Orbiter

Crash

Producer: Silversoft, 16K £5.95 This is a much better game than Silversoft's 'Ground Attack' and is a good version of the classic 'Defender' of arcade fame. The animated graphics are neat and the sound amusing. Control keys are much better placed than in GA as well. Climb, dive, thrust, reverse, hyperspace, smart bombs and laser all help you protect the humanoids from the marauding alien craft. Features an excellent long range scan. No joystick facility. M/C.

ORBITER Silversoft Lawrence Tout I have been receiving ZX Computing for about a year now but am amazed to have never seen Silversoft's Orbiter reviewed. So, now I have chance to tell the readers what a fantastic program it is! It's nearly exactly like the arcade game 'Defender', You have to travel in your ship across the hilly landscape blasting any green aliens you come across. The aim of the game is to retain 10 blue objects which lie along the bottom of the screen amongst the landscape. You are given these at the start of each game and the green aliens try to attach themselves to these and move towards the top of the screen. The aim is to first blast the alien and then catch the falling blue object before it hits the ground and is destroyed. Points are given for catching and returning it to the ground safely. However, if you don't stop the alien and it reaches the top of the screen, it changes into a purple coloured alien. Its movement is much more erratic and they move faster making them difficult to hit. The layout of the keys is cleverly done and they include up, down, thrust, fire, change direction, hyperspace and smart bombs. If used, the smart bombs destroy everything on the screen with an impressive flash. Besides the resident aliens there are also, blue and purple squares which move diagonally across the screen laying mines, as well as innocuous looking yellow saucers which never move except when they are hit, when a hoard of smaller red saucers are unleashed. The entire activities of all the aliens are shown on a long-range scanner at the top of the screen. As you progress through one attack-wave after another, you are awarded extra ships and smart bombs. I've found that after 200,000 points the computer becomes very generous with these. One drawback with Orbiter is that you are only shown a maximum of three ships and three smart bombs on the screen, so if you have more than three it is impossible to tell how many more. One time, out of curiosity, I let my ships be destroyed and found that I had 18 ships apart from those three shown (this was at about 350,000 points). The danger in this addictive game is that if the green aliens swipe all your blue objects there is a flash, the landscape disappears and from then on all the aliens are automatically changed into mean purple ones. The secret to survival is not to, at any cost, let this happen, because if it does you're in trouble. So when down to the last blue object, instead of setting it down on the ground after taking it from the alien, hold onto it - for long as you do, no aliens can pick it up. Then you try to reach attack-wave 10, where you are given five free blue objects after every attack-wave. At £5.95 I think Orbiter is well worth the money.

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.
