INTERDICTOR PILOT - THE ULTIMATE SPACE GAME the background idea of Interdictor Pilot is not novel. The player is flying a space fighter called Interdictor Mark II. After taking off from home starbase he has to traverse space at light speed until such time as he meets an opponent. When this occurs he is automatically taken out of light speed, does battle and, if successful, re-enters light speed until the next encounter. After a certain distance through space - depending upon his rank at the time - he will arrive at the first starbase, dock and report in, saving a record of his achievements, or otherwise, to disk or tape. If all goes well and he is sufficiently skilled he will progress through the ranks of Sub-Lieutenant, Lieutenant, Lieutenant-Commander, Commander, Captain and finally, Commodore. So far as is known, no-one has achieved the latter rank, including the author. The higher the rank, the greater the length of time during transits between starbases and the more frequent the contacts with the enemy. The above is a not uncommon, even perhaps rather mundane, description of a space flying/fighting game. What makes Interdictor Pilot the fantastically interesting and fascinating pastime that it is, is the way in which the author has built on the basic theme. For instance, for a TRS-80, we think that the graphics are a little short of miraculous. Actually this is probably not too surprising because Interdictor Pilot is written in machine code and occupies the full 16K. As an example of the graphics, the illustration shows the screen through which the pilot plays the game. To describe this in detail is beyond the scope of this sales literature, but briefly, the large section in the middle entitled 'Vision Screen' is the pilot's view into space. When leaving or arriving at a starbase a three dimensional tunnel appears, through which the pilot must navigate. When leaving he is, of course, taking off from zero velocity, and is therefore nicely aligned, hence a few touches of the controls here and there will keep him on the straight and level out of the tunnel. When arriving at a starbase, however, the position is rather drastically changed. The opening of the tunnel is displayed and it is for him to manoeuvre himself so that he not only flies into it, but also along it. In view of the fact that the aircraft is proceeding at a very fast speed, this small part of the game is no light achievement on its own. Normally, however, as we have said, the vision out through the screen is of space and this is really most amazingly realistic. The heavens seem to proceed across the screen almost exactly as one would imagine in real life. For instance, if, since last either leaving a starbase or coming out of light speed, you have manoeuvred the aircraft and then seek to re-enter light speed after an encounter, however much you have manoeuvred, a scanning device in the fighter will automatically re-align you with the next starbase. The effect is, you just sit there and watch the heavens pass by. Another amazing graphic realisation is that of an approaching enemy. Up in the left hand corner of the illustration you will see an area entitled 'Ranging'. This is split up into eight compartments. When you first come out of light speed the graphic area next to the figure 8 will be illuminated. As you get closer to the enemy, the succeeding areas will light up. This ranging instrument therefore, on its own, tells you how far away the enemy is, but the visual effect of him approaching you is quite astounding. He starts off as what appears to be a stationary star. As you increase speed to approach him and, as the ranging indicators decrease from 8 to 1, so he gets larger until eventually you can make out the details of the craft and recognise it. If you are approaching him and do not collide with him, then he or you will swerve to one side and the effect as he passes over, under or to the side of you is extremely impressive. You almost want to duck. One of the many alternatives open to you when you play the game is what is called the Simulation mode. This is strictly a practice mode. You have to take off from a starbase in the normal way, but once in light speed you can choose the type of aircraft to fight, or indeed you can also choose to practise docking with a starbase. Again, this simulation mode is not too astounding a feature in a game such as this, many of them have them, but what is amazing is that the author has included a command whereby the enemy may be 'paralysed'. In this mode he is not allowed to move or fight. You can literally fly up to him, circle round, see him from any angle and then fly away again. We find this to be quite uncanny in its realism. Probably the illustration does not give a fair representation of the screen and instrument panel. The various areas marked are illuminated when in use. For instance, on the right hand side of the illustration, you will see a section entitled 'Transponder'. If this is switched off, then that area next to the word 'Off' will be lit. If it is on Standby, then that section will be lit and so on. This is a particularly fast way of assimilating information. The scenario for Interdictor Pilot is as follows: It is now 5 years since 11 battlestations of the Jahdra-Gallan Alliance first appeared in Federation airspace, thus violating the terms and conditions of the Limhof Concord. Early diplomatic efforts on the part of the Federation to avoid open confrontation were frustrated when the 9 members of our Representatives Commission failed to return from their fifth negotiations visit to the Alliance mothership, Kontarkohsz'. Fifty Interdictor Mark I craft were despatched from the nearest Federation starbase on a punitive mission against 'Kontarkohsz' - none returned. Communications received from the last few surviving Interdictors, as they tried to make good their escape, indicated that the defences of the formidable Jahdra-Gallan battlestations were impenetrable to our craft. They remain so to this day. The Federation has, therefore, adopted a policy of attacking their patrol ships and drones in outer space - a task to which the Interdictor Mark I was admirably suited. However, our losses in the early stages of the conflict remained high, in part because the excellent enemy fast patrol craft, the Jahdran Aggressor, was a more sophisticated copy of our own Interdictor Mark I, and also because our own craft would often stray accidentally into battlestation airspace. Such unfortunates were destroyed without exception. Our performance in the conflict was dramatically improved with the introduction last year of the new Interdictor Mark II craft - our fleet is now made up entirely of these craft. As well as being faster and more powerful, it has many new systems, including automatic avoidance of battlestation airspace while at light speed cruise. As a newly commissioned Interdictor Pilot, you will therefore never experience Battlestation airspace. Consider yourself very fortunate! You will, however, encounter the Jahdran Aggressor, Gallanic Cruiser and Meson Torpedo drone of the Jahdra-Gallan Alliance, as well as fellow Interdictor Mark II craft and Federation Meson Torpedo drones. It is hoped that if we can sufficiently deplete their vast fleet of craft, their battlestations will be forced to concede an untenable position and withdraw. Interdictor Pilot comes with what are effectively two separate manuals. The first is a short page or so prepared by Molimex on how the program is loaded and the idiosyncrasies of it when used on Tandy Model I and III machines. This section is completed with instructions for a very quick demonstration flight. The main part of the manual is a fully illustrated document written in 'real time'. It assumes that you are a novice pilot that has just been given your first Interdictor Mark II and it takes you through the craft description of both the Interdictor Mark I and the newer Mark II, plus the theory and practice of the deflectors, propulsion, stabilisers, Saturn array, Lewis array, weapon systems, cockpit display and light speed drive. The next section of the manual goes through, in great detail, the cockpit display and this is followed by descriptions of the controls and their operation. Craft types and Sortie format are described, followed by a section of combat advice, a description of the starbases and finally the use of the simulator. A Sortie, incidentally, is made up of the launch, the transit, which includes the light speed jumps and encounters with the enemy, and finally the recovery at starbase. The Sortie format mentioned above describes these sectors in full. What more can you say? Interdictor Pilot is written by a serving RAF navigator and in our estimation sets new standards for micro-computer game software.
