After selecting the playing mode, pressing the
START/PAUSE key will first play the prelude
music before the game starts.
·
In mode 1 there is only one enemy figure. The
player can use the left, right, up and down
keys to move the figure to the best position
then use the PUNCH or KICK key to attack
the enemy.
·
If the playing figure is attacked by the enemy
figure it will immediately fall down. When
this happens the player must press the up key
to recover or be subjected to continuous at
tacks.
·
When the enemy¢s score reaches zero the
game objective has been reached and the
overall score will be increased by one. Every
playing mode has a maximum score of 99.
When this has been reached it will remain at
this value and not increase any more.
·
If the player¢s score reaches zero, the game
will end and the overall score will be recorded.
The flashing game over message will be dis
played.
·
In mode 2, there are two enemies that have to
be attacked and destroyed to win the game.
·
In mode 3, aside from the two main enemy figures there is an additional enemy figure holding a weapon who can attack the player. The
player cannot attack this enemy, and can only
dodge out of his way.
·
In mode 3 this third enemy figure with the
weapon can appear at any time on the top left
or right side of the screen. This enemy figure
is able to work out the best place to attack the
player who must be careful to dodge out of the
way.
·
Mode 4 combines all the three modes.
Starting from mode 1, after the game has
been won or the barrier reached, the game
will then move to mode 2, then to mode 3.
·
The higher the overall score the faster the en
-
emy figure¢s actions will be.
·
In modes 2 and 3, the second enemy figure
will attack from behind, so the player must be
careful to dodge out of the way.
·

The START/PAUSE key will put the game
into a temporary wait state. The conditions of
the game prior to pressing this key will be re
tained even if the game has been switched off
manually or automatically. When the game is
again started, the player can resume from
where it stops when the START/PAUSE key
was initially pressed. If the machine is
switched off outside of this temporary wait
state then the conditions of the present game
will not be stored and the game has to start
from the beginning.
·
When the game is over the message ²GAME
OVER² will flash on the screen and the game
will enter a wait state. Pressing the
START/PAUSE key will allow a new game to
start or pressing the PUNCH/MODE key will
allow a new mode of playing to be chosen. Or
press ON/OFF to switch off. If within 30 sec
onds no key has been pressed the system will
begin to free run in the demonstration mode.
·
The ON/OFF switch controls the power supply.
Calculating the score
·
When the game begins both the player and
enemy¢s score is 9.
·
Every punch, kick or weapon hit (mode 3) will
initially mean a reduction of the opponent¢s
score by one. But the actual score deducted is
dependent upon the opponents score. If the
opponents score is 9 then 0.9 will be deducted,
if the opponents score is 8 then 0.8 will be deducted and so on in the same way. However
due to the limitations of the LCD pattern the
decimal number will not be shown.
·

·
Sound effects
·
-
If within 7 seconds no attack is made then the
score will be increased by one but only up to a
maximum of 9. This applies to both player
and opponent.
When the opponent¢s score has been reduced
to 0, the objective of the present game has
been reached. When the player¢s score
reaches zero, the game is over.
