1. Introduction
Earth invasion is a fun to play space combat game. In this game, you
are a fighter pilot for the Yanchooz. They are an evil race led by the
terrifying Emperor Xyfud Plasfoc and they try to conquer every form of life
in the universe.
The Yanchooz did succesfully conquer many races but they have problems
with the humans. Your main goal is to destroy all terran resistance from
the planet Xanculkor to the Earth. This way, the Yanchooz race will be
able to launch a massive attack against the human HQ. If you succeed,
you will make the Yanchooz the most powerfull race of the universe.
But there is one major problem. You will have to do the job in solo.
In fact, before this mission, you had nothing but poor results as a
fighter pilot. To tell you the truth, you have been selected to do this
mission because the Yanchooz Imperial comission wants you dead. They send
you on this mission so you can do as much damage as possible to the
humans before they kill you. The only thing that can save your life now
is the total success of your mission.

3. Starting the game.
To start the game, type EARTHINV <ENTER> at the DOS prompt.
If you are a registered user, you will have to answer a question to
prove your registration. The answer will be found in the The Pilot
Master Ship Book. Non registered user will not have to answer this
question but will have a limited version. If you do not want sound
effects, you can add the /s option after the program name.
4. The menu.
The menu let you pick one of the five option available. These options
are:
4.1 Start your mission : This option lets you begin your mission.
4.2 Restore game : Use this option to restore a previously saved
game. If there are no game saved, this option
is the same as starting the mission.
4.3 View High Scores : You can view the top five Yanchooz pilot.
4.4 Ship option : Let you switch the sound on and off and the
control mode (joystick or keyboard).
4.5 Quit the game : Let you quit the game and return to dos.
5. The game.
5.1 Playing the game
To start the mission, choose the option "Start your mission" from the
menu. You will then receive your pre-mission briefing and leave the planet.
To achieve your main goal, you must pass throught 10 missions. Each one
of them provide you with five fighter-fighter fight and one fighter-capital
ship fight. Unregistered user will only be allowed to do the first five
mission and, therefore, will be unable to achieve the final goal.
For each of the ten mission, you will recieve an onboard communication
that tell you exactly what to do.
Once in a fight, you can use the controler to move your ship up and
down while using the firebutton to fire at enemy ship. Keep a look
at your shield level. Every time you get a shot from the enemy, your
shield level is going down. if it gets below 0, you are dead. Your
ship is equipped with 30 HIJKE* to shield converters which
can help regenerate your shield when it is too low. Every time you catch
a HIJKE capsule, one of your converter is used to regenerate your shield.
* HIJKE is a form of energy used by the Yanchooz for many purposes. Some
HIJKE float into space and look like yellow capsule with blue sparks.
5.2 THE SHIP'S BOARD
At the left most part of the board, you can see your shield level. You
will have to look there very often.
At the right most part of the board, you can see the comunication
and status computer board.
At the center top, you see your position indicator. This instrument
show you how far you are from your goal.
In the lower part of the board, on the right, you can see your score,
and, on the left,the amount of HIJKE to shield converters left.
5.3 THE CONTROLLER
5.3.1 Joystick
Push the stick up to make your ship go up and pull it down to
make your ship go down. Press any firebuttons to shoot at enemy.
5.3.2 Keyboard
Press the SHIFT key to make your ship go up and the CTRL key
to make your ship go down. Press the ALT key to fire at enemy.
With any of the controller, you can use the F7 key to save your game
(registered user only) and the F3 key to toggle sound on and off. The
save game option always save at the status of your ship when the last
mission started. For example, suppose you save your game at mission 7 when
you passed throught 3 fights. When you will restore it, you will have to
start mission 7 at the begining.
*Using the joystick is not recommended if you have a slow computer. To
maintain a maximum compatibility with all system, I used the slow
BIOS interrupt instead of direct port access.
6. TROUBLESHOOTING.
1. You are not able to enter the game.
Three possibility can bring that problem:
-Some files are missing.
-The file REGQUIZ.REG contains information that MUST NEVER BE
MODIFIED. If the program detect any modification in this file,
it will abort the game.
-Your system is not a 80286 or better.
*NOTE: If these files have been modified, you are asked not to
upload the program on any BBS. You should try to get
a clean copy of the program before doing so. If you can't
find one you can order the game from the adress below. It
will cost 10$. You will receive the code sheet and the
secret pasword. Specify you want a copy of the program.
2. You cannot restore a saved game.
- Perhaps the saved file have been erased or modified.
- Only registered user can use this option.
3. The game is too slow.
-Try playing with the keyboard instead of the joystick.
7. REGISTERING EARTH INVASION.
It is my hope that Earth Invasion will be a great source of enjoyement
to all. It has been released as shareware to reach the most people. I
believe that shareware is a good way to entertain people for a lesser
price. This program is complete. However, you will have to register to
get to some parts of the program.
If you enjoy Earth Invasion and wish to register, send a check payable
to Eric Boutin to the following adress:
Eric Boutin
472 Des Pins
Amos, Quebec
Canada, J9T 1A3
NOTE: Please notify what CB software product your are registering.
If you register 10$ or more, you will receive the secret password and
code sheet both required to remove shareware notice and have access to
the entire game.
