Well it's far into the future and the Americans and Russians are still going at it hammer and sickle. Now the Soviets have developed a new MIG Starfighter, a highly dangerous and sophisticated weapon currently being constructed in a secret factory deep within the Siberian wastes. For extra security the plane has been split into different modules and scattered throughout different workshops. With the MIG spread over such a large security complex it's going to take a real American super hero to infiltrate the factory and steal the parts of the plane. Or someone really stupid.
The security system within the factory is mainly based around a colour coded card/lock system. At any one time a data card and a lock card can be carried. Holding a lock key that matches the colour of a door grants you access to the region behind it. In the higher security sections an appropriately coloured data card is also needed to open coloured doors.
Cyborg guards patrol areas of the factory complex, blindly following their pre-ordained paths. Contact with a guard causes one of the four micro batteries running your protective suit to lose a third of its power and you return to the start of the current screen. If all four batteries are out of action, the environment stabilisers in your suit pack up and you expire.
The factory itself is made from a series of rooms each with a number of gantries and walkways making up the scenery. There aren't any ladders connecting the thoroughfares but one way transporter beams serve a similar purpose. These appear in the form of arrows in the platform floors. Whichever way the arrow points is the way you're transported if you stand over it and press the activate button. The transportation is immediate but it's worth waiting before transporting for any cyborgs that may be trotting over the landing pad to get out of the way.
Stealthy super secret agent that you are, your actions include walking left and right along gangways and activating objects you don't have a gun, so cunning rather than violence is called for.
Most factory chambers contain a couple of main doors that connect with other parts of the complex. Travel through one of these portals and another chamber flicks into view. The all important sections of the MIG fighter are shown as flashing squares. Guide your guy over one of these and a small detail of the overall MIG SF is added to a growing picture in the status area at the top of the screen.
Different pieces of lock and data card are also imbedded in the floors. Standing over one of these floor plates and pressing the activate button causes an exact electronic image to be copied into your data or lock store, wiping out the current image stored there. Sadly, you can't just wander about the factory opening all the doors and then running off to collect all the parts of the Starfighter since the doors reset and relock themselves when a room is re-entered.
Some circuitous routing is involved in completing the task, and you often have to retrace your steps in a chamber once a door has been opened, so that you can re-copy an appropriate lock or data pattern into your status area before proceeding.
