Ground Attack

Crash

Producer: Silversoft, 16K £5.95 This is similar to 'Penetrator' by Melbourne House, but is nowhere as good a program. It's the sister game to 'Orbiter'. Here you must attack the aliens in their underground caverns. Weapons are bombs and laser and there are fuel dumps for points. Thrust and decelerate and nine skill levels (different speeds of play) with the cursor keys and 9 and 0 for direction and fire, which is not the best arrangement. No joystick facility. There are better value games around of this type.

ARCADES BROUGHT INTO THE HOME John Gilbert reviews more complex games. Almost every major type of arcade game has been simulated on Sinclair computers. There are also new games which have an arcade format but have evolved on a microcomputer. The Spectrum is an ideal machine on which to play arcade games. The quality of them has improved substantially since the launch of the machine. Some of the first arcade games to be produced for the Spectrum were versions of Space Invaders, the game which started the arcade craze. Spectral Invaders was the first to be announced by Bug-Byte, which was already renowned for its arcade and adventure games on the ZX-81. So far it is the game which most closely resembles the original arcade version. Although it is slow it is difficult to score points, as you can fire only one laser blast at a time. Another invaders game, Space Intruders, was launched at about the same time as Spectral Invaders. The game is much faster and is recommended for those who like to keep their fingers on the fire button and amass a big score. The only criticism is that the aliens and mothercraft are very small and the mothership is blue on a black background and so is very difficult to hit. Apart from that Space Intruders from Quicksilva is good value at £5.95. Namtir Raiders, for the ZX-81, is a space invaders game with a difference from Artic Computing. The player still has to face the hordes of aliens which come down the screen but the laser base can be moved up and down as well as left and right. The player has five laser bases during the game and they can take only five hits from alien bombs. There are three levels of difficulty-easy to impossible. The game, costing £3.95, is addictive and the graphics are neither awkward in design nor jerky in movement. The game which is gaining popularity with 48K Spectrum owners is Time Gate, from Quicksilva. The authors claim that it is the ultimate in 3D arcade space action. The game is loaded in two parts, the first being a lengthy instruction manual. After the manual has finished you can load the game. The object is to destroy a race of aliens called the Squarm who are trying to colonise Earth. The enemy fighters are also seen in 3D and so are the planets on which the player can land to refuel and repair the ship. It is by far the best arcade action game so far for the Spectrum and costs only £6.95. Asteroids is also becoming popular on Sinclair machines. One of the first companies to launch a version for the ZX-81 was Quicksilva. It was a good version on such a small machine and is still proving popular. Quicksilva has also introduced a Spectrum version called Meteor Storm. It has the added attraction of speech before play. It is difficult to hear the words but we are informed by the authors that it says "Meteor Alert... Meteor Alert...". Meteor Storm is a novel version of Asteroids and costs £5.95. Sinclair Research has a good game of asteroids, called Planetoids, in its new Spectrum Software library. The asteroids are in 3D and much careful design work on both the asteroids and the player's ship seems to have gone into the game. Planetoids costs £5.95. Artic Computing seems to be the only company to have produced a version of Galaxians for the ZX-81. ZX-Galaxians looks like Space Invaders but the invaders are 'V'-shaped and are supposed to be inter-galactic birds. The birds swoop from formation and bomb the player's laser base. ZX-Galaxian is slow in action but can still be a very addictive game. It costs £4.95. Defender is still a much-sought-after game in the arcades and Artic Computing took advantage of that early by producing a version for the ZX-81. The graphics are not particularly interesting and the spaceship which the player flies across the landscape is made up of a series of blocks which look only slightly like a ship. Despite those criticisms, the original idea behind the game is still there and the Artic version can be exciting, as you see the enemy ships rushing at you from the other side of the screen. With the arrival of the Spectrum, many manufacturers found an interest in the arcade game Scramble. The best and fastest version so far is from Mikro-Gen. In the game you have to go through caves which become smaller and smaller as it progresses. The game becomes progressively more difficult and can be run in slow, normal and fast modes. It costs £3.95. Silversoft has a Scramble-type game called Ground Attack. It works on the same principles as the Mikro-Gen game but is much slower. There is a good deal of blank screen between game rounds and the average waiting time between rounds is 15 seconds. Ground Attack costs £5.95. The range of arcade-type games on Sinclair machines is always increasing. Manufacturers seem to feel safe in producing standard arcade games such as Space Invaders and Scramble. Those games, especially for the Spectrum, are becoming more imaginative and the graphics and sound more impressive. Manufacturers have to be careful about copying ideas from other games but with the imagination of some of the firms in the Sinclair market, children and many adults will be kept happy with arcade-type games on the ZX-81 and Spectrum for a long time. Space Invaders games have now been overtaken by Pacman in popularity. Bug-Byte, [redacted]. Quicksilva, [redacted]. Artic Computing, [redacted]. Sinclair Research, [redacted].

