Abadox - The Deadly Inner War

Instruction Manual



In the year 5012, a strange cytoplasmic creature is sighted in your galaxy.
It's Parasitis! A deadly, formless mass which feeds on all life forms and
assumes the shape of its swallowed prey! Parasitis rapidly advances upon your
home planet, Abadox, and engulfs it!

From nearby space stations, the World Alive Force launches a full-scale attack.
But the massive Parasitis crushes the entire squadron! An orbiting hospital
ship is even swallowed whole - with the beautiful Princess Maria on board!

You are Second Lieutenant Nazal, the lone survivor of the Force. Sidelined 
from the action by your ship's faulty energy drive, you witness the attack! 
But it's not too late to join the battle!

Now your weapons are ready and your ship has been repaired! Jettison from your
spacecraft, ignite your power pack and zoom into Parasitis' grisly surface.
Your Mission: To blast your way inside Parasitis' nightmarish body and battle
your way to its Core - to destroy it!

Fight your way inside its deadly mouth! Travel down its throat, through its
nerve center - battling hordes of enemy antibodies and bacteria! Use lasers,
guided missiles, and special orbiting shields to destroy them! Beware the
Guardians that ward off all intruders - bombard them with fierce fire power!
You must succeed to save the Universe and rescue Princess Maria!

Prepare to blast off! Your Mission begins!

How to Play

Your Challenge: The Stages of Combat

Including Parasitis' surface, there are Six Stages that you must complete. 
Your Object: To battle your way into Parasitis' massive body, reach its Core
and destroy it!

Each stage will lead you further into the unknown inner world of Parasitis'
body. You'll travel through its cavernous mouth with its treacherous fangs and
tongue, down its dangerous throat and into the risky area of the esophagus!
Then, suddenly, you'll enter a fluid connector channel which takes you straight
into the stomach and intestinal region! The final stages lead you through
Parasitis' energy nerve center to its heavily protected inner Core.

For more details about each Stage, see pages 10-12 [below -tsr]. Note: Only a
few of the amazing graphic images seen during these Stages are shown in this

The Enemies Within

As you fight your way to the Core, you'll encounter the strange creatures that
live inside Parasitis. Hideous eyeballs, twisted worms and mutant skeleton 
fish are just a few that will swarm in for attack as you progress! But not all
appear in each stage and some hold hidden surprises. For each one you destroy,
you'll rack up points for your score. To check your score, view the continuous
scoring update in the upper left corner of your screen.

To advance within a Stage or move from one Stage to the next, you must destroy
Parasitis' Guarding monsters. (For example, see Deathface and the Cilia mon-
ster shown on the package!) As each one is destroyed, you'll gain entrance to
a new part of Parasitis and add to your score! Beware! Your journey becomes
more treacherous with every Stage you complete!


Your Lives

At the start of the game, you'll receive 3 lives. Once you've used them up,
the game is over! However, you may then select Continue and re-start the game
in that particular Stage you just ended. You will automatically receive 3 new
lives, but you'll lose all weaponry except for your basic fire power! You can
select Continue as many times as you wish.

Your Weaponry

Throughout the game, you'll encounter deadly blue scorpions. They appear both
horizontally and vertically as shown at right. Destroy them and collect their
special Blue Power Capsules. Gather as many capsules as you can - they'll give
you advanced weaponry such as the Tresbeam, the Paradora Gun and guided miss-
iles! Some capsules will allow you to maneuver more easily; others will contain
special defensive shields and armor.

Note: Not all weaponry is available in each Stage. For example, the Laser Gun
is only available during the vertical Stages. See the Weapons Chart on pages
8 and 9 [below -tsr] for more details.

damage! Acquire up to 3 glowing eyes of armor!


The Six Stages of Internal Combat

Stage 1
Fly over the twisted, gnarled surface of Parasitis! Fight snapping jaws and
cunning skulls - a sampling of Parasitis' mutant armies. Beware the hideous
dog-like monster, Bau, who guards the entrance to Parasitis' mouth! Destroy
him and you're inside! Blast past the treacherous fangs and tongue! Then ven-
ture boldly through the bone-crunchers! If you thought Bau was a fearsome foe,
the Guardian Deathface will be a real treat to defeat!

Stage 2
Now you're in the throat! Weave your way carefully down this muscular canal.
Battle single-cell organisms and pods of poisonous spores. Watch out for the
Hands of Death! An unwary visitor is most welcome here! Soon, a circling
Guardian will try to entrap you. Destroy it and then blast into the risky
channel of the esophagus! This narrow part of Parasitis' digestive tract is 
the realm of the Lizards of Doom. Surprise! The final Guardian will greet you
with a fanfare of deadly stars!

Stage 3
Suddenly, you're in the Deadly Forest of Blue Nerves. Dancing flowers wave
about as they scan for intruders to kill! Pass quickly through a twisted 
channel of frozen nerves and meet the great Shark Guardian head-on! Defeat him
and enter another fluid channel.

This inner sanctum is inhabited by floating larvae and vicious hydrozoa - 
among others. Grab those weapons! You'll need them when you meet the final 
all-seeing Guardian!

Stage 4
Now plunge downward into Parasitis' stomach. Beware the cellular organisms 
that detach from the walls! They'll demolish and food (such as you!) so the
stomach crabs can crunch away!

Battle the King Crab as it guards the final digestive chamber! Here, the 
dreaded Cilia monster pummels anything that passes by! Avoid its pulsating
horns if you can!

Stage 5
Be careful as you maneuver through this intestinal channel! Armed insectoids
will mobilize to attack you - along with many mechanical devices. Look out for
enemies above and below!

Destroy the 3 powerful Guardians so you can blast into the next chamber - the
energy nerve center! Electrical charges and more await you! Destroy the
Guardian Commander quickly or you'll never survive!

Stage 6
Zoom down the Tube of Death, avoiding heat-seeking fireballs and other macabre
organisms. Watch out for the hazardous energy bars with their electrical

Five Guardians protect the door to the Core. Destroy them to reach the last
corridor! Every weapon counts here as you battle the final armies of Parasitis!

Winning the Game: Enter the black inner chamber and destroy the Core! Find
Princess Maria and rescue her!
