General Description

The HT1132A is a single chip Space War LCD
Game designed by HOLTEK. This LCD Game
has two modes (mode 1 and mode 2) of playing.
In mode 1, enemy's space shuttle appears with
two types of musical accompaniment at differ-
ent stages and shoots

laser beams at

the player's space shuttle. The player's space
shuttle then immediately shifts right or left to
avoid the attack and fires back with his own

laser beams. In mode 2, enemy's space shuttle
can quickly shift from up to down or from left to
right, but it can not fire laser beams. The
player's space shuttle can move right or left to
the best position for firing laser beams. If it hits
the target, a 50 bonus point is awarded and a
HAPPY melody is played. If no target is hit,
then no score is added and a sad melody is
played.

The player's space shuttles consist of three
types. In accordance with the different
weapon equipments, there are three kinds
of laser beams (

, , ).

he energy propor-

tion is 1:2:4. Enemy's space shuttles are also
equipped with

, ,

laser beams. Their

energy proportion is 1:2:4. For example, de-
stroying the enemy's space shuttle " "
needs to fire either

once or

twice, while

could penetrate it. Energy contrast table is
shown as follows:

At the major stage, if the space shuttle is hit
three times, then the game is over. In such
circumstances, if the START/ON or OFF
key is not pressed within 4 seconds, the
game goes into free-run mode. The free-run
mode's auto power-off timer can be set by
adjusting the PPO switch of port P to 1 for a
4-minute time-out or to 0 for a 2-minute
time-out.

During the game, the enemy's spacecraft,
the player's laser fire, and destructive
sounds are all accompanied by their corre-
sponding sound effects. A melody is played
to celebrate the rise to a new level when the
the last level has been successfully com-
pleted. When the game is finally over, there
is finale.

The highest score can always be saved un-
less the power is turned off. Pressing the
RESET key can clear the highest score.)

MODE2

To enter mode 2 press the RIGHT key and
hold it down, and then press the START/ON
key.

Once in MODE 2, the highest score is shown
and a START melody is played. At this mo-
ment, the Enemy's space shuttle will
quickly shift from left to right, up to down.
The player can shift the space shuttle and
fire laser beams. When the target is hit, 50
bonus points are awarded and a jubilant
music is played. When the target has been
missed, regret music is on.

There are sixteen opportunities to shoot.
Each shot is worth 50 points, hence the
maximum score is 800. The highest score
can be saved. After the 16th shot, the game
ends and goes into free run mode. At this
time, power is automatically switched off
after 16 DEMO MODE.