SINCLAIR BRINGS THE THRILL OF THE ARCADE INTO YOUR HOME With the Spectrum, program writers have been able to write more complex games. John Gilbert investigates this new move. Almost every major type of arcade game has been simulated on Sinclair computers. There are also new games which have an arcade format but have evolved on a microcomputer. The Spectrum is an ideal machine on which to play arcade games. The quality of them has improved substantially since the launch of the machine. Some of the first arcade games to be produced for the Spectrum were versions of Space Invaders, the game which started the arcade craze. Spectral Invaders was the first to be announced by Bug-Byte, which was already renowned for its arcade and adventure games on the ZX-81. So far it is the game which most closely resembles the original arcade version. Although it is slow it is difficult to score points, as you can fire only one laser blast at a time. By the time the laser bolt has reached the place where you wanted it to go, the target invader has moved on. That means that a great deal of anticipation and skill is required. Graphically, the Bug Byte Invaders is the best, with rows of different-colour aliens crossing the screen and large motherships moving from one side of the screen to the other at random intervals. Spectral Invaders is well-presented and costs £5.95. Another invaders game, Space Intruders, was launched at about the same time as Spectral Invaders. The game is much faster and is recommended for those who like to keep their fingers on the fire button and amass a big score. The only criticism is that the aliens and mothercraft are very small and the mothership is blue on a black background and so is very difficult to hit. Apart from that Space Intruders from Quicksilva is good value at £5.95. Namtir Raiders, for the ZX-81, is a space invaders game from Artic Computing with a difference. The player still has to face the hordes of aliens which come down the screen but the laser base can be moved up and down as well as left and right. The greater movement permitted to the player is compensated by the hail of bombs dropped by the aliens and the size and power of alien ships. There are four waves of aliens and as the game progresses the ships get bigger until the giant mothership arrives. The player has five laser bases during the game and they can take only five hits from alien bombs. There are three levels of difficulty - easy to impossible. The game, costing £3.95, is addictive and the graphics are neither awkward in design nor jerky in movement. The game which is gaining popularity with 48K Spectrum owners is Time Gate, from Quicksilva. The authors claim that it is the ultimate in 3D arcade space action. The game is loaded in two parts, the first being a lengthy instruction manual. After the manual has finished you can load the game. The object is to destroy a race of aliens called the Squarm who are trying to colonise Earth. To do that the player must fight the enemy in space and go through time by locating a series of Time Gates to find the Squarm's base. The pleasant thing about the game is its graphics. The player is at the controls of a space fighter and look out into a 3D representation of space. The enemy fighters are also seen in 3D and so are the planets on which the player can land to refuel and repair the ship. It is by far the best arcade action game so far for the Spectrum and costs only £6.95. Asteroids is also becoming popular on Sinclair machines. One of the first companies to launch a version for the ZX-81 was Quicksilva. It was a good version on such a small machine and is still proving popular.

Despite those criticisms, the original idea behind the game is still there and the Artic version can be exciting, as you see the enemy ships rushing at you from the other side of the screen. Now that the Spectrum has arrived, many manufacturers have found an interest in the arcade game Scramble. The best and fastest version so far is from Mikro-Gen. In the game you have to go through caves which become smaller and smaller as it progresses. There are four sectors to the game, including Missiles, UFOs and Meteors. The player has to destroy the missiles which are fired from the ground at the players' ship, destroy UFOs with a laser blaster, and dodge the meteors. The game becomes progressively more difficult and can be run in slow, normal and fast modes. It costs £3.95. Silversoft has a Scramble-type game called Ground Attack. It works on the same principles as the Mikro-Gen game but is much slower. There is a good deal of blank screen between game rounds and the average waiting time between rounds is 15 seconds. Ground Attack costs £5.95. The range of arcade-type games on Sinclair machines is always increasing.

