Electric Pencil Company's version of Asteroids for the ZX81 is the best I have played. It has superb instructions, it is fast, has great graphics and good game options. The spaceship was cleverly represented by either an 'A', 'V', 'D' or '0'. Block symbols from keys Q, W, E and R were used for 45 degree angles. There are four sizes of Asteroids and these were just about right. Their speed varied during the game - getting progressively faster. The game has five speed levels. Level 3 should satisfy all but those of you who score a billion points for 20p. There is an option for doubles or singles and the five top scores and names can be displayed. A great game for one or more players, this version of Asteroids is manufactured by the Electric Pencil Company at £3.95.

FIRING TO ESCAPE Who can resist blowing up asteroids? To have them careering about in the privacy at your own home is sheer ecstacy! But what flavour do you prefer? This game has been multiplying at an alarming rate and with so many about how do you choose? The first consideration must surely be how fast, there is little point getting either a game that is so slow that it bores you to death or so last you find it unplayable. Next consider the controls you are offered, rotate lett, rotate right and fire are universal but what of hyperspace and thrust? Is the thrust of the move stop variety or a true inertial thrust (turn round and thrust to stop yourself moving). Then you may consider features: How many sizes at rock do you get? Two, three or more? How many saucers do you get, do they fire at you? Have you a wrap around screen? What does the game look like? Does it have hi-res graphics, colour? Does it have different attack waves (more rocks each wave)? Does the game have an attract mode, full scoring, high score, bonus ship? Finally, does the game have any special features such as particularly outstanding graphics, sound or speech? A game that has most of the above features is likely to be fairly close to the arcade original and give you hours of entertainment. MARK EYLES

GAMES GLOSSARY If you can tell a Pacman from a Defender and a Galaxian from a Space Invader you probably know your way around computer games. But if some of the game terms we have used in this supplement, or in the issue itself, are new to you, then this page should supply the answers. In it we take some of the best known types of computer game and describe how they are played and what features these games normally incorporate. So, if we claim that Penetrator is a "Scramble-type game" and that leaves you just as much in the dark about what to expect, then below there is a full description of Scramble to put you in the picture. ASTEROIDS The Asteroids came into the arcades courtesy of Atari. It features a small dart-shaped craft controlled by the player which can rotate left or right and thrust or fire in the direction it is facing. There is one further control, the panic button (hyperspace) which lets you travel to another part of the screen chosen by the computer. The enemy is mainly made up of large asteroids which sweep across the screen in large deadly groups of rock. When blown up these break into smaller fragments worth extra points. There is extra danger supplied by two UFOs. The first larger creature you'll meet fairly early on. It tends to spray shots in all directions and often crashes into an asteroid. The smaller variety is far more deadly in its own shooting and also more difficult to hit. Each cleared screen means you start again with extra asteroids. DEFENDER You can't expect to keep a finger on every control button in Defender or you'd end up in knots. The action, which takes place above an alien landscape, involves some seven control buttons and takes patience to gain proper mastery of your lone craft. That patience can be rewarded though, as Defender is challenging from the word "Go". The Defender craft can go: up, down, thrust forward, reverse direction, fire, smart bomb and hyperspace. Ten humanoids wander on the landscape and these may fall prey to raiding alien creatures known as Landers. Landers pick up the humanoids and take them to the top of the screen. If they succeed in getting there the Landers turn into fearsome mutants hellbent on your destruction. In all there are six alien opponents. On top of Landers and Mutants, these are: Pods are quite harmless but contain the small and persistent Swarmers; Bombers seed space with white bombs and Baiters only appear if you take too long clearing a screen of the rest of the aliens. If all 10 humanoids are captured, the planet explodes and all remaining alien life attacks your craft at once. Defender games usually feature a small radar screen which shows what is going on at all parts of the planet surface. FROGGER Frogger has spawned a whole host of computer games with a similar theme. This game features a frog hero who must jump across a road and make his way across a river torrent to five frog-holes in the bank. The busy road usually features live streams of traffic travelling in both directions at varying speeds, between which the player must hop his frog without wrapping it around any fenders. Once across the road, the river can be crossed by leaping onto floating logs and onto the back of swimming turtles, until our frog can enter a vacant spot in the far bank. Turtles have a habit of diving though so don't let a frog dally too long on one. Being carried off the edge of the screen (by log or turtle) also results in a note in the funeral column of Amphibians' Weekly. When all five frog-holes have been filled, the game becomes more difficult with extra traffic being added to the road, snakes