)
    
    You start the game with 2, 3, 4, or 5 Shooters.
    
    Depending on the machine set up, you will earn a free Shooter at the following
    scores:
    
    Every 10,000 points
    Every 12,000 points
    Every 15,000 points
    Every 20,000 points

    | 7.  PLAYING THE GAME |=======================================================
    +======================+
    
    When you start the game, you will be put in the middle at the bottom of the
    screen.  You have an area five mushrooms high (about a fifth of the playing
    area) to maneuver your shooter in.  The game will start when the centipede
    enters the screen.
    
    -  Know your enemies:  This is the single most important aspect of this game.
       If you don't know how each of the enemies behave, you won't last long.  The
       enemies are:
    
       -  Centipede (Body and Head):  Goes back and forth across the screen.  Will
          drop to the next level when it encounters a mushroom or the side of the
          game field.  It will go all the way to the bottom when it hits a poisoned
          mushroom.
    
       -  Spider:  These appear from the top left or right of the player area.
          They will either bounce across the player's area at 45 degree angles or
          bounce in at a 45 degree angle, bounce up and down a couple of times, go
          to the middle at a 45 degree angle, bounce up and down a couple of times,
          then finally go to the right side (at a 45 degree angle), bounce up and
          down, then exit the area.  They destroy mushrooms they cross over.
    
       -  Flea:  These appear in wave 2.  They will appear when you have cleared
          out most of the mushrooms in the player area.  These never appear when
          you have an eleven segmented Centipede.
    
       -  Scorpion:  These appear in wave 3.  They go across the screen and poison
          all the mushrooms in their path.
    
    -  The Centipede will start out as a head and eleven body segments on wave one.
       Wave 2 will be a head with ten body segments and a head that enters from the
       opposite side.  Wave 3 will be a head with nine body segments and two heads
       that enter from opposite sides.  This progression keeps going until wave 12
       when all that enter the screen are heads.  The progression then works back-
       wards for 12 waves, then starts back up again in a never ending cycle.
    
    -  Shooting the Centipede can have two effects:
    
       -  If you shoot the head, then that part turns into a mushroom and the next
          segment becomes the new head and the Centipede will travel in the
          opposite direction (since it hit the new mushroom created).
    
       -  If you shoot the middle of the body, then the segment hit will become a
          mushroom.  The old Centipede will continue in the same direction.  The
          new Centipede will develop a head at the next segment after the break and
          head off in the opposite direction.
    
    -  A good strategy to ensure you destroy the Centipede's in one stroke and to
       keep the Fleas at bay is to create "mushroom corridors".  Mushroom corridors
       are basically corridors between two rows of mushrooms where you can funnel
       the Centipede down and destroy it when it is moving head-first at your
       shooter.
    
    -  A good defense against the Flea is to keep a certain amount of mushrooms on
       the screen.  There is no hard set value but when the Fleas don't come down,
       you have enough.  This number gets higher as your score increases.
    
    -  Speaking of score, Fleas start traveling faster after 60,000 points.
    
    -  Watch out for the Spiders.  They enter at either the top or bottom corners.
       Your shooter may be in the way if this happens.  In addition to collisions,
       the Spiders wipe out all mushrooms that are in its path.  This can create
       problems when you are creating mushroom corridors.  It can also cause the
       Fleas to appear since you won't have many mushrooms in the player area.  In
       later waves, multiple Spiders may appear in the player area.
    
    -  Keep track of where the Scorpions move across the screen.  As soon as the
       Centipede hits a poisoned mushroom, it will immediately head for the bottom
       of the screen.  The only way to stop this headlong plunge is to shoot it in
       the head.  In the later waves, it is not uncommon to have multiple Scorpions
       going across the screen.  They also provide the most points in the game.
    
    -  If you get unlucky and let the Centipede into your area, you need to destroy
       it before it gets to the top of the player area.  Once it reaches the top,
       it will descend again.  If it does reach the top of the player area, another
       head will come out from the opposite side to start its back and forth march
       across the screen.  This will continue until you destroy all the Centipede
       parts in the player area or until your Shooter is destroyed.  Of course, if
       you are trying the tricks from Chapter 8, then disregard this.
    
    -  If your Shooter gets destroyed, all partially shot up mushrooms are re-
       generated and you start at the beginning of the wave you got killed on.
    
    -  Depending on machine set up, all enemies (except the Centipede and Flea)
       speed up at the 1,000 or 5,000 point mark.
    
