IntroductionOVERVIEWIf you've ever thought ab m}out the tiny particles of the subatomic world, you must have wondered about those protons and photons, so small that no one h n}as ever seen them. Here's a game that takes you to that subatomic world -- in search of the elusive Weakons. Your objective o} is to capture as many Weakons as you can and deliver them to the generator at the center of the screen.But watch out! You p}r craft shrinks to subatomic size, so you have to use your joystick to dodge the particles zooming from right to left acoss t q}he screen. You crash if a meson or gamma photon or ionizing radiation cloud hits you. If you don't blast the mesons away, th r}ey come back to get you. You seek out the Weakons that appear every 20 seconds, and guide them carefully to the generator. s}When you dock in the center barrel, the energy dial registers your total.Capturing several Weakons causes the particle acce t}lerator at the bottom of the screen to speed up, making your task even more hazardous. But your score mounts and eventually u}you're awarded more lives for your skill. There are ten difficulty levels that you can choose as you grow more expert at the v} game. Challenge a friend to try the two-player version, too.REQUIRED ACCESSORIES One ATARI Joystick per player w}16K RAM ATARI 810 or 1050 Disk DriveCONTACTING THE AUTHORUsers wishing to contact the author may write to him at x}: P.O. Box 10005 Balmoral Auckland New Zealand Getting StartedLOADING WEAKON INTO COMPUTER ME y}MORY1. Remove any program cartridge from the cartridge slot of your computer.2. Plug your joystick controllers into the z} first controller jack of your computer console. (To play the two-player version, plug two joysticks into the first two cont {}roller jacks.)3. a. Have your computer turned off. b. Turn on your TV set. c. When the busy light goes out, open t |}he disk drive door and insert the WEAKON diskette with the label in the lower right hand corner nearest to you. Close the do }}or. (Use disk drive one if you have more than one drive.) d. Turn on your computer and your TV set. The program will lo ~}ad into computer memory and start automatically.THE FIRST DISPLAY SCREENWhen the program has loaded into computer memory, } the following screen displays: WEAKON 1983 (C) ERIC FREEMANSECOND DISPLAY SCREENThe following soon } appears to replace the first display screen: 1 PLAYER GAME PRESS SELECT FOR 2 PLAYERS PRESS }OPTION TO CHANGE LEVEL 01 PRESS START TO BEGIN GAMESELECTING GAME OPTIONSDifficultyThe title scre }en shows difficulty level one. Press the OPTION key to raise the level as far as 10. You may hold the OPTION key down conti }nuously to change levels.During game play press the OPTION key to return to the first screen. Then press the OPTION key ag }ain to advance levels.Number of PlayersYou may play WEAKON with one or two players. The game is set at first for a one p }layer game, but you can switch it back and forth by pressing the SELECT key. Playing WEAKONAfter you've made y }our choices, press the START key to begin the game. The shrinkage process begins as your craft appears in the middle of the }screen. The accelerator is at the bottom and the proton/antiproton target is on the right. Almost immediately particles she }d off the target and streak from right to left toward you. Destroy them by pressing the joystick button when they're in line } with the center of your craft.The gamma photons are shaped like horizontal bars with jagged edges. They're attracted to t }he electromagnetic field around you. They're hard to hit, and they destroy you if they hit you first. If you dodge them suc }cessfully, they just disappear off the left side of the screen.The ionizing radiation isn't as difficult to destroy. It's }a larger target with an indistinct shape. But it usually has some angular deviation, so you should maneuver quickly in front } before you fire.Less frequently a large meson darts about the screen. It's a large figure with some particles surrounding } it. Destroy the mesons! They're attracted to your craft, but unlike the photons, they don't disappear off the left side of } your screen. They might come back after you just when you think you're safe.The Weakon appears about every 20 seconds. I }f you can catch it with the "cup" at the top of your craft, the pulse generator appears in the middle of the screen. Maneuve }r towards the left side of the generator and place the Weakon in the center barrel. When you've docked accurately, the energ }y dial appears and you're disconnected from the Weakon. Each unit of energy is worth 10 points.After a short delay the shr }inkage begins again, and you're back in the energy vortex.LEVEL ADVANCINGCatching two Weakons increases the accelerator e }nergy. This means your playing level goes up and things happen faster. There are ten levels in all but if you survive the t }enth (it's highly unlikely!) the speed of play remains at that level.SCORE PANELIn the one-player game the score panel at } the top of the screen appears as follows: YOUR SCORE 000000In the two-player game the score panel looks like this: } PLAYER ONE 000000 PLAYER TWO 000000SCORINGYou score points for destroying advancing particles and catching Weakons, a }s follows: POINTS TABLE GAMMA PHOTON ... 