Space Invaders games have now been overtaken by Pacman in popularity. A number of them have been produced for the ZX-81 and several companies are producing them for the Spectrum. It looks as if Pacman may provide the next boom in Sinclair software - but that is another story. Bug-Byte, [redacted]. Quicksilva, [redacted]. Artic Computing, [redacted].

SPECTRUM SOFTWARE Simon Beesley brave attacks by trolls, bombardment by meteoroids, alien invasions and even English literature to bring you up to date with Spectrum software. The quality of Spectrum software has improved since our last survey but originality remains in short supply. Most of the programs looked at are games programs and the bulk of these are modelled on the arcade classics, Space Invaders, Pac-Man, Defender and Asteroids. Perhaps this is because the games-buying public is only interested in games that fall into a recognisable category. Some of the programs are written entirely in Basic. This need not count against them unless the program displays moving graphics. The Spectrum's keyboard is not very suitable for fast-moving games although Quicksilva and Softek offer a joystick option on some games. Sinclair has released a large range of programs written for them by ICL and Psion. By and large the ICL programs compare badly with those from Psion and have a rather amateurish look to them. Each of the tapes in the ICL games series, Games 1 to 4, contains four short Basic programs with titles such as Galactic Invasion, Skittles and Train Race. These are the sort of programs a reader might like to key in from a listing in a magazine. They are fairly simple and afford a limited entertainment for a short period. In view of their variety each package represents reasonable value although they are perhaps more suitable for young people. ICL has also produced five titles in a Fun to Learn series covering Music, History, English Literature, Geography and Inventions. They present a variety of quizzes on their respective subjects. Players can compete against each other in a race in which correct answers send them further along the track. It is difficult to know who these programs are aimed at. One soon runs through the stock of questions and the same names appear in different types of question. Some of the information presented is too obscure or eccentric to make the programs suitable for schools. In the English Literature quiz, for example, Ian Fleming rubs shoulders with Shakespeare and little-known seventeenth century playwrights. Psion's collection of programs is far more satisfactory. Hungry Horace is loosely related to Pac-Man but has a number of original features. Horace has to eat the flowers in a park while avoiding the park guards. Sinclair gives a fair description of Horace as a subtle and amusing cartoon-style game. Psion's 48K chess program was written in conjunction with Microgen. It plays a remarkably strong game even at the lower levels. As an averagely competent player I found it quite hard to beat at level two, although its play seemed to come adrift under pressure. The program's response time is quick and the pieces are quite easily distinguished. Space Raiders and Planetoids are Psion's versions of the arcade games Invaders and Asteroids. Anyone who still has an appetite for these games will find the Psion products more than adequate. With Vu-Calc, Psion has scaled down a Visi Calc-type program to the dimensions of the home micro. These programs, which are commonly used on business micros, are usually described as providing a financial spreadsheet. They enable the user to lay out financial data in rows and columns and enter formulae to run calculations on parts or all of the table. Vu-Calc supplies a range of commands for entering data, text or formulae and performing calculations. Basic programs which have been compiled by Softek's compiler, Super C, run - typically - 10 times faster. The compiler sits at the top of memory above RAMtop and is unaffected by a New command. It leaves room for a Basic program of up to 8K and a further 10K for data. The present version cannot cope with decimals, arrays or string variables. These limitations need not be too constricting. Strings, at least, can be stored in the data areas as ASCII codes and accessed through Peeks. At £14.95 this is good value; particularly since it enables people to write commercially respectable programs without having to master machine code. However Softek insists that anyone planning to sell programs created with the compiler should negotiate for the rights. Softek claims that trace elements have been included to detect code written with Super C. The arcade game Asteroids crops up on almost every micro. Softek's version Meteoroids is one of the fastest for the Spectrum with good colour and sound. Softime supplies the Spectrum with a digital clock and alarm at the top of the screen which remains there while other programs are loaded and running. The last program in Softek's list is Zolan Adventure, a standard text adventure game which has the merit of fitting into 16K. Quicksilva gave Time Gate considerable advance publicity claiming it would make as great an impact on the computer games' world as had Atari's Star Raiders. As it turns out the game closely resembles Star Raiders. Given that the Atari is a rather more sophisticated computer it is not surprising that the Spectrum version of the game does not match the original. Time Gate presents a view from the cockpit of a spaceship. An instrument panel below contains a long-range