    +============+
    | 8.  TRICKS |=================================================================
    +============+
    
    There are a couple of tricks in Centipede that will allow you to rack up a lot
    of points.  The key to doing these tricks is to do precision shooting because
    you will be using the mushrooms created by the destroyed Centipede pieces to
    trap the Centipede.
    
     ___________________________
    / 8.1  Bottom Side Tunnels /___________________________________________________
    ---------------------------
    
    To perform this trick, you must do the following:
    
    -  When the Centipede is one row over the player's area (fifth mushroom up), go
       to the opposite side that the Centipede is on.
    
    -  When the Centipede turns around, it will be in the player's area.  It then
       will make it to the side you are on.  Right when it hits the side of the
       screen and turns around, shoot it.  This creates a mushroom and forces the
       Centipede to turn around and go down one level.
    
    -  Again, after the Centipede hits the wall, shoot it, create a mushroom, and
       force it down another level.
    
    -  Continue to do this until you have only the bottom part left.  There are two
       ways to do this:
    
       -  If you get killed by the Centipede, this will also create a mushroom and
          you will have a vertical line of mushrooms along one of the side.
    
       -  If you are quick, you can pick off the Centipede and create this last
          mushroom.
    
    -  Repeat this for the other side.
    
    -  Regardless of how you create this "Side Tunnel", you will now have a trapped
       Centipede since the only thing it can do is go up and down within the
       player's area.  New heads that come out will also be trapped.
    
    -  Now you can pick off enemies at your leisure.  The only enemy you need to
       make sure you take out is the Spider since it can wipe out part of your
       "Side Tunnel".
    
    -  Good players consider this "cheating" since it basically lets the player
       have free reign over the game.
    
    -  When you have completed your task, you should have something that looks like
       this:

    / 8.2  Central Tunnel /________________________________________________________
    ----------------------
    
    This trick works along the same line as the Bottom Side Tunnel trick.  The
    difference is that you create a tunnel down the center of the screen.
    
    -  When the Centipede starts its descent, hit it.  This will cause it to
       reverse direction after hitting the new mushroom.
    
    -  After going one or two mushroom lengths, hit it.  Again, this will cause it
       to reverse direction.
    
    -  Continue to do this until you have built a "tunnel" that touches the
       player's area.
    
    -  Also make sure you build up mushrooms to the left and right of the tunnel
       to prevent the Fleas from coming down and depositing their random mushrooms.
    
    -  From this point on, when the Centipede approaches your tunnel, all it will
       take is one hit to force it to descend.  In a sense, you are causing the
       same effect that a Scorpion causes, but on your terms.
    
    -  Since you are keeping the top left and right areas clear, it should take a
       longer time for the individual heads to make it to the player's area.
    
    -  It will take a few waves to build up your areas.  Once built up, you should
       be the master of the game.
    
    -  As for the other tunnel, make sure you take care of the Spiders when they
       first enter so they don't do any damage to your "Central Tunnel".
    
    -  Also make sure that you keep your tunnel cleared out by destroying any stray
       mushrooms within it.
    
    -  When you have completed your task, you should have something like this:
    
                                     #=MUSHROOMS

    / 8.3  Fortress /______________________________________________________________
    ----------------
    
    If you are patient, you could build a mushroom fortress around your Shooter. 
    Then all you would do is shoot Spiders for the rest of the game.  It would look
    something like this:
    
                                     #=MUSHROOMS
                                     S=SHOOTER

    | 9.  CONCLUSION |=============================================================
    +================+
    
    One of the more interesting games from my youth.  Centipede was definitely
    something that was different then all the other shooter games that were out at
    the time.  Instead of dealing with invading aliens or being in space having to
    subdue an invasion, you were presented with the problem of having to go bug
    hunting.  Not ordinary bugs mind you, but bugs that were intent on your de-
    struction.  If one didn't learn the behavior of the various enemies, you
    wouldn't make it very far in this game.  The other interesting aspect was
    getting used to the track-ball.  Most of the games used a joystick so the
    track-ball was definitely something one had to get good with.  The action was
    constantly fast paced and as you progressed through the game, things didn't get
    much better.  I enjoyed the fact that you never quite had the same game each
    time you played.  That, I figure, was what made this game a lot of fun to play.
    Unfortunately, it is very rare to find this machine anywhere.  However, through
    the miracle of emulation, a whole new generation is realizing what we "old"
    folks enjoyed those many years ago.  I hope this guide helps you in being able
    to get the most amount of gameplay for this game.  If you do have other ideas
    or thoughts, please e-mail me and share them.  Who knows, maybe I'll start a
    Q&A Chapter in this guide if enough people ask the same questions.  Anyway,
    thank you again for reading this guide.