traversing the bank between road and river and alligators appearing instead of logs in the river. A timer running down on each frog also adds to the difficulties. The arcade original also featured a small lady frog who could be "picked up" on the logs and offered a lift home for a bonus. Other bonuses can be scored by entering a frog-hole in which a tasty fly meal has come to rest. DONKEY KONG Donkey Kong is the strange name for a climbing and jumping game which features a starlet-grabbing monster gorilla. Often referred to as Crazy Kong or Crazy Climber in the computer circles, it has only just found its way onto the home screen. The game features a gorilla holding a girl captive at the top of the screen and an intrepid hero (Mario the carpenter), who starts at the bottom of the screen. Between the two is a connecting network of platforms and ladders up which Mario must run to achieve his rescue. Kong hurls barrels down the screen and Mario makes use of his "jump" button to leap over them. He can also grab a hammer and smash the barrels as they approach him. Once at the top of the screen a new complex is built with Mario, again starting from the bottom with a view to rescue. This time the screen features a series of conveyor belts and deadly fires which travel around on the ladders and belts. GALAXIANS The Galaxians were the sons of Space Invaders. Instead of proceeding down the screen at a leisurely pace, they wavered at the top of the screen before swooping down in batches of two or three (or more often on a solo mission) firing bombs. The player has the usual left, right and fire controls on his laser base and must take care not to get trapped in a corner. He scores double points for a galaxian hit in mid-swoop and there are bonus points for taking out the red fleet commanders, who usually descend flanked by their generals, dispersing bombs at such a rate that the first instinct is to flee for cover. That is the essence of Galaxians but with each destroyed platoon, new waves appear at screen top and their attacks become more frequent, more accurate and, all too often, more deadly! PACMAN The ghostly world of Pacman is made up of a dot-filled maze, a hungry dot-eater and four pursuing spectres. Pacman variations can be found under a whole range of titles from Vic-men to Gobbleman, Snapper to Super Glooper and many others. Most dot-eating games are related to it. The main character is the dot-eater, which travels around the maze, eating every dot he touches. His objective is to clear the screen of dots. He is hampered in this by the four chasing ghosts whose touch is lethal. The Pacman's main defence against the ghosts, who usually number four, are energiser dots. These pulse in the four corners of the maze and, upon being eaten, reverse the roles for a short while. This means that Pacman can turn the tables on the ghosts and eat them for bonus points. He is allowed only a few seconds of dominance before the usual hunter and hunted rules come back into operation. It is also usual for fruits to appear on the screen occasionally and these too can be consumed by Pacman for bonus points. When Pacman has cleared the screen, it refills with dots and the game restarts except that this time the ghosts are a little livelier and a new fruit, worth extra points, appears at this level. SCRAMBLE Scramble should have a big one-way sign on its cabinet. The screen rolls from right to left, taking the player's craft along it into ever-increasing danger. Scramble variations often contain the word "Mission" or "Attack" but there are some weird and wonderful titles about. The player controls a craft heading right across the screen over hilly terrain His craft can never turn around and opt out of its mission but he does have some control over his destiny. His controls are up and down, fast and slow and he can both bomb and fire at his enemies. The Scrambler is not usually equipped with enough fuel to complete his task, but it is normal to obtain more fuel by bombing fuel tanks on the ground and so (mysteriously) replenish his own stocks. The enemies come in all shapes and sizes. Most common are missiles which fire up from the ground as your craft passes overhead and alien invader creatures which frequently inhabit caves and fly at the player's craft. The original Scramble game sent the player through a series of different terrains with new challenges in each section. And most computer Scrambles attempt to duplicate this with a number of different stages. Scramble requires a cool head which can find the right control in a crisis, but it makes an ideal computer game as success naturally leads to new and more difficult stages. INVADERS Space Invaders started the whole computer game craze back in 1977 and most gamers know the format backwards. Still, just a brief resume... The invaders come in waves above the ground and move in rows across the screen one step at a time, firing missiles earthwards. When one row of the aliens reach an edge of the screen, the whole platoon jump down a line and return back the way they came. When they achieve their slow progression to the bottom of the screen, the game ends. The player controls a laser base which moves left to right and fires directly up from its position. His aim is to blow up the entire fleet before it reaches the bottom of the screen. Flying saucers move across the top of the screen in both directions and can be hit for a mystery bonus score. In the arcade original, top saucer scores of 300 were achieved by firing 22 shots before shooting at the first saucer, then firing 14 shots in between each subsequent saucer. Some computer versions have copied this technique.