scanner and a variety of other indicators giving information on the ship's position and damage incurred. Your mission is to clear 18 galactic sectors of enemy craft. The business of locating and firing on enemy ships is not as interesting as attending to all the other procedures. The controls are not as responsive as on the Atari. Nonetheless this is an elaborate game with excellent graphics - certainly one of the best so far for the Spectrum. In an impressive piece of synthesised speech Quicksilva's chess program announces itself at the beginning with 'this is the Chess Player'. Rather startlingly the packaging relates how the Chess Player, an Evil Being, has called for a challenger from Earth. The planet's survival hangs on your game - and you thought you were just going to have a quiet game of chess. In the event the program plays quite a strong game with the option of six levels of play. The board is clearly displayed and the pieces are well designed. Psion's chess program, however, is probably the better player. Meteor Storm, another version of Asteroids, also announces itself but rather indistinctly. There is not much to choose between this and Planetoids or Meteoroids. The major problem for software companies writing an Asteroids-type game must be in finding an alternative title. Spectres from Bug-Bvte gives a novel twist to the Pac-Man concept. Eddie the electrician has to rewire a haunted house. Instead of eating or picking up objects in his path he lays down light bulbs. Reaching one of the four power generators enables him to illuminate the house and drive off ghosts. The game has a highly individual flavour. The characters which glide around at a fairly leisurely pace, are engagingly different from the standard Pac-Man figures. This is one of the more original games yet to appear for the Spectrum. Gulpman from Campbell Systems is also based on Pac-Man but refreshingly breaks away from the standard format. It offers a choice of 15 different mazes and allows the speed of play to be set. At the highest levels your little man dashes around the maze at quite a pace. By contrast Jega's Specman, written in Basic, is dismally slow. Sometimes the ghosts seem to be stricken with paralysis and unwilling to take up the chase. Escape from New Generation Software is a variation on the maze theme which involves escaping from dinosaurs. The dinosaurs - brontosauri, pterodactyls and such like - pursue the player's character with considerable animation through the maze which is shown in bird's-eye view. Silversoft's games Orbiter and Ground Attack are probably the best Spectrum versions of the arcade games Defender and Scramble. Ground Attack requires the player to fly a plane through a series of caverns and avoid or destroy missile attacks from the ground. Scramble from Work Force is similar but marginally slower. Likewise Avenger - Abacus' version of Defender - is competent but not quite as accomplished as Silversoft's. MYSTERY MEETING A gold sundial worth £6,000 is the prize for the first person to solve all the clues in the adventure game Pimania. As in Kit Williams' book Masquerade, deciphering all the clues will lead the winner to a meeting at a specific time and place with representatives from the authors of the game, Automata Ltd. The other side of the program tape contains a disco single. Automata say that the clues are scattered in the music, the program and the graphics. Although we did not proceed very far with the quest the music and opening graphics seemed to bear out Automata's claim that the world of the Pi Man is totally bizarre. Melbourne House has based The Hobbit, on the novel by Tolkien. It helps to have read the book in finding your way about. The Hobbit is claimed to be an advance on other adventure games because it introduces other characters from the book who react to the player in the role of Bilbo with an independent life of their own. It also allows you - in a limited fashion to enter sentences rather than single words as commands. In practice these extra features do not amount to much and give the program greater scope for the sort of inconsistencies adventure programs are prone to. Thorin, for example, repeatedly enters the scene and tells you to hurry up. This is irritating because you were unaware that he had left and he seems to be totally devoid of constructive ideas. It is not a good idea, however, to kill him off since he sometimes proves too strong for your attack. Furthermore the manual suggests that you should stay on good terms with the other members of your party if you are to succeed in your quest. Many of the locations in the adventure are illustrated by some excellent graphics. We only managed to complete 7.5 percent of the game during which the text was accompanied by six different pictures. The graphics coupled with a more varied plot than usual make The Hobbit superior to any other adventure games available for the Spectrum. Both the assemblers tested, from ACS and PI software, require Z-80 mnemonics to be entered in Rem statements and both allow addresses to be replaced by labels. The ACS assembler, Ultraviolet, costs twice as much at £7.50 but offers several extra features. It allows multiple statement lines and provides five pseudo-instructions such as DEFS, which inserts a string of ASCII characters at the current assembly position. ACS also supplies a disassembler, infrared. Like the assembler this has two different versions for 16K or 48K machines. The program is easy to use and docs all you might expect from it.
