3.) About Striker.

Striker is a grapichs oriented game for the IBM personal
computer series. In STRIKER the player is placed in control
of a helicopter whose mission is to navigate various tunnels
in order to complete five seperate missions of skill. The
game includes four sepearate skill levels which allows for a
wide range of end user playing skill.Many other conveniences
are included in STRIKER. The user can center the screen and
select color pallette. The user can also redefine the entire
set of controlling keys to his preference. High Scores, for
the four different skill levels, may be displayed and
cleared. The game includes keys to pause, toggle sound on
and off, and abort the game at any time. The program also
allows a wide variety of joysticks to be attached. By using
the Adjust Joystick option in the other options menu the
game can handle joysticks of widely varying resistance and
a varying number of buttons. STRIKER is designed to be easy
to use. The program on boot-up automatically determines the
computer, PC,XT or Jr, that it is on and the number, if any,
of joysticks attached to the computer. This makes setting up
the software an option and not a requirement.

--------------------------------------------------------------------------------
4.) How to play STRIKER.

The mission in STRIKER is to navigate the helicopter through
various tunnels and successfully complete the five separate
missions. Various obstacles, including 5 different kinds of
aliens, gun turrets and missles, try to keep the player from
completeing his mission. The player is given two means of
defense: bombs and bulletts. By using the bombs and bullets
the player may shoot down the various aliens and obstacles
for points. There are various fuel canisters located along
ground. These canisters give no point values but the do
resupply the helicopter with fuel. The player must resupply
his fuel in the later levels or he will run out of fuel
due to the manuevering required in the later levels. Once
the player has completed the tunnel he then must complete
one of five missions. These missions are described in detail
in the section entitled "Mission Information". After the
game is completed the computer checks to see if the score
achieved is good enough to be saved to a high score table
and if so the user is asked to input his name and the score
is saved to one of the four separate score boards. One board
is maintained for each skill level.

--------------------------------------------------------------------------------
5.) Controlling Striker.


This section tells how to control the helicopter through
the joystick and keyboard.

Predefined Function Keys.
-------------------------

IBM PC and IBM PC XT and COMPATIBLES.

CTRL-P - Pause game.
CTRL-S - Toggle sound on and off.
CTRL-NUM LOCK - Pause game. (NOT ON PCjr.)
CTRL-SCROLL LOCK - Abort Game. (NOT ON PCjr.)
CTRL-B - Abort Game.

IBM PCjr.

CTRL-P - Pause game.
CTRL-S - Toggle sound on and off.
CTRL-B - Abort Game.

Movement Contorl Keys.
----------------------

There are four primary keys for movement. They are initally
defined as the cursor control keys on the cursor pad.

^
|
| UP ARROW IS USED TO MOVE HELICOPTER UP
|
LEFT KEY MOVES <---- ----> RIGHT KEY MOVES HELICOPTER RIGHT.
LEFT |
|
|
V DOWN KEY MOVES HELICOPTER DOWN.


These keys may be pressed and released at any time. The
helicopter will continue to move in the direction of the
pressed key until that key is released. More than one key
can be held down to produce diagonal movement. If two
opposing keys are held down moition on that axis is
cancelled out.For example is the up and down keys are both
held at the same time the helicopter will level out and
will move neither up or down. The ability to hold and
release keys makes STRIKER easy to control from the
keyboard.

The SPACE BAR fires bullets from the helicopter.

The "X" key drops bombs from the helicopter.

The ESC key is defined as an alternative pause key.

All of the above key definitions can be changed. See the
section entitled "Other Options Menu".

JOYSTICK CONTROL
----------------

A joystick may be used to control the helicopter. The
joystick may have up to two buttons. If the joystick has
only one button that button will fire bullets. If the
joystick has 2 buttons the first button will fire bulletts
and the second button will drop bombs. When joysticks are
activated the bomb and fire keys and well as the function
keys are still active on the keyboard. This allows users
with one button to drop bombs from the keyboard.

--------------------------------------------------------------------------------
6.) Aliens and Point Values.

There are five types of aliens. Of these five types four
can be destroyed and give point values between 20 and 80
points. The fifth alien is a Space Mine. The Space Mine is
impervious to attack and cannot be destroyed. However the
Space Mine is incapable of firing shots. The player must
avoid the Mine beacause any contact with the mine will
destroy the helicopter. The Gun Turret on the ground scores
120 points. The Missiles score 80 points and the FUEL
canisters score a fuel bonus but no point value.

