Directions
To
help you in your task, your ship has been equipped
with an array of weapons and
counter-measures (described below).
Increase the effectiveness of your ship's
weapons, and your ammunition supplies by
collecting the powerups which appear after
each destroyed alien attack wave.
Weapons
| Weapon |
Key |
Description |
| Blaster |
<space> |
This
is your ship's main weapon, and is
the only weapon for which you have
infinite ammunition. This weapon
be upgraded to fire more shots at
once. |
| Missile |
w |
This
weapon launches a missile which
will attempt to home in on the
nearest alien. Can be upgraded to
improve the missile's homing
ability. Ammunition for this
weapon must be collected. |
| Laser |
a |
This
weapon fires a singe laser beam,
which will cut through anything it
comes into contact with. If well
aimed, this weapon can destroy
several aliens with a singe shot.
It can be upgraded to increase the
size of the beam (potentially
increasing the number of kills
with each shot). Ammunition must
be collected for this weapon. |
| Cluster
Bomb |
d |
The
most powerful weapon available to
you, this weapon is designed to
destroy several aliens with a
single deployment. Press the 'd'
key once to launch the weapon, and
while the bomb is in flight, press
the 'd' key once again to detonate
it. Once detonated, the bomb will
create an expanding shockwave that
will destroy all aliens it
engulfs. This weapon can be
upgraded to increase the size of
the detonation shockwave (making
it easier to destroy more aliens
with each detonation). Ammunition
must be collected for this weapon. |
Defensive
Measures
| Measure |
Key |
Description |
| Shields |
<up> |
Your
shields will remain activated as
long as you hold down the 'up'
(arrow) key. While the shields
are active, you will not be
harmed by alien weapons.
However, you will not be able to
fire your own weapons while your
shields are activated.
Additionally, you have a limited
amount of shield energy (as
indicated by a bar at the bottom
of the screen), and once your
shield energy is used up, you
will not be able to activate
your shields until you collect
more shield energy power-ups.
|
| Teleport |
<down> |
By
pressing the 'down' (arrow) key,
you can teleport your ship
instantly to the other side of the
screen. Use this feature to
quickly escape bombardments by
alien weaponry, or to collect
power-ups on the other side of the
screen. The teleportation device
also has the beneficial side
effect of confusing alien missiles
which are already in flight,
making them unable to home in on
you. |
Power
Ups
After
you destroy each wave of aliens, a
power-up will become available. They will
appear at the location of the last
destroyed alien, and fall down for you to
collect. By collecting these power-ups,
you can upgrade your weapons (making them
more powerful as described above), or
increase your ammunition supplies. Try not
to miss them!

of unknown size and origin, and it's your job to
save us all. Shoot the different aliens as they

attack back. Remember, our fate lies in your
hands; do us proud! |
