Banks of aliens dropping from the sky, defending laser
scurrying from right to left on ground. That's right, just when
we thought we'd defeated them long ago (and gone on to better
things), invaders are back!
Graphics are not bad although the bombs are pencil-thin and the
magenta colouring difficult to see against black. Explosions are
unspectacular, landing aliens only affect you if you're stupid
enough to be immediately underneath and the laser reminds me
of an egg cup with cosy. No loading or insert instructions but
left, right and fire, keyboard or joystick, are explained on
screen.
I liked playing this version, which may not be the recommendation
it seems. That I could manage to survive clearing several screens
with a respectable score, probably means it's far too slow for the
expert zapper. And sometimes, all that was needed was to stand still
and press fire. But as an ego booster for those dextrous among us
or beginners, this is cheap and cheerful.