--------------------------------------------------------------------------------
7.) Mission Information.

There are five Missions.
They are:

1.) PICK UP YOUR SPIES

In this mission you must pick up your spies. A small
bunker will move onto the screen with a landing pad. The
player must land on the pad and wait for the spies to run
out to the helicopter. If the player takes off again and
runs into a spy, the spy is killed. If all three spies
are destoryed the player has failed his mission and
receives no bonus for the mission. The player may pick up
only a few of the spies but this will lower the bonus
points for the mission.

2.) DROP OFF YOUR SPIES

In this mission you must drop off the spies picked up in
mission one. If all three spies were destroyed in the
first mission no building will scroll onto the screen and
a message will be displayed informing the user that there
is no mission to be completed beacause the spies were all
killed. Otherwise a building with 2 helipads will scroll
onto the screen. The helipad on the left is for 2 men and
the helipad on the right is for the last spy. Once the
spies are dropped off the mission is complete and a bonus
will be awarded.

3.) PICK UP CARGO

In this mission you must pick up three containers of
cargo. In order to pick up a container you must land on
it with the helicopter level. The landing runner must
also be perfectly level with respect to the box. Once you
land on the box it will be loaded into the helicopter. If
you land improperly on a box the helicopter will explode.

4.) RESCUE STRANDED PEOPLE

In this mission you must rescue people from a burning
building before the fire reaches the top of the building.
If you run into a person on top of the building that
person is destroyed. If a person is on top of the
the building when the fire reaches the top that person is
destroyed. There are three people to rescue altogether.
If the helicopter runs into the building or is on the
building when the fire reaches the top it is destroyed.

5.) DESTROY MISSILE FACTORY

In this mission you must destroy the missile factory
before three missiles are loaded onto the truck. You can
bomb the missile factory to destroy it. There are three
sections to the missile factory and all three must be
bombed in order to destory the factory. However, the flow
of missiles can be stopped by bombing either the truck or
the converyor belt.

Scoring.

The first time a mission is played it is worth a possible
bonus of 1000 points. Each mission after that is worth
1000 points more. However, on missions 1-4 points are
awarded on how successfully the mission was completed. In
other words if the player resuces only 1 spy in mission 1
he receives 25% of the possible bonus or 250 points. If
he rescues 2 he recieves 50% (or 500 points) and if he
rescues all 3 he receives 100% (or 1000 points). This is
the same for the other three missions and is tied to the
number of people, or in the case of mission the number of
boxes, rescued or retreived.

--------------------------------------------------------------------------------
8.) Other Options Menu.

These menus allow you to configure STRIKER for your
praticular machine. The menus are as follows:


Game Demonstration.

This is a prepetual running demonstration of STRIKER.

Display High Scores.

This menu displayes the high score table for the current
skill level.

Joystick Adjustment.

This menu allows you to calibrate STRIKER to your own
set of joysticks. The computer will determine whether
you have one or two joysticks and if you have only one
the computer will automatically select that joystick. If
you have two joysticks the computer will ask you which
one to use. The computer will then ask how many buttons
are on the joystick. After this slowly rotate the
joystick around its outer edge. This will allow the
computer to determine the resistance of your joysticks.
After this press return and the game will be set up to
use your joysticks.

Adjust Keyboard

This option allows you to choose the keys you will use
to play STRIKER. The computer will ask for 6 different
keys: UP, DOWN, LEFT, RIGHT, BOMB, FIRE BULLET, and
PAUSE. The pause key you define is in addition to the
CTRL-P key which is automatically defined. The default
key assignments are:

UP : Up key on cursor key pad.

LEFT : Left key on cursor key pad.
RIGHT : Right key on cursor key pad.
BOMB : "X" key.
FIRE BULLET : SPACE bar.
PAUSE : ESC key.

Adjust Display.

This option allows you to center the screen and choose
from the two avaliable color pallettes. Center the
screen by using the cursor key pad arrow keys and
change the pallette by using the "P" key. Press ENTER
when done to save the values to disk.

Reset High Score List.

This option clears the high score table for the current
