Game
Info
Overview
- Asteroide is a copy of
Atari's Asteroids. The italian company Maxenti built this cab and used
parts (PCBs and Control Panel) of the clone manufacturer SIDAM who
developed an own Clone of Asteroids (own PCB's and own cab) named Asterock. The color scheme on
the Control
Panel is the same as the original Asteroids, but has a different
control panel layout and -graphics. The bezel around the monitor is
black and the sideart is completely
different. Maxenti used a vector monitor from Hantarex (Italy).
Description
- Same gameplay as Asteroids from Atari. You find your spaceship
suddenly to appear in the middle of an
asteroid
field. To get relief for yourself from the dangerous situation you need
to
blast away the slow-moving asteroids that drift randomly through space
and are blocking the way to further levels. When hit, the large
asteroids will break in
two smaller pieces that need to be shot at again making two more
fragments
that need a last shot to be dust eventually and dissappear. You control
your ship by rotating it left or right and you can
accelerate with the "Thrust" button. Take care, you are in space, so
no braking via air friction. To stop your ship from travelling
endlessly int the sam direction you need to turn
180° and press the "Thrust" button again until you stop. From time
to time saucers
will appear and shoot around, randomly in the beginning, but then more
and
more precisely into the player's spaceship direction. The smaller kind
of saucer
is deadly with the 3rd or 4th shot if the player doesn't react. As a
last resort you have the ability to use the "Hyperspace" button to
suddenly dissappear from your current place in space and reappear at
another random location on the screen. However you don't know
where you will reenter the universe, it may happen just right into an
asteroid! Once all asteroids have been shot away the next level starts
with more
asteroids and saucers appearing earlier and more often.