20 POINTS IONIZING RADIATION ... 40 }POINTS MESONS ... 60 POINTS WEAKONS FROM 650 TO 1280 POINTSMISSILE FIRINGYou can fire the weapons on } your craft continuously by holding down the joystick button. But the key to winning the game is dodging projectiles fired o }ut of the target proton/antiproton.LIVES REMAININGThe number of lives remaining is displayed by the figures at the bottom } center of the play field. This tally doesn't include the craft you're using. For example, at the beginning of play when yo }u have four craft, you see three figures on the display, besides your present player.EXTRA MANAn extra craft is allotted }when you gain 10000 points. This bonus is displayed in the "lives remaining" position.HIGH SCORE DISPLAYThe computer kee }ps the highest score earned since you loaded the program. This is displayed when all players have lost all their craft in an }y particular game. You may move either joystick in any direction to restart the game when the high score is displayed.LEVE }L DISPLAYThe current skill level is displayed in the bottom right corner of the playing screen. There are ten levels incre }asing in difficulty from 1 to 10. Interrupting the GamePAUSINGPress the space bar on your keyboard to freeze th }e display and stop play temporarily. Press the space bar again to resume play.RESTARTING A GAMEPress the START key at an }y time to restart your current game. HintsUse continual vertical motion to avoid the photons, which aim d }irectly for you if you stay still.The photons are difficult to hit, but tapping the joystick often works better for lining }them up than more aggressive movement.Get as many points as you can in the lower screens before catching any WEAKONS. } You must aim at the center of the ionizing radiation and the mesons to destroy them.Stay towards the left side of }the screen if possible. This allows more reaction time. Author's FootnoteThis game was inspired by the search }for the elusive Weakons, massive elementary particles thought to be the carriers of the weak nuclear force. The group of thr }ee particles more properly known as intermediate vector bosons are currently being sought in the products of high energy part }icle collisions, most notably in the end result of colliding a proton beam with a counter rotating antiproton beam. The thre }e varieties proposed by the vague electroweak theory are the charge W+ and W- and the neutral Zo. The former two may have be }en observed recently at the European Organization for Nuclear Research (CERN) facilities in Geneva. After observing a billio }n high energy events, two separate groups working with different detection apparatus decided five candidates' collisions show }ed unambiguous evidence for the existence of the W particle.The Z particle, thought to be ten times as rare as the W bosons }, won't be seriously looked for until the 2000 billion electron volt particle accelerator at Fermilab is completed in 1985. }The current energies achieved at CERN approach 540 billion electron volts (540 GeV).By comparison the mass of the W Weakon }has been tentatively determined as 79.5 GeV with the Zo weighing in at 90 GeV. The particle's large mass is a consequence of } the manner in which the weak nuclear force acts over very small distances. The massless photon, carrier of the electromagne }tic force, is thought to have an infinite range so conversely it was proposed in 1935 by Japanese physicist Hideki Yukawa tha }t the carriers of the weak and strong nuclear forces must have mass. Th moderatley heavy pi meson was found to be the carrie }r of the strong force in 1947. This indicated that the shorter acting weak force must use a heavier carrier, but no machine }existed at the time with sufficient energy to search for it.In the late 1960s and 70s a theory unifying the electromagnetic } and weak nuclear forces was developed independently by a number of physicists and the search for Weakons was on in earnest a }gain. By finding this particle the electroweak theory will be one more link in the chain towards the grand unification of al }l nature's forces.REFERENCE AND INSPIRATION:David B.
