Welcome Shocktrooper Squad Commander. Our intelligence sources have intercepted a coded message that says Aliens are planning to conquer earth.
Your mission is to infiltrate the alien base and destroy it. You must also escape with the parts for their new TRG-5 Space Saucer and return them to our Scientists for analysis. Four highly trained Shocktroopers will be placed under your command for this mission, each Shocktrooper is supplied with the latest in attack equipment.
Lasers — The Alien Base has two types of Laser the first emits powerful Energy Bolts that can kill, destroy them with your Electro Gun; the second type is a Rotating Laser which can be stunned but not destroyed, shooting one of these will stun all of them off the screen. Laser Mirrors reflect Enemy Bolts.
Zaproids — Robots that enter through openings in the ceiling and move downward — don't go near them as they can electrocute you.
Force Fields — Certain passages are blocked by wave like force fields to eliminate a force field, you must destroy the power generator with your Electro Gun.
Filter Grids —Some tunnel sections have filter grids attached to the floor and ceiling, your Electro Gun will not operate in these tunnel sections.
Terminators — Walking Robots that beam onto the screen and attack with a high powered Laser — defend yourself with your Electro Gun.
Particle Emitters — The most important areas of the base are protected by rows of ceiling mounted emitters which drop radio active particles, being hit by a particle raises your radiation level drastically.
Your radiation exposure is shown by a bar meter at the top left corner of the screen the level increases whenever enemy lasers fire, each time you fire the Electro Gun or use the Inviso Device, or if you are hit by a radiation particle. Your Shocktrooper will die if the radiation level reaches the area at the top of the meter. There are three decontamination chambers where your Shocktrooper's radiation level may be reduced to zero, if the door does not open as you approach, you must have failed to set a Bomb on one of the previous screens, enter the chamber to be decontaminated, receive your bonus and one of the specially miniaturised Space Saucer parts. Press the Joystick button when all action stops to continue your mission.
The Aliens have captured many brave Troopers and doomed them to special brain-draining chambers throughout the Base. Each chamber must be disabled to prevent the Aliens from obtaining vital secrets — moving past a chamber causes a brain-drain system to stop functioning.
Score and High Score are displayed at the top of the screen the number of Shocktroopers remaining is shown at the top right.
